-------------------------------------
Assignee: Ray Mattingly
> Region reopen procedure should support some sort of throttling
> --------------------------------------------------------------
>
> Key: HBASE-28215
> URL: https://issues.apache.org/jira/browse/HBASE-28215
> Project: HBase
> Issue Type: Improvement
> Components: master, proc-v2
> Reporter: Ray Mattingly
> Assignee: Ray Mattingly
> Priority: Major
>
> The mass reopening of regions caused by a table descriptor modification can
> be quite disruptive. For latency/error sensitive workloads, like our user
> facing traffic, we need to be very careful about when we modify table
> descriptors, and it can be virtually impossible to do it painlessly for busy
> tables.
> It would be nice if we supported configurable batching/throttling of
> reopenings so that the amplitude of any disruption can be kept relatively
> small.
