Marcus Eriksson updated CASSANDRA-9143: --------------------------------------- Assignee: (was: Marcus Eriksson) > Improving consistency of repairAt field across replicas > -------------------------------------------------------- > > Key: CASSANDRA-9143 > URL: https://issues.apache.org/jira/browse/CASSANDRA-9143 > Project: Cassandra > Issue Type: Improvement > Components: Core > Reporter: sankalp kohli > Priority: Minor > > We currently send an anticompaction request to all replicas. During this, a > node will split stables and mark the appropriate ones repaired. > The problem is that this could fail on some replicas due to many reasons > leading to problems in the next repair. > This is what I am suggesting to improve it. > 1) Send anticompaction request to all replicas. This can be done at session > level. > 2) During anticompaction, stables are split but not marked repaired. > 3) When we get positive ack from all replicas, coordinator will send another > message called markRepaired. > 4) On getting this message, replicas will mark the appropriate stables as > repaired. > This will reduce the window of failure. We can also think of "hinting" > markRepaired message if required. > Also the stables which are streaming can be marked as repaired like it is > done now. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
