-------------------------------------------
Summary: Expose the execution results of a cleanup command to a
virtual table
Key: CASSANDRA-19760
URL: https://issues.apache.org/jira/browse/CASSANDRA-19760
Project: Cassandra
Issue Type: Improvement
Components: Observability/Metrics
Reporter: Maxim Muzafarov
Assignee: Maxim Muzafarov
When a cleanup command is called, the compaction process is triggered under the
hood is triggered accordingly. However, if there is nothing to compact or the
cleanup command returns with a status other than SUCCESSFUL, there is no way to
get the execution results of the command that was run. This is especially true
when using any kind of automation/scripting on top of JMX or as a nodetool
wrapper.
We want to see some information about the cleanup command (id, status, etc.)
that was executed. As a possible solution, we can use a small heap buffer with
the history of the executed commands to expose the buffer in a virtual table
accordingly.
Operations with other OperationType e.g. SCRUB, VERIFY etc. can be exposed in
the same way.
