-------------------------------------
Summary: 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
Reporter: Ray Mattingly
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.
