-----------------------------------

             Summary: JoinConditionPushRule cannot infer 'LHS.C1 = LHS.C2' from 'LHS.C1 = RHS.C1 AND LHS.C2 = RHS.C1'
                 Key: CALCITE-5073
                 URL: https://issues.apache.org/jira/browse/CALCITE-5073
             Project: Calcite
          Issue Type: Improvement
          Components: core
    Affects Versions: 1.30.0
            Reporter: Benchao Li
            Assignee: Benchao Li
             Fix For: 1.31.0


For the below SQL:
{code:java}
SELECT * FROM T1, T2, T3
WHERE T1.id = T3.id AND T2.id = T3.id{code}
Currently, JoinConditionPushRule cannot infer the condition 'T1.id = T2.id' for the first join relation.
