[jira] [Commented] (CASSANDRA-11491) Split repair job into tasks per table

["Paulo Motta (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-11491?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15276539#comment-15276539 ] 

Paulo Motta commented on CASSANDRA-11491:
-----------------------------------------

Increasing priority of this since this will allow running anti-compactions after each table is finished, and release sstable references earlier to avoid OOMing when running incremental repair in multiple tables (or keyspace-level).

> We currently split a parent repair session into multiple repair sessions, one per range. Each repair session is further split into multiple repair jobs, one per table.
> As we move into an auto-repair world with CASSANDRA-11190, with repair settings per table, it will probably simplify things if we reason about repair sessions on a per-table basis.
> Besides simplifying current code, this will simplify adding more advanced scheduling of repair tasks per table and other optimizations.
