Chris Lohfink updated CASSANDRA-20586:
--------------------------------------
Resolution: Fixed
Status: Resolved (was: Triage Needed)
> Consider increasing default for auto_repair.sstable_upper_threshold to a
> higher value
> -------------------------------------------------------------------------------------
>
> Key: CASSANDRA-20586
> URL: https://issues.apache.org/jira/browse/CASSANDRA-20586
> Project: Apache Cassandra
> Issue Type: Improvement
> Components: Consistency/Repair
> Reporter: Andy Tolbert
> Assignee: Jaydeepkumar Chovatia
> Priority: Normal
>
> Auto repair's {{sstable_upper_threshold}} default is currently defined as:
> {noformat}
> # # Threshold to skip repairing tables with too many SSTables. Defaults
> to 10,000 SSTables to avoid penalizing good
> # # tables.
> # sstable_upper_threshold: 10000
> {noformat}
> For clusters with denser nodes (multi-TB) and with LCS, 10k+ SSTables for a
> given table is not unusual. It's probably best to have a higher threshold so
> repairs don't completely stop working for a table, so maybe we should perhaps
> set this to a default value that is higher and operators can decrease it
> selectively?
> A default between 30000-50000 would probably be more sensible.
