We often work on building applications where a single application might scale to multiple instances with couple of changes. A good example for this case will be, when you are building an application for multiple countries. Different countries might have different requirements i.e different sections or different form fields, but the base application i.e common part should remain same. TLDR; This becomes even challenging when the application is already build and in later stages of application lifecycle, it needs to scale to multiple countries. What are the approaches people follow in the market ? - Fork & maintain multiple repositories (Hard to believe, but happens) - Multiple replica copies country-wise in same repo (Doesn’t make sense) - IF-ELSE-IF-ELSE-IF ladder, hell! (Sprint ending this week, let’s wind it up) - A/B testing Segmentation (We’re Frontend Developers not Devops) - and on… The solution should prevent us from maintaining multiple repositories, prevent DRY (Don’t Repeat Yourself), encourage separation of concerns, doesn’t ship not required code, ease development & deployments which should be done from Frontend. Mixins & Dynamic Imports to the rescue !! (Presenting this concept in Vue Conference, Bangalore, India) Let's continue: Quick Refresher- Mixins (Vue): It is a flexible way to distribute reusable functionalities for Vue components, you can even define lifecycle hooks in it - It can be imported in multiple components - Mixins can be in your country specific component code Overridden - Only override the function which need changes over the function imported from Mixin, Vue will manage the merge of both Dynamic imports (Webpack): This allows you to split your code into various bundles which can be country specific javascript chunks, loaded on demand or in parallel How to implement this ? We will have one parent AppBody in each country folder, it will contain multiple reusable child components like <user-profile-form> required. < > template < > div < > user-profile-form </ > user-profile-form < > user-password-reset </ > user-password-reset </ > div </ > template The child component will import and override the base mixin app/ feature code. Let below be code of one of the child component of AppBody.vue parent file. userInfoMixin Utils ; { : [userInfoMixin], methods: { 
      setTheme(data){
        Utils.setTheme( );
      }
    },
    mounted() { .countryCode = ; .setTheme();
    }
  }; import from "../../mixins/UserInfoMixin.js" import from '../../common/Utils' export default mixins //Base code 'pt-br' this "+55" this Now our Directory Structure: Above we have country specific folders to maintain separation of concerns, respective country developer can’t mess with any other country code. We have to keep above discussed child component in the respective country folder, the base code will go in the common folder. How to switch countries ? userInfoMixin Utils ; { : [userInfoMixin], methods: { 
      setTheme(data){
        Utils.setTheme( );
      }
    },
    mounted() { .countryCode = ; .setTheme();
    }
  }; import from "../../mixins/UserInfoMixin.js" import from '../../common/Utils' export default mixins //Base code 'pt-br' this "+55" this The AppBody is the parent component, different for different countries holding the child components which are inheriting from JS & SCSS Mixins Apart from invoking using query params, you can use webpack variables which will help you in build & deployment process using: REGION=INDIA npm run build Running the above command will give us region/country chunks (0,1.. below) which are loaded dynamically (only specific country chunk)after the base app code, which is just app.js 53.3 kb. So in the end, only your country code is loaded. apart from base app.js. Extending CSS Using Mixins of SCSS: Now adding SCSS code to our AppBody.vue file. @ ; { { : ; : ; : solid ; : ; : ; : ;
 	} {
 		appearance: none; : transparent;
 		-webkit-appearance: none;
 		&: : -webkit-inner-spin-button, &: : -webkit-calendar-picker-indicator, &: : -webkit-clear-button {
 			display: none;
 			-webkit-appearance: none;
 		}
 	} import "../../assets/scss/component-styles/userBasicInfo.scss" //base code .basic-info /*overriding with country specific requirement */ input width 100% padding 10px 0 border-bottom 1px #e6e6e6 font-size 16px color #000000 border-radius 0 input [type='date'] background Now, above methodology ensures the parent code which is same, is not re-written and only the different requirement needs to be written by overriding the parent function in the inheriting JS Function/CSS Class. The separate country code chunk will be loaded dynamically during rendering after the base app code, Also the build process can be made country wise by passing webpack variables during the deployment, which means one country release will be independent of others. The above method is one of the possible solutions. If you came across the same requirement, I would love to hear the solution from you.

Scaling Vue App for Multiple Instances

We’re fresh on the heels of the Google and Reddit version of “Let’s Make a Deal.” To the tune of $60 million per year, tech behemoth Google has been granted real-time access to its catalog of user-generated content for the purpose of training Google’s . AI models As Reddit moves toward going public, the $60 million presents itself as a viable new revenue stream, perhaps setting a precedent for other tech companies to follow in their footsteps by turning user data into a new revenue stream in a legal manner. Hey, if Reddit can do it, you can do it too! Let’s first take a gander at how Reddit and Google are pulling this off, then explore an option that can make a business cash while also fostering loyalty from their users: As it pertains to Reddit users, the legality comes from the Reddit Terms of Service agreement. When creating or submitting content to Reddit, users agree to grant Reddit a “worldwide, royalty-free, perpetual, irrevocable, non-exclusive, transferable, and sublicensable license to use, copy, modify, adapt, prepare derivative works of, distribute, store, perform, and display [the user’s] Content and any name, username, voice or likeness provided in connection with [the user’s] content in all media formats and channels now known or later developed anywhere in the world…and you irrevocably waive any claims and assertions of moral rights or attribution with respect to [the user’s] content.” This is, of course, legalese for “We, Reddit, can pretty much do whatever we want with your data.” So, this is a legal monetization of data via licensing, however is it an ethical means of monetization? That’s for you to decide. Reddit is a big enough website with few viable competitors that it can, for the most part, monetize user data without any form of compensation given to users and not have to worry about losing a meaningful chunk of its user base. One Reddit user, u/Morrissey_99, asked in the r/technology thread on the deal, “[So] do I get a part of that $60M Reddit? It’s my data you were using, after all”. The answer, of course, is no Morrissey_99 you will not. You agreed to royalty-free, perpetual, etc., etc., licensing of your data prior to using the Reddit product. \User data is a hot commodity. Whether it’s AI training, quantitative trading, marketing measurement, or improving internal products and systems, it’s clear that data has tremendous value. Reddit’s data is worth $60 million annually to Google. That’s a lot. If you’re reading this, you’re probably not Reddit- or Google-sized, but you probably are sitting on a lot of data that can be productized and, in turn, monetized. But how do you do that in a way that works for everyone? How do you do it in a way that is ?  It’s pretty basic: be transparent and give users something they actually want in return. very cool 😎 Welcome to the revolutionary world of generally-speaking-do-things-in-the-opposite-way-of-Reddit-and-Google method monetization, where legalese takes a long walk off a short pier,  the Morrissey_99s of the world get compensated for their clearly valuable asset, and businesses open up a brand recurring new revenue stream from an asset they already have or can acquire with (relative) ease. I realize monetizing data is technically not doing the opposite of Reddit, but it is perfectly alright to borrow goals (turn data into revenue) from Reddit, but probably not advisable to borrow their systems (make it so users can’t use your product without forking over their data). Anyway… Explicit Consent is Key, Rewards Entice Whether it is the content generated on a website, app usage details, transaction history, or demographic information, the impetus is on the user to decide how that data can be used. Data privacy regulations like GDPR and CCPA make it abundantly clear users need to know what the heck is going on with their data and give them the options to decide whether the data can be used at all. The Reddit solution, essentially creating a gigantic blanket statement that allows them to do essentially whatever they want with the data while giving the user nothing in return other than the ability to use their product, is one way of going about things. I don’t know if there’s any actual term for this type of “consent,” but for the sake of the blog, let’s call it “consent by acquiescence.” The vibe is, “This seems kinda messed up, but whatever, dude, if that’s what it takes.” Leaves a different taste in the mouth than the proposed alternative: “Hey, we’d like to use data a, b, & c for use cases x, y, & z. We’d like to use this data indefinitely, but each month, we can pay you $10, or we can upgrade your subscription to the paid version at no other cost. Oh, and you can opt-out whenever you want.” This is an informal encapsulation of the mytiki (here’s my biz plug) ethos: data is valuable. Businesses should be able to use data, but only if they get consent from the user. That is covered by most laws. But the kicker is, hey, instead of alienating your user base by monetizing an asset they created without giving them something in return, why not, say, for legally licensing their data to you? This turns the data into zero-party data--data willingly given to a business with the expectation of something of value in return. give them something in return We built technology to make this very thing possible. You can check it out at if you’re so inclined, but let’s focus our attention more on the logic behind why this model is the most intuitive. mytiki.com It’s Legal, but It’s About True Ownership, Not Fine Print The concept of zero-party data licensing is straightforward but game-changing in its execution. Unlike the all-too-common, lengthy terms of service agreements that users scroll through and accept without a second thought, zero-party data licensing is about empowering the user. It recognizes that the data created by individuals is their property — and that any use of this data by businesses must be both legal and fair. What distinguishes data licensing from the “we-own-your-content” clauses hidden in the small print is the principle of ownership. Here, the user is not a passive participant but an active owner of their data. This means the data is not just observed or collected without explicit consent (as with first-party data), but it is owned and controlled by the individual. The mechanics of a zero-party data license also significantly bolster its legitimacy. Participation is entirely optional; users retain full access to the app or website regardless of their choice to license their data. They are not sneakily enrolled but must make an active decision to participate. Moreover, the compensation is not vague or promised in the form of intangible rewards; it is explicit and tangible. This could be in the form of a cash payout, discounts, loyalty points, or other concrete rewards. Zero-party data licensing agreements are immutable and digitally signed by both the user and the business, ensuring that the terms are enforced and protected. The user's ownership is not only recognized but respected and rewarded, making the process of data monetization transparent and equitable. When users are dealt with in the data economy, businesses can foster trust and loyalty. Why hide behind complex legal jargon when you can forge a partnership with users based on respect for their data rights and clear, mutual benefits? There are all sorts of legal questions that arise when it comes to monetizing data. Many are solved with user consent, and user consent is much more likely when they’re getting something of real value in return. If you’re sitting on data you can’t sell or are looking to source monetizable data in a way that genuinely interests users, zero-party data licensing is the best way to do it. In summary: It’s legal. But not in a Reddit-hired-some-lawyers-to-write-something-to-ensure-they-can-use-everyone’s-data-for-whatever-they-want type of way. It deals with users to monetization. It’s data, after all. their It allows businesses to create trust and loyalty by rewarding users and sticking to the actual terms of the agreement. It’s specific. It allows data to be utilized to its full potential with value-adds for everyone involved. Conclusion The Reddit-Google $60 million handshake shines a light on data monetization as a viable means of opening new, recurring revenue streams. The user data market is growing quickly. The rise of privacy initiatives coupled with growing user awareness of the value of their data brings about an obvious fork in the road when it comes to the way we as businesses use and monetize data: we can make slight modifications to the ways of old by baking a data ultimatum into terms of service agreements, or we can move toward strategies that directly involve and compensate the users generating the data. User data will continue to generate interest from buyers in many fields, including the obvious cash cow of training AI. Product-led businesses are missing out on opportunities to add to their revenue by neglecting the potential for data itself to become a viable product. Zero-party data licensing is a novel but logical strategy for turning user data into revenue while building a loyal user base. Take the story of Morrissey_99s and folks like them; it really hits home that users want to be recognized for their contributions. This isn't just about finding some middle ground; it's about coming up with totally new ways that respect what users bring to the table while also making business sense.

How to Monetize User Data Like Reddit (Without Being Sketchy) 

Power users drive some of the most successful companies — people who love their product, are highly engaged, and contribute a ton of value to the network. In ecommerce marketplaces it’s power sellers, in ridesharing platforms it’s power riders, and in social networks it’s influencers. The importance of power users All companies want more power users, but you need to measure them before you can find (and retain) them. While DAU/MAU — dividing daily active users (DAUs) by monthly active users (MAUs or monthly actives) — is a common metric for measuring engagement, . it has its shortcomings Since companies need a richer and more nuanced way to understand user engagement, we’re going to introduce what we’ll call the “Power User Curve” — also commonly called the activity histogram or the “L30” (coined by the Facebook growth team). It’s a histogram of users’ engagement by the total number of days they were active in a month, from 1 day out of the month to all 30 (or 28, or 31) days. While typically reflecting top-level activity like app opens or logins, it can be customized for whatever action you decide is important to measure for your product. The Power User Curve has a number of advantages over DAU/MAU: It shows if you have a hardcore, engaged segment that’s coming back every day. It shows the variability among your users: some are slightly engaged, whereas others are power users. Contrast this with DAU/MAU: it’s a single number and so blurs this variance. When mapped to cohorts, Power User Curves let you see if your engagement is getting better over time — which in turn helps assess product launches and performance of oher feature changes. Power User Curves can be shown for different user actions, not just app opens. This matters if the core activity that matters for your product is deeper in the funnel. In other words, while the DAU/MAU gives you a single number, the Power User Curve gives entrepreneurs several avenues of analysis to assess their product’s engagement to the most addicted users — in a single snapshot, over time, and also in relation to monetization. This is useful. So how does it work? The Power User Curve will “smile” when things are good The shape of the Power User Curve can be left-leaning or smile-like, all of which means different things. Here’s a smile: The Power User Curve above is for a social product, and shows the characteristic smile shape that indicates there’s a group of highly engaged users using the app daily or nearly daily. Social products with frequent user engagement like this lend themselves well to monetization via ads—there’s enough users returning frequently that the impressions can support an ad business. Remember that Facebook would have a very right-leaning smile, with 60%+ of its MAUs coming back daily. What matters is that, over time, the platform is able to retain and grow its power users: successive Power User Curves should ideally show users shifting over more to the right side of the smile. As the density of the network grow, and with stronger network effects, it’s expected that there’s more reason for users to return on a daily basis. Let’s look a different example, which doesn’t smile: The Power User Curve can show when strong monetization is needed This Power User Curve of a professional networking product looks quite different than that of a social product. It’s left-weighted with a mode of just 1 day of activity per month, and decays rapidly after those few days. There’s no power users. But this light engagement can be okay — not every company needs to have a smile-shaped Power User Curve, just as not every product category necessarily lends itself to an ultra-high DAU/MAU. When there’s low engagement, what matters is that the company has a way to extract enough value from users when they areengaged. Think about an investing product like Wealthfront or networks like LinkedIn — few users are likely to actively check it on a daily basis, but that’s ok, since they have business models that aren’t tied to daily usage. CEOs of such companies should therefore,think about: Is there a way to create revenue streams where the business can still monetize effectively despite users’ infrequent engagement? Or, who are the users using this product more frequently, and how can I get more of them? Is there something about the product — e.g. onboarding, the core experience, etc. — where a significant chunk of the user base isn’t experiencing the ‘aha moment’ that makes them “get” the product, and therefore not getting value from it right now (and if so how to get there)? Some products should be analyzed in a 7 day timeframe – like SaaS/productivity – and others on 30 days Another flavor of the Power User Curve is a histogram of users’ engagement for a 7-day period, also commonly called L7. The 7 day Power User Curve shows weekly actives, not monthly actives. Plotting this version can make sense if your product naturally follows a weekly cycle, for instance, if it’s a productivity/work-related product that users engage with Monday through Friday. B2B SaaS products will often find it useful to show this version, as they want to drive usage during the work week. Note that using DAU/MAU wouldn’t be the appropriate metric for this product as it’s not designed to be a daily use product. You can also see there’s actually a smile curve through 5 days, but fewer users are using it 6-7 days, which makes sense for the power users of a workweek product like this. CEOs of such product companies should therefore want to understand: Who are the users engaging just 1 or 2 days each week? Are there certain teams or functions within an organization that are getting more value, and how can I build out features to capture the teams with less engagement? Or, if the product is really driving a lot of value for specific departments — how can I understand their needs better and make sure we continue building in a direction that supports their daily workflow (and that we can upsell new features)? Plotting the Power User Curve for different WAU or MAU cohorts can also be very insightful. Over time, you can see if more of your user base are becoming power users, by seeing the shift towards higher-frequency engagement. The trend of over time can show if the product is getting more engaging over time Here’s an example: The Power User Curve for MAU cohorts from August through November shows a positive shift in user engagement, where a larger segment of the population is becoming active on a daily basis, and there’s more of a smile curve. You can see when the line starts to inflect in order to see when a critical product release or marketing effort might have started to bend the curve.  This might be a place to double down, to increase engagement. For a network effects product, you might expect to see newer cohorts gradually improve as you achieve network density/liquidity. On an ongoing basis, you can measure the success of product changes or new releases by looking at different cohorts’ Power User Curves. If a product unblocks a bunch of features for power users, you might see a gradual increase in power users. The frequency histogram can be keyed on actions beyond the visit — did someone show up or not — you can also go with deeper user actions. For instance, you may want to plot the core activity that maps closely to how your business is monetized… or that better represents whether users are getting value from your product. This is important because it forces you to think about what really matters to measure. The Power User Curve can be based on core activity, not just app opens or logins The above chart for a content publishing platform shows the total number of days in the month users posted content. A lot of products have smile-shaped core activity Power User Curves, because while most people tend to contribute lightly, there is a small contingent of users who are power users. Think of the distribution of Youtube creators, or Ebay sellers, or even how often you post on Facebook. As the CEO or product owner of a platform like this, it’s important to design the platform such that the everyone has a chance to succeed. On Facebook, the news feed algorithm makes sure that if you feel strong affinity to a person or organization, you’ll still see their posts even if the sheer volume of other content (for instance, from more prolific media companies) would otherwise drown it out. On OfferUp, even if I seldom sell items, when I do list something, their algorithm makes sure that it’s surfaced to the relevant potential buyers. Not everything is a daily use product, and that’s okay. Why does this all matter? Power user analysis allows you to get a better understanding of how users are engaging with your product, and make more informed decisions using that data. That might mean choosing an appropriate business model that works for your pattern of engagement, or designing better re-engagement loops for lower-engaged user segments, or doubling down on use cases that your high-engagement user base is already getting value out of. The beauty of the Power User Curve over DAU/MAU is that it shows heterogeneity among your user base, reflecting the nuances of different user segments (and therefore what drives each of those segments). Creating versions of Power User Curve by various user segments can also be particularly insightful. For instance, for a business with local network effects (like Uber or Thumbtack), showing Power User Curves by market can reveal which geographies are developing density and strong network effects. Power User Curves show if your product is hitting a nerve among a super engaged core group of users, even if perhaps the overall blended DAU/MAU is low. It also doesn’t have to just reflect app opens or logins — you can hone in on an action that maps closely to users getting specific value out of your specific product and plot the Power User Curve for that action. The key for founders is to know that there isn’t a single silver bullet to measure perfect engagement — rather, the goal is to find the set of metrics that are appropriate for their businesses. Comparing the Power User Curve of a social app vs. a work collaboration app doesn’t make sense, but looking at your own Power User Curve over time, or finding benchmarks for your product category, can tell you what’s working… and what’s not.

What to Learn from the Power User Curve

While running a self managed elasticsearch cluster like any other database, it's important to make provisions for data backups. Data backups on Elasticsearch can't be done by simply copying elasticsearch data files from one disk to another, this tutorial guides you through making the best use of the Elasticsearch snapshot module for creating cluster snapshots and leverages the Azure blob storage for securely storing your backed up data. Also besides backing up data, the snapshot api also comes in handy for migrating data from one cluster to another. As mentioned earlier, this tutorial uses the as a backup store, other storage services such as Amazons s3 can be used as well, but to follow this tutorial comprehensively you'd need to have an azure subscription, you can sign up for a free trial . You would also need to have access to the Elasticsearch cluster node terminal. Azure blob storage here Moving on... STEP 1 Setting Up An Azure Blob Storage Account follow the steps below to create an azure blob storage account, if you don't have one already for this purpose. 1. On the Azure portal, click on the storage accounts link on the sidebar, or you can use the search resource option to search for "storage account" if this link isn't present on your side bar 2. Click on add new at top left corner of the storage account panel 3. Fill in the required information on the first panel, your can accept the defaults for the next sections, and then create your storage account. 4. Access your just created storage account and create a new container 5. on your storage account page, on the side bar click on "access keys", copy the account name and they key1. That's it for the storage account setup, we then proceed to the next step STEP 2 Installing The Azure Repository Plugin For Elasticsearch To start taking snapshots we need to first register a snapshot repository within our elasticsearch cluster, this repository defines where Elasticsearch should store snapshots taken, learn more about it . Remember these repositories could be an HDFS or a cloud storage service and in this case we are using  the Azure blob storage service. here To register the repository for azure, ssh into your ES cluster node and enter the following commands sudo bin/elasticsearch-plugin install repository-azure If this doesn't work, then try the command below. The bin folder may differ depending on how your elasticsearch was setup sudo /usr/share/elasticsearch/bin/elasticsearch-plugin install repository-azure Afterwards restart your elasticsearch cluster sudo systemctl restart elasticsearch Next, hit the following endpoint to confirm the plugin is installed, , you should get the following output, an object containing details of installed plugins on that cluster. http://eshost:port/_nodes?filter_path=nodes.*.plugins after confirming the plugin is installed, the next step is to setup the plugin to work with our storage account, we'd be configuring the plugin using the storage account name and key bin/elasticsearch-keystore add azure.client.default.account enter your azure storage account name here, next bin/elasticsearch-keystore add azure.client.default.key enter your account key here, if you have issues running these command you should confirm the location of your elasticsearch bin folder, you could try this path , it depends on your installation configuration. After setting the values in the keystore, restart your elasticsearch cluster. /usr/share/elasticsearch/bin/elasticsearch-keystore sudo systemctl restart elasticsearch Next, we set up a snapshot repository, you can do this by sending a post request to the following endpoint and pass the these json payload http://eshost:port/_snapshot/name-of-your-repo { : , : { : , : , : , : }
} "type" "azure" "settings" "container" "backup-container" "base_path" "backups" "chunk_size" "32MB" "compress" true you can leave the type as is, in the settings, the container name should be the name of the container created in your storage account, the defines a folder where snapshot data should be stored, this is useful if you are taking snapshot of different indices or even data from different clusters and storing them in one container. base_path The defines how small big files can be broken down to prior to being transferred . you can get more details about the settings by following this . Below is a screenshot of my settings chunk_size link You should get an "acknowledged: true" as a  response. You can view all your registered repositories by making a get request to the following endpoint http://eshost:port/_snapshot/ Step 3 Taking Actual Snapshots Now let's move on to taking actual snapshots, for this I've created a sample index "sample_records", we could back this up or better still let's back up all indices in the cluster along with the clusters settings.  To do this, make a post request to the following endpoint http://eshost:port/_snapshot/azureblob_backup/%3Csnapshot-%7Bnow%2Fd%7D%3E with the following payload { : , : , : , : } "indices" "index_1,index_2" "ignore_unavailable" true "include_global_state" true "partial" true By default, when option is not set and an index is missing the snapshot request will fail. By setting to false it’s possible to prevent the cluster global state to be stored as part of the snapshot. By default, the entire snapshot will fail if one or more indices participating in the snapshot don’t have all primary shards available. ignore_unavailable include_global_state This behaviour can be changed by setting to true. This is from elasticsearch's official docs . Below is a snapshot of my backup request, partial here Here, notice I didn't didn't add the indices parameter, when the indices parameter isn't included, all indices present in the cluster is going to be included in the snapshot. Take note of the snapshot name / this is the url encoded version of this this is translated to the current date the snapshot was taken, i.e also note that it isn't a prerequisite to name your backups this way, you can give it any name you want to, this just makes sense in case you are doing daily or weekly backups via cron for example, to be able to reference snapshots easily. %3Csnapshot-%7Bnow%2Fd%7D%3E, <snapshot-{now/d}>, /snapshot-2020.04.09, Next, we are going to monitor the status of an ongoing snapshot,  to do this, send a get request to the following endpoint, , http://eshost:port/_snapshot/azureblob_backup/<snapshot-name> note that using the url encoded format won't work if you used it to save your snapshot, instead use the literal string, e.g now http://eshost:port/_snapshot/azureblob_backup/snapshot-2020.04.09, you should get the following response. { : [
        { : , : , : , : , : [ ], : , : , : , : , : , : , : , : [], : { : , : , : }
        }
    ]
} "snapshots" "snapshot" "snapshot-2020.04.09" "uuid" "OjLZEfXDS-mKVqsSi7VteQ" "version_id" 6080399 "version" "6.8.3" "indices" "sample_records" "include_global_state" true "state" "SUCCESS" "start_time" "2020-04-08T09:53:47.926Z" "start_time_in_millis" 1586339627926 "end_time" "2020-04-08T10:03:15.361Z" "end_time_in_millis" 1586340195361 "duration_in_millis" 567435 "failures" "shards" "total" 15 "failed" 0 "successful" 15 Take note of the " array, this shows the names of backed up indices, the state shows the current status of the snapshot it can be either , IN_PROGRESS, FAILED, SUCCESS or PARTIAL, if the snapshot is in a PARTIAL state, it means some indices could not be backed up, the names of these indices are saved in the array. indices" "failures" Now, lets check our azure storage to see if the snapshot was saved in our container. There we go! a snapshot of our entire cluster! Restoring A Snapshot This assume you a new empty cluster you wish to copy your snapshot data to, first on your new cluster you have to configure the Azure repository plugin by following the same steps above, use the same Storage account as that which was used to take the snapshot, keys and all. Ensure also that the matches that which was used in creating the snapshot. Next, send a post request to the following endpoint to restore your snapshot to the new cluster, base_path http://eshost:port/_snapshot/<repo-name>/<snapshot-name>/_restore Note that there compatibility requirements for backups, below are the compatibility ranges If you plan to export data from one ES cluster to another, you need to be aware that not all versions may be compatible with your exported data. A snapshot of an index created in 6.x can be restored to 7.x. A snapshot of an index created in 5.x can be restored to 6.x. A snapshot of an index created in 2.x can be restored to 5.x. A snapshot of an index created in 1.x can be restored to 2.x. Conversely, snapshots of indices created in 1.x be restored to 5.x or 6.x, snapshots of indices created in 2.x be restored to 6.x or 7.x, and snapshots of indices created in 5.x be restored to 7.x or 8.x. This is from the official elasticsearch docs. cannot cannot cannot Bonus! Automating Things The most popular use case of the Elasticsearch snapshot module is for making backups of your cluster and more often than not backups are automated. So I've written a simple node script that helps take a snapshot of your cluster and sends a mail notification on the backup status, this script can be triggered by a cron job set to run daily or however frequently you'd like. axios = ( ) nodemailer = ( ); transporter = nodemailer.createTransport({ : , : { : , : }
}); SNAPSHOT_URL = CLUSTER_NAME = ; dateObj = (); month = dateObj.getUTCMonth() + ; day = dateObj.getUTCDate(); year = dateObj.getUTCFullYear(); hour = dateObj.getUTCHours(); minute = dateObj.getUTCMinutes(); seconds = dateObj.getUTCSeconds(); backuptime = ;



axios.post( ,{ : , : }).then( { .log(response.data.accepted) (response.data.accepted === ){ .log( )
                checker();
            } { .log( )
                notify( )
            }

        },(error)=>{ .log( , error)
            notify( )

        }); checker = { intervalId =  setInterval( { .log( )
           axios.get( )
                .then( { status = response.data.snapshots[ ].state; .log(status); (status === ){ clearInterval(intervalId);
                        notify( )

                    } (status === || status === ){ clearInterval(intervalId);
                        notify( )
                    } (status === ){ clearInterval(intervalId);
                        notify( )
                    } { }
                })
                .catch( { .log( , error)
                    clearInterval(intervalId);
                })
        }, );

  } notify = { mailOptions = { : , : , : , : message
        };
  
       
        transporter.sendMail(mailOptions, (error, info)=>{ (error) { .log(error);
            } { .log( + info.response);
            }
        });
} milisecConvert = { hours,minutes;
        hours = .floor(milisec/ / / );
        minutes = .floor((milisec/ / / - hours)* ); minutes > ? munites : ;

You can and should set up a cron to run this script at specified intervals. axios nodemailer NOTES Elasticsearch snapshots are incremental, that is if a record already exists in the snapshot it wouldn't be part of the next snapshot. This makes the snapshot process run a lot faster especially after the first run. If you do setup a cron for your snapshots, you should take into consideration of how often your data changes or increases while setting intervals. Did this help? let me know. O dabọ ✌

Utilizing the Elasticsearch Snapshot Module for Databackups on Azure blob Storage

Onboarding is the process of making active customers out of users of your product or service. For a company to be able to win new customers, its onboarding process must be top-notch. And in a world where fail, being among the succeeding 10% would take extra effort. one can expect up to 90% of cryptocurrency startups to The same principles guide the various onboarding processes across the board. But an emphasis on cryptocurrency is necessary because of its uniqueness. Despite the now-growing popularity of digital currencies, many still don’t know how they work because of the complex nature of cryptocurrency and blockchain. It should be noted that when it comes to onboarding, the organization can only have guiding principles but not hard rules. That’s because each company is unique in its own way and has to adapt its strategies to its areas of strength. Here are 10 principles to help businesses easily convert traffic to converts and sales. Simplicity The typically complicated nature of cryptocurrency and blockchain is a turn-off for many and has slowed adoption. Therefore, cryptocurrency platforms, especially a crypto platform that offers revolutionary solutions to businesses, investors, and individuals, will have a great edge if it focuses on simplicity. This is not just about simplicity in design but in the overall process of using the platform. New users should not feel overwhelmed when they come across your product else they will leave. Customer is King In planning an onboarding process, use one that is well-tailored to the users’ needs. You may determine this by using different methods of analytics and also tracking customer actions on your platform. When it comes to cryptocurrency, people really just want to buy and sell the currency. Anything that doesn’t meaningfully contribute to that is mere garbage. Active Research and Analytics Before you begin planning onboarding at all and, perhaps, wasting your efforts, it is good to spend a great deal of time doing some market research. Determine the kind of environment and market that ensure the growth of your product. Learn about potential customers’ needs. Find out things your competitors are doing wrong and make those your selling points. Even after kick-off, perform analytics to know which actions lead to the conversions and if a change is necessary. Not knowing that is one of the . onboarding mistakes to avoid Show and Tell Onboarding is not just to get users to start utilizing your product; it is to show them how in a simple and non-intrusive manner. Instead of which are boring and arduous, short video tutorials and animations would be better to effectively explain all you want to. too many screen-by-screen walkthroughs You know how valuable your product is and what it does, but the real question is: do your customers? Educate For a cryptocurrency platform, it is important to build your onboarding around ensuring that new users are quickly acquainted with the services you offer. While you will have many pro new users, consider that a significant chunk of your user base would consist of cryptocurrency newbies. Therefore, build your onboarding around educating them about the functions of your platform. That is the more reason why you have to keep onboarding very simple. Engage with your Users Onboarding should not be a process that is just about the organization alone. The user too should be actively involved. While showing and telling, asking the users to repeat the processes explained would make for a better experience. Form a Forum Communities (including online ones) are very good. You can create a network of people who use your trading platform and give them an avenue to discuss, seek help, and banter. Online forums give people a sense of belonging and makes users more likely to stay on as lifetime customers. Personalize it If there were a perfect onboarding process, it still wouldn’t sit well with every single user of your product. As a result of that, it is important to make the experience unique and personal for each person. That doesn’t mean creating a different onboarding process (really?) It means ensuring that the process leaves some impact on the user. You surely know what they say about first impressions. Make sure you know your customers. Top executives like the importance of making onboarding personalized. Matt Sornson recognize Request Feedback And yes, it still works. But as mentioned earlier, keep things simple and short. Don’t make your customers start feeling they are sitting for an examination when you give them a lengthy list of questions. You may trigger them to rate your product and leave a review but be sure it is also in a non-intrusive manner. Selling Points Structure your selling point about how trading with you would help the customer. No one really wants to know what your software can do if its features won’t eventually be of help to them. This tweet by Jason Fried of Basecamp years ago sums it up: Conclusion Many make the mistake that onboarding ends when a user signs up for a paid subscription of your product. That is somewhat true, but ignoring everything after that is a disaster. Even after signing up, onboarding still continues and you owe them good treatment. Customer is king, right?

10 Things to Note Before Onboarding on any Cryptocurrency Trading Platform In 2019

With hardware updates not making headlines like they used to, Apple has spent the last year attempting to dominate tech news, instead, with announcements of a range of new privacy protection features and policies. The most significant of these is without a doubt App Tracking Transparency (or ATT for short), a part of the iOS 14.5 update. Receiving an updated dashboard in iOS 15, ATT appears to the user as a simple pop-up message whenever a mobile app is opened for the first time. In the message, users are asked if they would like to allow the company behind the app in question to track their activity and access their data. At no additional cost to them, the user can say 'no.' This represents a groundbreaking change in Apple policy and - unsurprisingly - users are opting out of tracking in droves. Globally, as many as 90% of iPhone users have already chosen to disallow apps from collecting and storing their data. While this has been hailed as great news by privacy activists, companies in many data-driven industries have begun to express concern. Perhaps the loudest outcry has been heard from digital marketers and the platforms on which they rely. The Challenge for Social Media Each year, social media platforms like , , and generate more than 150 billion dollars of revenue from advertising. Most of this success owes itself to the data these companies collect from users. Facebook Twitter TikTok With easy access to data over the last few years, a business model has arisen in the digital space that involves the application of to the personal information of users. Social media platforms package these technologies as easy-to-use advertising tools, usually sold using a cost-per-impression or cost-per-click model. Businesses and digital marketers use these tools to create highly-tailored advertisements which target specific segments of the platforms' user bases. AI and machine learning Given that iOS users make up a huge chunk of social media's user base, one might wonder: Will large digital platforms still be able to sell their advertising products going into the future? Finding Workarounds As the saying goes, “necessity is the mother of invention,” and several major platforms have already announced plans to get around the new restrictions placed on them by the ATT feature. The most notable of these workarounds are being implemented by market leader , which generated about 84.2 billion dollars in advertising revenue in 2020. Facebook Facebook's approach is to 'depersonalize' all data that they collect using encryption. Basically, after being processed by the company's so-called "Privacy-Enhancing Technologies," the data remains analyzable by AI but becomes untraceable to any particular user. This, Facebook hopes, is in with both and . compliance GDPR Apple policy Although this solution has only recently been implemented, it does seem to have a good shot at keeping AI/ML technologies at play in the digital marketing space. As of the time of writing, Facebook's solution still has yet to be shut down by Apple. The same can't be said about somewhat to track users by ' ' their devices... TikTok's nefarious attempts fingerprinting Digital Marketing and AI in 2022 (and Beyond) So far, a few key trends have emerged, providing a decent glimpse into how things could look for advertising and AI in the coming years. First, there can already be observed a clear shift among marketers away from quantitative metrics and towards qualitative ones. Ads are no longer being created just to target specific demographics, but instead to have greater mass appeal. As such, companies are not focusing on the micro-level, but on the macro — on things like overall customer satisfaction and gross sales. Of course, AI will continue to be applied to this data to help make informed decisions about campaigns. Second, it is now clear that with fewer ways to target customers on a personal level, digital marketers will need to experiment with other variables. One example of a non-personal variable that can be analyzed is the number of conversions per ad against the time that the ad had been published. Digital marketers may want to experiment with automating the publication of ads, so that they can be put out at the ideal moment. Neural networks that can predict the best possible publication times are set to become a go-to tool. Other 'depersonalized' variables could be things like ROI, ad spend, and the number of likes on a post. Finally, digital marketers are already applying the lessons they learned over the last few years of AI-powered predictive advertising to tried and tested marketing strategies like gated offers, loyalty programs, and email marketing. A very simple example of such a campaign would be to put out an ad offering a coupon code in exchange for filling out a survey and leaving an email address. This, in effect, represents an 'opt-in' on the part of the user. Any data that is willingly shared can be used without qualms. Data-Driven Advertising Is Just Getting Started If one thing seems certain today, it's that privacy stands to be one of the chief driving forces behind the next era of digital marketing. Yes, at times it may seem a pesky restriction, but ultimately it is only through overcoming obstacles that innovation can be achieved. We know this from experience.
