[~grandfisher], can you add to the description an example of schema, SQL query,
and relevant plans to illustrate the problem more clearly?
In the past I have worked on a similar issue, the root cause wasn't in the
_JoinPushTransitivePredicatesRule,_ but __ in a rule equivalent to
[_JoinDeriveIsNotNullFilterRule_|https://github.com/apache/calcite/blob/main/core/src/main/java/org/apache/calcite/rel/rules/JoinDeriveIsNotNullFilterRule.java]
which was creating the filter although an equivalent one was already there.
