Subject Re: Cassandra Multi DC (Active-Active) Setup - Measuring latency & throughput performance
Date Fri, 26 Feb 2016 23:31:25 GMT
Hi Chandra,

For write latency, etc. the tools are still largely the same set of tools
you'd use for single-DC- stuff like tracing, cfhistograms, cassandra-stress
come to mind. The exact results are going to differ based on your
consistency tuning (can you get away with LOCAL_QUORUM vs QUORUM?) and
read/write patterns.

What other data are you looking to gather?
