Eric Evans commented on CASSANDRA-3634: --------------------------------------- Here is the performance comparison. I stuck to the same tests I performed earlier (those earlier results can be found [here|http://www.acunu.com/blogs/eric-evans/cql-benchmarking]). The patches to support binary query parameters for Cassandra and {{stress}} are attached to this issue, and the raw results can be found [here| http://people.apache.org/~eevans/3634]. _Note: Percentages listed are in relation to RPC performance._ h3.
