Data serialization is a very common process in web applications. So common that no one gives it a second thought. You just pull data from the DB, and your server and client frameworks just handle this thing for you. The server serializes the data into JSON, and the client parses it to JS object. This flow is simple and natural but, as everything, when taken to the extreme start to show scaling issues. What is an ‘extreme’ for data serialization? A lot of data. Serializing and deseriazling tens of thousands … Read More
Developers often make mistakes. Bugs go unnoticed, uncaught by unit tests, overlooked by QA and reach production. Sometimes it’s just a minor issue, sometimes it’s major bug that costs you lost data and users’ confidence. Whatever it is, the issue gets fixed. You patch the bug, mend corrupt data and everything gets back on track. Surely there isn’t a bug that is unfixable right? Well, for a while, it seemed like we experienced an unfixable bug. Here’s our story of how we found it, and how we got back on … Read More
Preface When we started Jaco we set up a goal to be able to handle massive amounts of data (for a startup). To do that, we realized our system will need to support hundreds of thousands of events per second. As we started receiving more traffic, splitting up components into different parts started to make more sense as it provided us with an easier way to reason about code and scale different parts of the application depending on specific load.
One of the big challenges in providing a good funnel analysis solution is being able to provide your users with data while not complicating the implementation process. Because of our video session recording capabilities, a lot of our users use Jaco to learn how their users behave within their product and optimize their funnels.
