-----------------------------------------
Summary: Improve RelMdPredicates performance
Key: CALCITE-2401
URL: https://issues.apache.org/jira/browse/CALCITE-2401
Project: Calcite
Issue Type: Bug
Reporter: Zoltan Haindrich
In CALCITE-2384 a simplify feature was disabled - to prevent performance
degradation of RelMdPredicates
I think that the algorithm which tries out all the combination of the variables
could be probably improved to while it's doing the same - it doesn't run
RexSimplify that many times.
