---------------------------------------
Summary: IndexTool can just update empty_column with verified if
rest of index row matches
Key: PHOENIX-5682
URL: https://issues.apache.org/jira/browse/PHOENIX-5682
Project: Phoenix
Issue Type: Improvement
Affects Versions: 4.14.3, 4.15.1
Reporter: Priyank Porwal
Fix For: 4.15.1, 4.14.4, 4.16.0
When upgrading from old indexing design to new consistent indexing,
IndexUpgradeTool kicks off IndexTool to rebuild the index. This index rebuild
rewrites all index rows. If any index row was already consistent, it is
rewritten + empty_column is updated with verified flag.
IndexTool could potentially just update empty_column if rest of the index row
matches with data rows. This would save the massive writes to the underlying
dfs, as well as other side effects of these writes to replication.
