 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.
