We're on 2.X so this information may not apply to your version, but you
should see:
1) A log statement upon compaction, like "Writing large partition",
including the primary partition key (see
https://issues.apache.org/jira/browse/CASSANDRA-9643). Configurable
threshold in cassandra.yaml
2) Probl
Is there any metric or way to find out if any partition has grown beyond a
certain size or certain row count?
If a partition reaches a certain size or limit, I want to stop sending
further write requests to it. Is it possible?
