Roman Churganov updated CALCITE-6983:
-------------------------------------
Description:
An issue in `SortJoinTransposeRule` same as in `SortUnionTransposeRule ` has
fixed in CALCITE-6647 , can be reproduced with a query like
{code:sql}
SELECT x.c11 FROM (
SELECT tt1.c11 FROM (
SELECT c11 FROM sch1.foo as cp1 LIMIT ?
) AS tt1
UNION ALL
SELECT tt2.c11 FROM (
SELECT c11 FROM sch1.foo as cp2 LIMIT ?
) AS tt2
) AS x LIMIT ?
{code}
which hangs on building a plan, with a debug log can see growing plans,
eventually it fails with StackOverflow...,
