Re: Time series data with only inserts

Your compaction strategy gets triggered whenever you flush memtables to disk. Most compaction strategies, especially those designed for write-only time-series workloads, check for fully expired sstables (getFullyExpiredSStables()) “often” (DTCS does it every 10 minutes, because it’s fairly exp
