----------------------------------
Summary: Support LEFT join in EnumerableMergeJoin
Key: CALCITE-4113
URL: https://issues.apache.org/jira/browse/CALCITE-4113
Project: Calcite
Issue Type: New Feature
Components: core
Reporter: Ruben Q L
Currently, EnumerableMergeJoin supports INNER, SEMI, and ANTI join.
The goal of this ticket is to support also LEFT join (which should be a
combination of INNER join results + ANTI join results with a NULL on the right).
LEFT EnumerableMergeJoin should maintain the order of the left-hand-side of the
join.
