Joshua McKenzie updated CASSANDRA-11696:
----------------------------------------
Priority: Critical (was: Major)
> Incremental repairs can mark too many ranges as repaired
> --------------------------------------------------------
>
> Key: CASSANDRA-11696
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11696
> Project: Cassandra
> Issue Type: Bug
> Reporter: Joel Knighton
> Assignee: Paulo Motta
> Priority: Critical
>
> Incremental repairs are tracked using a parent session - a subordinate repair
> session is created for each range in the repair. When a node participating in
> the repair receives a validation request, it will reference the sstables in
> the parent repair session. When all subordinate sessions conclude, each node
> anticompacts SSTables based on the parent repair session for the whole range
> of the repair, but these referenced SSTables may have only been present for
> the validation of some subset of the ranges because the SSTables were created
> concurrent with the parent repair session.
