Performance Tuning A Streaming Application

Mathieu Dumoulin explains how he was able to get 10x performance out of a streaming application built around Kafka, Spark Streaming, and Apache Ignite:

The main issues for these applications were caused by trying to run a development system’s code, tested on AWS instances on a physical, on-premise cluster running on real data. The original developer was never given access to the production cluster or the real data.

Apache Ignite was a huge source of problems, principally because it is such a new project that nobody had any real experience with it and also because it is not a very mature project yet.

I found this article fascinating,¬†particularly because the answer was a lot more than just “throw some more hardware at the problem.”
