Jacky Li commented on CARBONDATA-3605:
--------------------------------------

This was discussed in CarbonData's dev maillist, please refer to http://apache-carbondata-dev-mailing-list-archive.1130556.n5.nabble.com/Propose-feature-change-in-CarbonData-2-0-td87540.html

In short, the performance improvement using global dictionary is not significant, but it slow down data loading speed and code maintenance is very complex.
