---------------------------------------
Summary: IndexTool to not write already correct index rows/CFs
Key: PHOENIX-5674
URL: https://issues.apache.org/jira/browse/PHOENIX-5674
Project: Phoenix
Issue Type: Improvement
Affects Versions: 4.14.3, 4.15.1
Reporter: Priyank Porwal
Fix For: 4.15.1, 4.14.4
IndexTool can avoid writing index rows if they are already consistent with
data-table. This will specially be useful when rebuilding index on DR-site
where indexes are replicated already, but rebuild might be needed for catchup.
Likewise, during upgrades from old indexing scheme to new consistent indexing
scheme, if the index data columns are consistent already, IndexTool should only
rewrite the EmptyColumn to mark the row as verified instead of writing the data
columns too.
