> Key: CASSANDRA-11966
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11966
> Project: Cassandra
> Issue Type: Improvement
> Components: Observability
> Reporter: Chris Lohfink
> Assignee: Chris Lohfink
> Priority: Minor
>
> Currently in traces, logs, and stacktraces you cant really associate the
> thread name with the pool since its just "SharedWorker-#". Calling setName
> around the task could improve logging and tracing a little while being a
> cheap operation.
