interesting jeff, thank you. ok so this is regarding new data merging with old data, what about old sstables that were suddenly merged on many nodes (as if i ran alter table to size tiered)? i do not have the sstables themselfs now, but it is definitly something that happened, one day we had sstables grouped by windows all working as planned, and a week later all the sstables had timestamp of last couple of days, all this happened on multiple tables configured with twcs. is there something you know that might cause such a thing? if i understand correctly once i have an sstable with a max timestamp tha is older then the defined window, it should never be part of a compaction set.
dor - thanks, when is that version planned to be released? gil On Wed, Dec 19, 2018 at 8:38 PM Jeff Jirsa <jji...@gmail.com> wrote: > Yes it can cause issues. > No there's no way to disable it in any
