--------------------------------------
Summary: When maxLookback is not enabled, IndexTool should not do
deep verification
Key: PHOENIX-6058
URL: https://issues.apache.org/jira/browse/PHOENIX-6058
Project: Phoenix
Issue Type: Bug
Reporter: Kadir OZDEMIR
Assignee: Kadir OZDEMIR
IndexTool does two types of verification, verifying the latest row versions,
and verifying all row versions within the maxLoopback windows. Verifying just
the latest version can be called shallow verification whereas verifying all
versions can be called deep verification. The maxLookback feature preserves all
row versions including delete markers within the maxLookback window. This
allows IndexTool to compare all versions of data rows with all versions of the
index rows within the window. However, due to a bug, when the maxLookback
feature is not enabled, i.e., the maxLookback window is set to zero, IndexTool
assumes the window size is infinite and thus does deep verification. Since some
versions of the index rows can be removed by compaction independently if the
maxLookback is not enabled, IndexTool may report missing or invalid index rows
by doing deep verification.
