After hosting the Meta Refresh Delhi Runup Event, it was time for us at Wingify to prep up for MetaRefresh. We were very excited to contribute back to the community by not just sponsoring MetaRefresh, but also by adding content to the conference through a talk and a workshop, both focused towards Web Performance.

We started off our journey from Delhi to Bangalore on 15th May, a day before the conference, and were welcomed by awesome weather at Bangalore. We took off early the next morning and grabbed our bags to march towards MLR Convention Centre, Bangalore to setup our company booth. The setup didn’t take much time, and we were ready to welcome fellow attendees to share more about Wingify through our stall.

While speaking to the attendees, many expressed their interest to get interviewed at Wingify. Usually, we redirect the interested candidates to mail their resume to [email protected] and follow the procedure, though this time, we gave it a unique touch, while using a Hack developed by Paras (our Founder & CEO), on a hack night. It was a mystery containing different hints that lead to the next clue, solved using browser’s developer console. It was great fun to watch attendees trying their best to crack the hints and unravel the mystery, though only few were able to solve it.

Some moments captured during Meta Refresh 2015:

A generic issue discussed in majority of the talks was regarding the maintenance of mobile web version of businesses after the successful creation of native apps on most popular mobile platforms. Several supporting /contradictory arguments were made with regard to this topic, though the most logical were in favor of supporting mobile web version as well. Several speakers shared their experience of the efforts involved in maintaining the web version or making the web experience as great as the one delivered through the native apps.

Performance was another major topic discussed in several talks, involving not just the networking performance of web applications, but also the rendering performance as well. Another big discussion revolved around achieving jank free performance while performing animations in not just the web applications, but games as well. Several techniques and approaches were discussed in the talks that shared the experience of speakers on the quest to achieve 60fps in web applications.

We had a great time being part of MetaRefresh 2015, and look forward to more such events, so stay tuned with our different social media channels (Twitter, Facebook) to meet us at another conference.

Giving back to the community has always been a priority at Wingify, be it through open sourcing internal projects or via organizing / sponsoring community events, the most recent being Meta Refresh Delhi Run-up Event organized and hosted by Wingify on 21st March 2015. Tony Simon from HasGeek was present from the MetaRefresh Team to help us host this event and help us make it more awesome.

Siddharth Deswal speaking on “How to Communicate Better with Marketing, Sales and Other 'Business' Types”

The event started on time (10:30am) with Tony introducing MetaRefresh, HasGeek and Wingify to the attendees. Siddharth Deswal, Marketing Guru at Wingify kickstarted the event with his talk on “How to Communicate Better with Marketing, Sales and Other ‘Business’ Types”, along with shots of humour. The talk started with the narration of his own experience of wearing different hats at Wingify with him helping different departments. He concluded on a great note saying that different departments shouldn’t be isolated and must focus on sharing and imparting knowledge to people from other departments, especially the ones who are interdependent; the best example being that marketing team should also try to understand the technical aspects related to feature development.

Apoorv Saxena describing browser evolution in his talk on “Hacking to be Performant?”

A pure technical talk related to web performance, started off with a poll to find out how many of the participants measure performance regularly and have it part of their deployment process, the feedback from the attendees depicted negligible measures taken to continuously monitor product performance. Next was the discussion of the reasons on why performance mattered, which was followed up with the discussion of various hacks that people employed to bring performance to their applications. The core part of this talk discussed the difference between using hacks versus following different approach during development, and how each of them paid in the long run.


Vipul Taneja speaking on “Landing Pages Optimization”

Next talk was presented by Vipul Taneja from AdSparkx media on “Landing Pages Optimization - Things you can do to ‘Test’”, with him briefing the attendees about his visit to Vegas and his observance about it during that time. His talk comprised of various techniques that his company uses to maximize ROI on different landing pages of businesses that hire them. The talk comprised of the discussion of both White Hat and Black Hat techniques as well for increasing landing page conversions.

Taruna Manchanda speaking on “How to optimize your webpages - lessons learnt from 101 VWO customers' A/B tests”

Next speaker was Taruna Manchanda, who shared her experiences and learnings while taking care of all paid acquisitions and customer case studies, as part of the Digital Marketing Team at Wingify. The attendees gathered great insights about how to best A/B Test a webpage along with the focus on what needs to be measured and how.


Saptarshi Chatterjee speaking on “How to automatically generate Tests for your JavaScript file”

Last on the speaker line up was Saptarshi Chatterjee, Technical Lead at McKinsey, presented on “How to automatically generate tests for your JavaScript file”, while introducing his open source project to the world named YoSapy([yeo]man generator + [Sap]tarshi). He started off with the discussion of the importance of test cases and how he came across the idea to automate the test case creation process. He gave a hands-on demo of his project and took the rest of his time out to answer questions from the audience on how easy to have it part of their existing projects and also about how to extend / contribute to the same further.

Performance matters, and an Angular.js developer would especially know it. Several watchers in a digest cycle can often be a bottleneck, and Angular doesn’t recommend having more than 2,000 of them in your application.

We are proud to announce q-directives, a brand new and fast directive system for Angular.js, that takes the watcher optimization to a whole new level. It was a result of several jsperf tests and Chrome Timeline runs.

Q-Directives on Github


VWO is single-page application made entirely in Angular.js. When designing a detailed reporting system for campaigns in Angular.js, we faced troubles with rendering large amounts of data using Angular directives. In one of the report pages, the application had registered 15,000+ watchers, especially due to the way ng-repeat works.

With q-directives and a revamped directive system, the number of watchers for a q-repeat directive (replacement for the ng-repeat directive) was brought down to just 1. So whenever the list changes, only one watcher gets fired.

Performance Benchmarks

Below stats are a rendition of the Chrome (version 37) timeline for the following use case:

A table containing 216 rows repeated by q-repeat. Each row has about 10 columns containing about 50+ Angular directives each (Original). The optimized version has those Angular directives replaced with q-directives, and ng-repeat is replaced by q-repeat.

Data is collected over 5 samples for both Original and Optimized situations.

Elasticsearch is essentially a distributed search-engine but there have been more than one example of companies and projects using Elasticsearch for analytics instead of search. We, at Wingify, had similar requirements when we decided to make our analytics more powerful to empower the customers of our product, Visual Website Optimizer (VWO). This blog post is about how we used Elasticsearch to make VWO’s user tracking a lot more powerful than it earlier was.

The Problem

For context, VWO is a tool that makes A/B testing of websites and mobile apps so simple so that there is no engineering intervention involved to run new A/B testing campaigns. Marketers and UI/UX designers do A/B testing to improve online conversions and sales. VWO helps them with performing these A/B tests with almost no engineering knowledge.

Since VWO is at the center of optimizing websites and mobile apps, this makes user tracking important for our product - our users make use of the data we collect to understand how their users (different segments of users) behave and make optimization decisions accordingly. For example, in an A/B test campaign with three variations, variation 2 might be winning for all the goals but for all the users coming from India, variation 3 might be winning for all or some of the goals. It should be possible for our customers to generate custom segmented reports and observe these different behaviours.

So lets summarize how a campaign and its reporting should work:

  • A VWO customer may create multiple campaigns. These campaigns have more than one variations (variations are variants of web pages or iOS apps with UI changes) that our customer wants to A/B test against real-traffic.
  • Every campaign has more than one goals (goals are events that you want to track, such as visiting a particular page, clicking a DOM element, submitting a form, triggering a custom event with JavaScript etc.) which our customer wants us to track.
  • Our JavaScript library tracks how real visitors trigger goals (events) per variation and sends this data to our data collection end-points.
  • Our data backend stores every visit and conversion for all the defined goals per variation. This is stored on a day-wise basis.
  • When the campaign’s report is accessed, the day-wise visitor and goal conversion data is used in the statistics that go behind generating the report.
  • Reports are generated considering behaviour of all the users who became a part of the campaign. However, our customers should have the flexibility to segment reports on the basis of parameters like location, browser, operating system, time range, query parameters, traffic type, etc.

In the prehistoric times

We used to store only counters in our database (we use MySQL) i.e. for goal per variation, we used to store number of visitors and conversions. Here is some sample data:

| account_id | experiment_id | variation | goal_id | event_date      | hits | conversions |
|          1 |           198 | 2         |       1 | 2011-02-19      |   15 |          12 |
|          1 |           198 | 1         |       1 | 2011-02-19      |   10 |           2 |
|          1 |           198 | 2         |       1 | 2011-02-20      |    6 |           2 |
|          1 |           198 | 1         |       1 | 2011-02-20      |   13 |           8 |
|          1 |           198 | 1         |       2 | 2011-02-21      |    7 |           0 |
|          1 |           198 | 1         |       1 | 2011-02-21      |    7 |           7 |
|          1 |           198 | 2         |       2 | 2011-02-21      |    8 |           0 |
|          1 |           198 | 2         |       1 | 2011-02-21      |    8 |           8 |
|          1 |           198 | 2         |       2 | 2011-02-22      |    6 |           0 |
|          1 |           198 | 1         |       1 | 2011-02-22      |    8 |           8 |

We also support revenue tracking for a goal. There is a different table for revenue tracking, which looks something like this:

| account_id | experiment_id | variation | goal_id | event_date      | revenue |
|          1 |           198 | 2         |       1 | 2011-02-19      |   32.43 |
|          1 |           198 | 1         |       1 | 2011-02-19      |   34.35 |
|          1 |           198 | 1         |       1 | 2011-02-19      |    6.13 |
|          1 |           198 | 2         |       1 | 2011-02-19      |   21.93 |
|          1 |           198 | 2         |       1 | 2011-02-20      |   83.36 |
|          1 |           198 | 2         |       1 | 2011-02-20      |   72.65 |
|          1 |           198 | 1         |       1 | 2011-02-20      |   56.14 |
|          1 |           198 | 1         |       1 | 2011-02-20      |   87.12 |
|          1 |           198 | 1         |       1 | 2011-02-21      |   78.25 |
|          1 |           198 | 1         |       1 | 2011-02-21      |   88.36 |

So when our customers want to view the report, our application’s backend will run some queries to generate aggregated metrics like total visitors per goal per variation, total conversions per goal per variation, etc. which could be taken care of using MySQL’s built-in functions and then do some statistics at the application level to decide winning variations per goal.

Notice that in our first table where we store hits (visitors) and conversions, we store total counters of these two metrics per goal per variation per day. In the revenue table, we store every individual revenue per goal per variation with the exact date they occurred on. We need these separately as we need to calculate sum of squares of every revenue generated which is used in the statistics. I am not going to delve in the statistics side of things because that is out of scope of this article.

This worked pretty well for us for a while. It was all very simple and we had to deal with aggregated data most of the times other than the case of revenue where in we had to get every row of revenue for a particular campaign. At the application level, it was essentially firing up a few MySQL queries that would give us the aggregated and day-wise data and then use that data to statistically find winning variations per goal.

But this setup had a major drawback. Our customers were restricted to the view of reports we would expose them to. It was not possible to drill down and understand how different segments of users are behaving as the complete picture may not say it all about some different segments. For example, in an A/B test campaign with three variations, variation 2 might be winning for all the goals but for all the users coming from India, variation 3 might be winning for all or some of the goals. Finding this out was only possible by running another campaign targeted to users from India on the basis of a hunch to understand if the results would differ. And many times the results would not differ and our customers will lose visitors from their visitor quota.

Furthermore, our data storage had a few other problems like no fine grain control over date and time range (it was all day-wise), we would store all the counters according to our customers’ timezone (set at the time of account creation) which means that changing timezone later would be possible but the data collected earlier would be shown according to the previously selected timezone. These were some major drawbacks to our way of storing visitor and conversion data.

New Age Reporting

We knew that our existing MySQL based setup was not perfect but more importantly we realized that it does not help our customers. We wanted to make things simpler for our customers so that:

  • they could easily find important segments of users that behave differently and run targeted campaigns for them if necessary.
  • they have finer control over date and time so that they can see reports at different steps like months, days, hours, minutes, etc.
  • store everything in UTC so that we can take care of timezone changes at application level.

Looking at our application requirements, we realized that we cannot work with just aggregated data any more. We needed to start storing individual visitor’s data and their corresponding conversions to achieve flexibility and giving the power of slicing and dicing of the data in our customers’ hands.

We are also a pretty small team, which means that we wanted lesser headaches about ops and maintaining the entire system in production. We wanted things to be simple and as self-managed as possible.

Our specific requirements were:

  • Allow storage of individual visitor data with a lot of properties for performing segmentation.
  • Allow filtering on all the stored fields for performing segmentation.
  • Allow full text search on a few fields.
  • Capable of storing events for lifetime of a customer account. This means that we cannot delete visitor data as long as our customer is with us.
  • Getting consumable data out should be fast, or lets say not terribly slow. We are okay with an average of 2-3 seconds to start with.
  • Easy ops:
    • Fault tolerant system. Failing nodes should not bring the service down.
    • Scalable to handle our growing traffic, storage and other requirements.

We knew that Hadoop is the de-facto system in the Big Data universe but the entire Hadoop system is so vast that getting started with it is not as easy. There tons of different tools in the Hadoop ecosystem and just selecting the right tools for your use-case may take a significant amount of time for research, leaving the implementation time aside. Also, running a Hadoop cluster is no piece of cake. There are so many moving parts that you are not completely aware of as soon as you start. And performing upgrades of systems that have more systems running with it will always be problematic. Further, tuning all these systems to give an acceptable performance also seemed like a daunting task for a team as small as our’s with no prior experience with such systems.

On top of the above problems that we got to know about Hadoop from our friends working with it and from different blogs/websites, the task of implementing the infrastructure requirements for Hadoop, building an implementation, managing in production and then repeating the cycle for a team of 2 engineers seemed like a daunting task.

We knew that life would be much easy if we keep things simple and we started looking at other options.

Elasticsearch to the rescue

Having worked with Elasticsearch before for a smaller project and remembering that I had watched Shay’s talk from Berlin Buzzwords where he mentioned that Elasticsearch was also being used for analytics, we started looking at Elasticsearch to solve our problems.

Elasticsearch supports filtering which we could use to filter visitors and their conversions on the basis of a lot of properties that we wanted to collect for every visitor. Filtering would be fast in Elasticsearch because you can have indexes on every field if you want and since Elasticsearch uses Lucene under-the-hood, we were confident about its indexing capabilities. Elasticsearch supports full text search out-of-the-box. This fits well with our basic application requirements. On top of this, Elasticsearch supported Faceting (when we were evaluating, aggregations frameworks was not there) which we could exploit for analytics. That means we don’t even have to get all the data out of Elasticsearch to our application layer. Elasticsearch is capable of giving us an aggregated view of the data we were storing.

This was just amazing for us. We were able to build a PoC within two weeks. The next couple of months were spent on understanding Elasticsearch better, optimizing our implementation, testing Elasticsearch against production load and tuning it for the same.

In the meantime, Elasticsearch released 1.0.0 with aggregation framework and we quickly moved from using Facets (see Faceted Search) to Aggregations. Aggregations proved to be very useful with revenue goals as we could just ask Elasticsearch to give us sum of squares of individual revenues without getting individual revenues out of Elasticsearch.

As pointed out earlier, we need to track individual users. How we do this is we create a document for a unique visitor per account per campaign in Elasticsearch. This document stores user meta data, data for segmentation and goal conversion tracking data. A typical visitor document looks like this:

   "_index": "february-2015",
   "_type": "123",
   "_id": "D2E0A04858025DFE23928BC1F70D2156_123_313",

      "referrer": "",

      "os": "Windows 7",
      "email_traffic": false

_id is the UUID of the visitor. Most of the other fields have information extracted out from the IP address, the User Agent, the URL and the Referring URL.

All the fields except a few are some fields with their types correctly set. Indexes are maintained on all of them so that visitor documents can be filtered according to the values in these fields.

But there are a few fields that are interesting:

  • query_params
  • converted_goals_info
  • converted_goals_info.facet_term
  • variation_goals_facet_term

Let’s look at each of them one-by-one.

  • query_params is an array of objects for storing query parameters and their respective values. This is of type nested because our customers may want to find all visitors and their conversions who visited pages with certain query parameters. Consider a scenario where you want to find all visitor documents with query parameter param1 and val2. A simple bool must query with term query would return the above document if query_params was not nested because it would find one of the two query_params.param values to be equal to param1 and the one of the two query_params.val values to be equal to val2 but we know that param1 never had val2 as its value. This happens because each object in query_params array is not considered as an individual component of the document. nested types solve this problem. Read more about nested documents and relations in Elasticsearch in this blog post.
  • converted_goals_info is also an array of objects for storing information of individual goal conversions. Here we store goal_id of the converted goal, the time of conversion as a DateTime field and another field that we will shortly discuss. This field is also of nested type for the same reason as with query_params.
  • converted_goals_info.facet_term and variation_goals_facet_term need to be discussed together because their values are constructed in a similar way. They in particular don’t hold any new information. In the beginning of the post, we saw how we used to store aggregated visitor and conversion count per goal per variation per day. We still need that data out of Elasticsearch in a similar way for our statistics. The day-wise problem gets solved by using day-wise buckets in aggregations framework. The next problem is getting visitor counts per variation per goal. In MySQL terms, we would want to run a GROUP BY query on variation and goal_id column. In Elasticsearch, we can do something similar by using Terms Aggregation using Scripts. The problem with this approach is that if you have a large number of documents, your script will get evaluated on all of them and Elasticsearch is not really a script execution engine (no matter which scripting plugin you use). What you can do instead is push the result of a script at the time of indexing and then simply run Terms Aggregation on it. We saw massive performance boost by doing this performance hack.

Every document gets saved under the doc_type for the account that campaign belongs to i.e. every account on VWO has a separate doc type.


From performance point-of-view, Elasticsearch has very fast indexing and querying capabilities. It is a distributed system - you can deploy a cluster of nodes in production which stores indexes in a distributed fault-tolerant way to give you performance benefits. Increase the number of replicas per shard and you can scale reads and queries. This can be done after creating an index as well. Elasticsearch does not allow changing of number of shards though. But there is a sweet work around for that. Just create a new index with more shards and use aliases, and you can now scale indexing as well.


From our experience with working on large data sets which need to be queried on an ad-hoc basis and have low latency requirements and from our learning from Shay’s talks (1, 2, 3), we understood that a data storage system meant to store a lot of data will scale for your reads and querying requirements well if you can shard your data well according to the variable that determines the growth of that data. For example, if you are using any database for storing machine logs, you should be able to shard your data probably according to time because you would want to query the most recent data and if you have to do it from the all the data you ever collected, then your old data will only become a performance bottleneck. So a possible sharding strategy could be sharding data according to month-year.

Our requirement was similar. We get visitor data which we could easily shard on monthly basis. And since this data would keep on growing, we can just add new indexes every month and place the new data in these indexes. However, which index a visitor document goes to is not determined by the timestamp of the visitor but it is determined by the date of creation of the campaign. Why? Our customers view campaign reports i.e. when a campaign report is opened, we want to get data for that campaign only. So it would make sense to have all the data for a campaign reside only in one index because we wouldn’t want to look into multiple indexes for generating report of one campaign. If we decided to put visitor documents in different indexes depending upon time of visit, we would have faced the following problems:

  • A campaign may run for more than a month, so visitor documents for a campaign may be in more than one indexes and we would not have any way to know which all indexes without keeping a track of it separately as to which indexes have visitors for a given campaign. This would be painful.
  • Since visitors also convert goals and we store conversion data in visitor documents, it would be very difficult for us to find which index to find the visitor document in so that we can add conversion tracking related data in the document.

These problems get solved when we restrict all visitor data for a given campaign to go in one index only. So for account_id 123 that has two campaigns - campaign 1 (created in January 2015) and campaign 2 (created in February 2015), the visitor documents for both will be created in the indexes for January 2015 and February 2015 respectively.

Another big advantage of this is that we can adjust the number of shards every month. So if we are seeing a trend of more visitors getting tracked month after month, in the next month we can create a new index with more shards than the previous month’s index.


Since documents are stored in a particular shard in an index, Elasticsearch needs to decide which shard to put the document in. Elasticsearch use a hashing algorithm that is used for shard selection and Elasticsearch uses document’s ID by default for determining which shard that document goes into. This is called routing a document into a shard. This may work fine in some cases. But the drawback of this default routing strategy is felt when you have a large number of shards and also when you have to serve a lot of queries. The drawback is that Elasticsearch now needs to search every shard in an index for all the documents matching a given query, wait for the results, aggregate them and then return the final result. So for a given query, all shards get busy.

This can be controlled by using a better routing strategy. In our case, we generate reports of a campaign of a given account. It would be ideal that one account does not limit report generation of another account. So instead of going with the default routing strategy, we decided to route documents on the basis of account_id. So now, when a campaign report is generated for a given account, the query hits only a single shard, leaving all other shards available for serving other queries and also freeing up CPU resources. After moving to this routing strategy, we saw a significant reduction in CPU usage in our cluster.


From operations and management point-of-view, Elasticsearch is fault tolerant - indexes can be sharded and replicated and distributed in a cluster. Elasticsearch distributes shards and their replicas on different nodes in the cluster so that if a node fails, Elasticsearch promotes replicas to be the primary shards and moves shards and replicas in the cluster to balance the cluster. What is really amazing is that Elasticsearch also gives control over placement of shards in a cluster so that it is easy for you to separate hot data from cold (historic) data easily. We have not had the need to use this feature yet, but it is good to know that we can do this if at all historic data becomes a performance problem. Chances are that it will become a problem but probably much later.


Although Elasticsearch made it really easy for us to push out something like this with so much ease (and remember we had no experience building something like this before) and we love Elasticsearch for that, we did find a few things with it that we think limits us.

  • The facet term hack for avoiding running scripts works great but then it’s also limiting if you want to add new features in your application that rely on different scripts that were not added at the time of indexing. This means that you will have to re-index all your data if you want to support this new feature or just provide this feature on new data.
  • Lack of JOINS becomes limiting. As of now we push the conversion data in visitor document. But it would have been ideal if we could independently index conversions data in a separate index or doc type.

We don’t know how to solve these problems yet or if Elasticsearch team has any plans for bringing something new that fixes these problems. It will open Elasticsearch to a lot more possibilities if JOINS were possible. But we also understand that it’s not a simple problem to solve and Lucene and Elasticsearch were not made keeping these use-cases in mind. Nevertheless, we hope to see these improving in the future, especially because a lot of companies are using Elasticsearch for analytics as well.


Elasticsearch has been great for us and it proves that you don’t always need Hadoop for building analytics depending upon your requirements. The amazing thing is that we feel Elasticsearch is amazing when it comes to scaling when limited by resources - horizontal scaling is extremely simple. But it will work for you or not depends entirely on your requirements.

Elasticsearch already works with Hadoop, which is being further developed to expand the use-cases it can support. This gives us a lot of confidence as we will add more features to VWO’s user tracking in the future and we know that we will not be limited by our decision to use Elasticsearch.

Meta Refresh is an event organised by HasGeek that focuses on design, user experience and the front-end web. The current iteration of Meta Refresh (2015) will be held in Bangalore on April 16-17.

Wingify will be hosting the Delhi run-up event for Meta Refresh. The session will focus on how designers, engineers, optimization specialists and businesses can use data (statistics) to drive design opinion, thereby optimizing their websites and web applications. The premise being that the data speaks for itself at any point of time, and provides you with validations or rejections on your hypothesis. A data-centric approach towards web-design serves the same cause. The design / layout of any website is based on certain intuitions of the designer, and many a times there is a conflict of interests between the designer and the business team. How about tweaking the website to bridge the gap between design and business?

If this is a topic that interests you we encourage you to join us for the run-up even at our office on March 21, starting at 10am. It would be a great opportunity for you to:

  1. Speak - If you have a similar topic in mind, or even a different one that goes with the theme of Meta Refresh 2015 (web in your pockets), propose a session at the talk funnel.
  2. Learn - RSVP for the event at the same link and be present for the event to learn from the community.
  3. Interact - Mingle and chat with us and other attendees about design, usability, or anything at all.

We look forward to seeing you at the event!

Event Time: March 21, 10am - 3pm
