             Summary: Create filterExecuter for each segment instead of blocklet, To improve prune performance
                 Key: CARBONDATA-3722
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-3722

          Issue Type: Improvement
            Reporter: Xingjun Hao


In the prunning, It will create filterexecuter for each blocklet, which involves a huge performance degrade when there are serveral million blocklet. 

We shall create filterexecuter per segment instead of that per blocklet.
