Jonathan Ellis commented on CASSANDRA-6572: ------------------------------------------- bq. We also might want to create a downgradesstables tool, to make trying out new versions even easier (by making reverting back easier). I'm even more excited about using this to get us realistic workloads to benchmark, than I am about helping people upgrade with confidence. So, downgradesstables is a nice idea but I don't think it obsoletes this. bq. If we are using this to replicate workloads for replaying a workload, then the new stress tool can be better configured to do that. Okay, so maybe we shift our goals a bit. Assuming we can tune newstress to do 50% inserts to table X, 10% reads from table Y, 40% updates to table Z, doing that by hand is a pain. What if we make this tool gather statistics like that from a live cluster, then write out a stress schema + config to emulate it? > Workload recording / playback > ----------------------------- > > Key: CASSANDRA-6572 > URL: https://issues.apache.org/jira/browse/CASSANDRA-6572 > Project: Cassandra > Issue Type: New Feature > Components: Core, Tools > Reporter: Jonathan Ellis > Assignee: Carl Yeksigian > Fix For: 2.1.1 > > Attachments: 6572-trunk.diff > > > "Write sample mode" gets us part way to testing new versions against a real > world workload, but we need an easy way to test the query side as well. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
