-------------------------------------
Summary: Server-side delete / upsert-select potentially blocked
after a split
Key: PHOENIX-5005
URL: https://issues.apache.org/jira/browse/PHOENIX-5005
Project: Phoenix
Issue Type: Bug
Affects Versions: 4.14.1
Reporter: Vincent Poon
After PHOENIX-4214, we stop inbound writes after a split is requested, to avoid
split starvation.
However, it seems there can be edge cases, depending on the split policy, where
a split is not retried. For example, IncreasingToUpperBoundSplitPolicy relies
on the count of regions, and balancer movement of regions at t1 could make it
such that the SplitPolicy triggers at t0 but not t2.
However, after the first split request, in UngroupedAggregateRegionObserver the
flag to block inbound writes is flipped indefinitely.
