Re: TTL of paxos table


It's just that compaction hasn't occured. TTL works even though GCGS is 0.
There's been multiple discussions around this in the past, but we haven't
come to a consensus yet though. Some proposals to change compaction
strategy, some want to make it customisable. Treating paxos as sub-tables
has also come up and the improvements listed in CASSANDRA-13548.
TBH we should probably do 13548 and see where that gets us.
