----------------------------------
Summary: EnumerableJoinRule: remove unnecessary Filter on top of
INNER Join
Key: CALCITE-3535
URL: https://issues.apache.org/jira/browse/CALCITE-3535
Project: Calcite
Issue Type: Task
Components: core
Affects Versions: 1.21.0
Reporter: Ruben Q L
Assignee: Ruben Q L
Fix For: 1.22.0
With the implementation of CALCITE-2973, now EnumerableHashJoin supports all
type of conditions (not just equi joins). However, there is still one TODO in
EnumerableHashJoinRule that, in case of an INNER Join, creates a Filter with
the non-equi conditions on top of the EnumerableHashJoin, this filter is not
really needed, since now EnumerableHashJoinRule can support the full
conditions, including the non-equi items.
