Hi Ajantha, Thanks for your points.
Now actually we cache the splits, actual join will be faster and, even though the pruning doesn't happen it wont affect the performance much. This is learned from the test we did during POC and it doesn't make much difference in performance, basically no degrade as such. And having said that, in actual use cases or I can say customer scenario, when you have huge target table in data warehouse or data lake for analytics, the CDC will be on small portion of data itself. Changing the whole table is rarest scenario, so it should be fine. Thanks Regards, Akash R -- Sent from: http://apache-carbondata-dev-mailing-list-archive.1130556.n5.nabble.com/
