In many cases, they are not equivalent, unless the top level join is a
semi-join, e.g.
(T1⋈T2)⋉(T2⟖T3) on T1.a=T3.a
can be optimized to
(T1⋈T2)⋉T3 on T1.a=T3.a
It is better to give a concrete example, so that we can discuss case by case.

They are known issues. Calcite isn't doing well on join reordering, there are

I am running a TPC-H benchmark on a database system that uses Calcite as
