Akka Streams to the Rescue

In this talk, you will learn about the challenges we faced at Credit Karma in our Data Transformation project and the solutions we ultimately arrived at, including:
- The way we transformed several billions of data points stored in MySQL, which gets live updates
- How we ran large volume, CPU intensive data transformations by adapting to available processing headroom without affecting the live load on MySQL. How Akka Streams simplified our implementation of high throughput data flow and processing - with optimized CPU and memory usage. We will also touch on some challenges we faced with Akka Streams.
- Akka Streams don’t cross JVM process boundaries. So, how did we solve this challenge in a distributed environment?
- Finally, we’ll look at some performance numbers on our approach.
You will walk away with implementation ideas and performance numbers to help them design large scale data processing/transformation projects based on Akka streams.
