------------------------------------------
Summary: Create automated performance workloads and metrics
collection for improving compaction performance
Key: CASSANDRA-10384
URL: https://issues.apache.org/jira/browse/CASSANDRA-10384
Project: Cassandra
Issue Type: Task
Components: Core
Reporter: Ariel Weisberg
This is a high level ticket (Epic or Story) and needs to be decomposed into
smaller tasks.
Improving compaction performance is currently a priority. To reduce the risk of
choosing what path to take and to allow us to prune paths that don't end up
being productive we need to automate measuring the performance of compaction,
maintaining a historical log, and collecting detailed metrics that explain why
we are seeing what we are seeing.
This relates to some of the work for CASSANDRA-9259 where sub-tthe asks are
closely related. Bulk reading appears to be 60% of the CPU time associated with
compaction according to flight recorder. There is also almost complete overlap
in the interest in automating the collection of metrics that can be use to
explain and advocate for pursuing (or abandoning) specific changes.
