---------------------------------------------
Summary: Introduce Latency Target for Stress
Key: CASSANDRA-8686
URL: https://issues.apache.org/jira/browse/CASSANDRA-8686
Project: Cassandra
Issue Type: Improvement
Reporter: jonathan lacefield
Priority: Minor
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.
For example:
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.
