----------------------------------------
Status: Ready to Commit (was: Patch Available)
> Fix scheduling of speculative retry threshold recalculation
> -----------------------------------------------------------
>
> Key: CASSANDRA-14338
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14338
> Project: Cassandra
> Issue Type: Bug
> Reporter: Aleksey Yeschenko
> Assignee: Aleksey Yeschenko
> Priority: Major
> Fix For: 4.0
>
>
> Realized after committing CASSANDRA-14293 that it's slightly broken: when
> updating from a static to a dynamic speculative retry policy, the refresher
> will never be scheduled.
> Also realised that the whole thing is a bit dumb. We don't need a latency
> calculator runnable per {{ColumnFamilyStore}}, we should have one per node,
> that does in batch refresh thresholds for every table. It's one fewer thing
> to manage, and allows to get rid of {{isDynamic()}} method in
> {{SpeculativeRetryPolicy}}, which I thought was clever at the time.
