Wail Y. Alkowaileet resolved ASTERIXDB-3113.
--------------------------------------------
Resolution: Fixed
> Allow the use hash-join with redundant variables
> ------------------------------------------------
>
> Key: ASTERIXDB-3113
> URL: https://issues.apache.org/jira/browse/ASTERIXDB-3113
> Project: Apache AsterixDB
> Issue Type: Bug
> Components: COMP - Compiler
> Reporter: Wail Y. Alkowaileet
> Assignee: Wail Y. Alkowaileet
> Priority: Major
>
> The following join currently uses broadcast join instead of hash-joinÂ
> {code:java}
> SELECT COUNT(*)
> FROM Orders o, LineItem l
> WHERE o.o_orderkey = l.l_orderkey
> AND o.o_orderkey = l.l_suppkey{code}
> As a result of having one attribute on one side and two attributes on the
> other side. The broadcast join would be much slower in most cases. Hence,
> this should be rectified.
