This item is a request to add a latency target to the rate option for the new stress tool. The goal of the latency target would be to provide a guideline for SLAs to the stress tool so the stress tool can determine threads and throughputs that can be sustained while meeting the SLA targets.
cassandra-stress [options/commands] -rate latency p90=5 p95=10 p99=100
The outcome of this command would be a stress execution that would gradually increase threads, and hence throughput (trans/sec), until the latency profile can no longer be satisfied with the current workload (yaml file definition) and/or cluster. This would provide a ceiling for throughput and connections for the given cluster, workload, and SLA profile.
