[jira] [Created] (CASSANDRA-8658) cassandra-stress should support distinct readers/writers for a mixed workload

Benedict created CASSANDRA-8658:
-----------------------------------

             Summary: cassandra-stress should support distinct readers/writers for a mixed workload
                 Key: CASSANDRA-8658
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8658
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Benedict
            Priority: Minor


By default all threads assume they interleave reads with writes, whereas many workloads may be characterised by independent readers and writers. The difference is that by interleaving, if we have hit e.g. disk constraints for flush, write latencies may spike while read latencies are unaffected. By interleaving operations on each actor, all actors will rapidly becomes writers during such an event.
