[jira] [Created] (CARBONDATA-3849) Push down array_contains as equal to filter for array of primitive types
Ajantha Bhat created CARBONDATA-3849: Summary: Push down array_contains as equal to filter for array of primitive types Key: CARBONDATA-3849 URL: https://issues.apache.org/jira/browse/CARBONDATA-3849 Project: CarbonData Issue Type: Improvement Reporter: Ajantha Bhat Assignee: Ajantha Bhat problem: Currently array_contains() UDF is not pushed down to carbon. So, carbon has to scan all the rows for query having this UDF. scanning all the rows reduces the query performance. solution: push down array_contains() for all the array of primitive type as equals to filter. Having as equals to filter, we can break the scanning of elements in array once found. -- This message was sent by Atlassian Jira (v8.3.4#803005)
