Before you start to claim the performance numbers of your Cassandra backend based on numbers that you have read elsewhere, it is important to perform your own stress testing. It is very easy to do that in Cassandra as it provides special tooling for stress testing. It is a good idea to customize the parameters of the stress test to represent a use case that is closer to what your application is going to do. And this will save a lot of heated discussion later due to discrepancies in the load test and the actual throughput that the software is able to pull out of the setting.
The load test tool is found under the Cassandra installation directory under tools as tools/bin/cassandra-stress
. Here are some useful parameters:
-d, --nodes: CSV list of nodes to run the queries against-o, --operation: Operation to perform, default: insert-R, --replication-strategy: Replication strategy, def: Simple-O, --strategy-properties: in <dc>:<RF>,<dc1>:<RF1> format-U, --comparator...
