----------------------------------------
Summary: 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
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.
