-------------------------------------
Summary: Execute cross region index maintenance calls outside of
row lock for transactional tables
Key: PHOENIX-3791
URL: https://issues.apache.org/jira/browse/PHOENIX-3791
Project: Phoenix
Issue Type: Bug
Reporter: James Taylor
A corner case related to PHOENIX-3789. Non transactional, mutable secondary
index maintenance relies on the the WAL edit as state so that the actual index
writes can be done later. When WAL edits are disabled, the writes to the index
table are done in the preBatchMutation while the row locks are still held which
should be avoided.
This can be fixed by either leveraging a way of passing state between
coprocessor hooks (which I'm not sure exists) or through thread locals as a
last resort.
