Understanding Cassandra Code Base

A bit old, but great read. And very useful diagrams:

Reading through the code using a debugger, while running a unit-test is an awesome way to get things into your head. I’m not a huge fan of debuggers, but one thing they are good at is learning a new codebase by singlestepping into unit tests. So what I did was to run the unit-tests while single stepping into the code. That was awesome. I also ran the unit tests for Hector, which uses the thrift interface and spawn an embedded cassandra server so they were right to the point, user friendly and eye opening.

Some time ago, I’ve posted about Cassandra write operation and Cassandra reads performance.
