Jeff Jirsa commented on CASSANDRA-9130:
---------------------------------------
I know this sounds obvious, but I'm repeating it for the record, because it's
relevant:
You will still introduce fragmentation during bootstrap, bulk load, and decom,
potentially thousands or tens of thousands of sstables per node for decom.
Lowing max_sstable_age_days below the table TTL is not necessarily safe, with
or without CASSANDRA-9056
> reduct default dtcs max_sstable_age

> URL: https://issues.apache.org/jira/browse/CASSANDRA-9130
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Jonathan Ellis
> Assignee: Marcus Eriksson
> Priority: Minor
> Fix For: 3.x, 2.1.x, 2.0.x

> Now that CASSANDRA-9056 is fixed it should be safe to reduce the default age
> and increase performance correspondingly. [~jshook] suggests that two weeks
> may be appropriate, or we could make it dynamic based on gcgs (since that's
> the window past which we should expect repair to not introduce fragmentation
> anymore).
