Old store created with carbondata 1.1 version does not contain the blocklet info in the index file. On that store if merge index file is created then blocklet information will not be present in the merge index file and for first time query again carbondata file footer will be read for blocklet information retrieval. Benefits: 1. Support merge index file creation on old store 2. Improve first time query performance. Note: First time query performance will be improved only if merge index file is created before running the first query -- This message was sent by Atlassian JIRA (v6.4.14#64029)
