Hi, Thanks for testing the performance. We have also observed this performance difference and working on to improve the same. Please check my latest discussion (http://apache-carbondata-dev-mailing-list-archive.1130556.n5.nabble.com/CarbonData-Performance-Optimization-td62950.html) to improve scan performance and raised PR (still WIP) for the same. And also there is one more discussion (http://apache-carbondata-dev-mailing-list-archive.1130556.n5.nabble.com/Discussion-Carbondata-Store-size-optimization-td62283.html) to optimize store and improve performance.
Regards, Ravindra. -- Sent from: http://apache-carbondata-dev-mailing-list-archive.1130556.n5.nabble.com/
