## Proposed changes eliminate redundant join when find hashing join condition such as for plan: ``` T1 join T2 on T1.id = T2.id join T3 on T1.id = T3.id and T2.id = T3.id ``` we infer a new predicate T1.id = T2.id which is redundant. Therefore we need to eliminate it when find hash condition ## Further comments If this is a relatively large or complex change, kick off the discussion at [[email protected]](mailto:[email protected]) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
