-----------------------------------------
Summary: Allow different compaction strategies per-DC
Key: CASSANDRA-18103
URL: https://issues.apache.org/jira/browse/CASSANDRA-18103
Project: Cassandra
Issue Type: Improvement
Reporter: Johnny Miller
I have a requirement for deploying an additional DC. The cluster is split
between multiple DCS - on-prem and a cloud.
Several tables use LCS and perform fine on bare metal and not so well on the
infrastructure allocated for the cloud DC.
The cloud deployment is intended to run offline analytical batch-type workloads
where the criticality of read response times does not necessitate LCS. The cost
of presenting appropriate storage for LCS is high and unnecessary for the
system requirements or budget.
The JMX call to change compaction locally for testing/migrating compaction,
unfortunately, does not survive restarts, schema changes etc.
It would be very helpful to indicate on the table what compaction strategy to
use per dc or make the JMX change durable.
