----------------------------------
Resolution: Fixed
> Do not pull predicates out of join condition
> --------------------------------------------
>
> Key: ASTERIXDB-3573
> URL: https://issues.apache.org/jira/browse/ASTERIXDB-3573
> Project: Apache AsterixDB
> Issue Type: Bug
> Components: COMP - Compiler
> Reporter: Ali Alsuliman
> Assignee: Ali Alsuliman
> Priority: Major
>
> Avoid pulling predicates out of the (inner) join condition into a separate
> select operator.
> https://issues.apache.org/jira/browse/ASTERIXDB-3572 takes care of
> non-equality predicates and employs a hash-join as long as there is at least
> one equality predicate. With that being done, there is now no need to pull
> non-equality predicates out of the (inner) join condition. These predicates
> can still be present in the join condition together with the other equality
> predicates. This can reduce the cardinality of the join operator and improve
> performance.
