Hi, I have a Cassandra 2.1 cluster running on AWS that receives high read loads, jumping from 100k requests to 400k requests, for example. Then it normalizes and later cames another high throughput.
To the application, it appears that Cassandra is slow. However, cpu and disk use is ok in every instance, row cache is enabled and with almost 100% hit rate. The logs from Cassandra instances doesn't have any errors, nor tombstone messages or something liked that. It's mostly compactions and G1GC operations. Any hints on where to investigate more?
