             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.
