Description:
The default compaction strategy for {{system.paxos}} table is LCS for
performance reason: CASSANDRA-7753. But for CAS heavily used cluster, the
system is busy with {{system.paxos}} compaction.
As the data in {{paxos}} table are TTL'ed, TWCS might be a better fit. In our
test, it significantly reduced the number of compaction without impacting the
latency too much:
!test11.png!
The time window for TWCS is set to 2 minutes for the test.
Here is the p99 latency impact:
!test2.png!
the yellow one is LCS, the purple one is TWCS. Average p99 has about 10%
increase.
