----------------------------------------------

             Summary: Allow to run full repairs in 3.0 without additional cost of anti-compaction
                 Key: CASSANDRA-13885
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-13885
             Project: Cassandra
          Issue Type: Bug
            Reporter: Thomas Steinmaurer


This ticket is basically the result of the discussion in Cassandra user list: https://www.mail-archive.com/user@cassandra.apache.org/msg53562.html

I was asked to open a ticket by Paulo Motta to think about back-porting running full repairs
without the additional cost of anti-compaction.

Basically there is no way in 3.0 to run full repairs from several nodes concurrently without
troubles caused by (overlapping?) anti-compactions. Coming from 2.1 this is a major change
from an operational POV, basically breaking any e.g. cron job based solution kicking off -pr
based repairs on several nodes concurrently.
