-----------------------------------------
Summary: Enable CompactionScanner for flushes
Key: PHOENIX-7593
URL: https://issues.apache.org/jira/browse/PHOENIX-7593
Project: Phoenix
Issue Type: Improvement
Affects Versions: 5.2.1, 5.2.2, 5.3
Reporter: Sanjeet Malhotra
Assignee: Sanjeet Malhotra
PHOENIX-7402 removed the preFlush hook because we couldn't query syscat to get
the PTable object in the context of flush. This was needed to get table level
max lookback stored in SYSCAT and emptyCF/emptyCQ. PHOENIX-7587 has reverted
table level max lookback change as now we have an alternative but to introduce
preFlush hook back we need a way to determine emptyCF/emptyCQ in
CompactionScanner w/o retrieving PTable from syscat.
preFlush hook is important to avoid writing multiple versions of the same row
to the storefile.
