----------------------------------------
Summary: Query performance slows down as the number of columns
increases in like query with OR expression
Key: CARBONDATA-2252
URL: https://issues.apache.org/jira/browse/CARBONDATA-2252
Project: CarbonData
Issue Type: Bug
Reporter: Manish Gupta
Assignee: Manish Gupta
Problem: In case of OR condition with like query contains and ends with, the
filter is getting pushed down to carbon layer because of which the query is
slow as compared to spark applying the same filter on the results returned from
carbon
This is because in case of like query the execution is done by
RowLevelFilterExecutorImpl which will compute the data row by row. As the
number of columns will increase the computation time will increase thereby
increasing the query time.
