Hi akash, for simple updates and delete scenario, you can try to do it.
During update/delete, 1) for updated/deleted segment, no need to update segmentMetadataInfo. 2) for new inserted segment, you can summary blocklet level index to segment level index, reading carbonindex/carbonindexmerge file and calculate it. ----- Best Regards David Cai -- Sent from: http://apache-carbondata-dev-mailing-list-archive.1130556.n5.nabble.com/
