It does the right thing - sstables sent to other nodes maintain their min/max timestamps so they’ll go to the right buckets The bucket is selected using the timestamp of the newest cell in the sstable If you run a major compaction, you would undo the same bucketing Cleanup works by compacting

TWCS decommission and cleanups

2017-11-15 Thread Benjamin Heiskell
Hello all, How does TWCS work when decommissioning a node? Does the data distribute across the other nodes to the current time window's sstable (like read-repairs)? Or will it compact into the sstables for the prior windows? If that's how it works, how does it decide what sstable to compact with?
