Subject Re: estimated number of keys vs ttl
Date Wed, 23 May 2018 20:03:53 GMT
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).
