Subject [jira] [Commented] (CASSANDRA-12701) Repair history tables should have TTL and TWCS
Date Mon, 10 Oct 2016 00:54:20 GMT


Nate McCall commented on CASSANDRA-12701:

[~jjirsa] +1 Patch looks fine. Your linked tests have failures, but have nothing to do with
these system tables and are on several recent builds. (Thanks, [~bradfordcp]!)

> Some tools schedule a lot of small subrange repairs which can lead to a lot of repairs
constantly being run. These partitions can grow pretty big in theory. I dont think much reads
from them which might help but its still kinda wasted disk space. I think a month TTL (longer
than gc grace) and maybe a 1 day twcs window makes sense to me.
