Hi, Based on the final points considered, I have included the following 3 points details of implementation and test cases in the document attached to JIRA. https://issues.apache.org/jira/browse/CARBONDATA-4037 PR: https://github.com/apache/carbondata/pull/3988
1. make merge index by default enable and fail the compaction, load if the merge index operation fails. 3. update table status file and the segment file only if the merge index operation succeeds. 6. Alter compact command for merge index will not do anything for new tables. It will merge for old tables only and do not delete the old index files immediately Inputs and suggestions for any changes are most welcomed. -- Sent from: http://apache-carbondata-dev-mailing-list-archive.1130556.n5.nabble.com/
