Re: estimated number of keys vs ttl

I believe that key estimates won't immediately respond to expired TTL, Not until after compaction has completely dropped the records (which will include subtle logic related to gc_grace and partitions with data in multiple SSTables). On Wed, May 23, 2018 at 6:18 AM Rahul Singh

Re: estimated number of keys vs ttl

If the TTL actually reduces the key count , should. It’s possible to TTL a row from a partition but not the whole partition. 1 key = 1 partition != 1 row != 1 cell -- Rahul Singh rahul.si...@anant.us Anant Corporation On May 23, 2018, 6:07 AM -0500, Grzegorz Pietrusza ,

estimated number of keys vs ttl

Hi I'm using tablestats to get estimated number of partitioning keys. In my case all writes are done with TTL of a few days. Is the key count decreased when TTL hits? Regards Grzegorz
