--------------------------------------------------------------
Very detailed debugging info, thanks for that [~rubenql] ~ Thanks for the
fixing of method Linq4j.CompositeEnumerable#enumerator.
So the old EnumerableDefaults#nestedLoopJoin still has the connection
leak/not-close problem right ?

> With the implementation of CALCITE-2973, now EnumerableHashJoin supports all
> type of conditions (not just equi joins). However, there is still one
> [TODO|https://github.com/apache/calcite/blob/07c1efbb2b42a0e27f9d01968d357d9c1e17cd51/core/src/main/java/org/apache/calcite/adapter/enumerable/EnumerableJoinRule.java#L89]
> in EnumerableHashJoinRule that, in case of an INNER Join, creates a Filter
> with the non-equi conditions on top of the EnumerableHashJoin (created only
> with the equi-conditions), this filter is not really needed, since now
> EnumerableHashJoinRule can support the full condition: equi and non-equi
> items.
