---------------------------------------
Summary: Inaccurate MutationState numRows and estimatedSize
counting
Key: PHOENIX-5611
URL: https://issues.apache.org/jira/browse/PHOENIX-5611
Project: Phoenix
Issue Type: Bug
Affects Versions: 4.14.2
Reporter: Alex Batyrshin
Attachments: numRows.patch
Hello,
I found that numRows decreased by HBase mutations count instead of SQL rows
count. In case of NULL in UPSERT there will be 1 SQL row == 2 HBase mutation.
UPSERT INTO test VALUES ('foo', NULL) => HBase Put Mutation + HBase Delete
Mutation
Also I found that estimatedSize could be calculated via
KeyValueUtil.getEstimatedRowMutationSize and via
RowMutationState.calculateEstimatedSize. Last one doesn't take into account
length of row keys, so result KeyValueUtil.getEstimatedRowMutationSize !=
RowMutationState.calculateEstimatedSize
