Roman Churganov updated CALCITE-6983:
-------------------------------------
Description:
An issue in `SortJoinTransposeRule` same as in `SortUnionTransposeRule ` been
fixed in CALCITE-6647 , now can be reproduced with a query like
{code:sql}
SELECT t5.fn1, t8.m_fn
FROM (
SELECT id AS fn1 FROM foo WHERE sd = ?
UNION SELECT id FROM bar WHERE d = ?
UNION SELECT id FROM baz WHERE id = ? ) AS t5
LEFT JOIN (SELECT id AS m_fn FROM (
SELECT id, aoguid FROM foo2
WHERE EXISTS (SELECT 1 FROM (
SELECT buildnum AS fn2
FROM v1_dhouse) AS t7 WHERE aoguid = t7.fn2 ) ) AS t ) AS t8
ON t5.fn1 = t8.m_fn
FETCH NEXT ? ROWS ONLY
{code}
which hangs on building a plan, with a debug log can see growing plans,
eventually it fails with StackOverflow...,
