-------------------------------------
Summary: Prevent index from getting out of sync with data table
under high concurrency
Key: PHOENIX-4089
URL: https://issues.apache.org/jira/browse/PHOENIX-4089
Project: Phoenix
Issue Type: Bug
Reporter: James Taylor
Under high concurrency, we're still seeing the index get out of sync with the
data table. It seems that the particular case is when the same Put occurs with
the same time stamp from different clients, based on the locking we do, Phoenix
thinks a different Put was the last one than HBase does, leading to
inconsistencies.
The solution is to timestamp the cells on the server-side after the lock has
been taken. The new concurrent unit test passes 50x with this in place, while
it otherwise fails 1/10 of the time (or more on HBase 1.3).
