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

             Summary: Push down the deterministic predicates that are after the first non-deterministic
                 Key: SPARK-22895
                 URL: https://issues.apache.org/jira/browse/SPARK-22895
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.2.1
            Reporter: Xiao Li
            Assignee: Xiao Li


Currently, we do not guarantee an order evaluation of conjuncts in either Filter or Join operator.
This is also true to the mainstream RDBMS vendors like DB2 and MS SQL Server. Thus, we should
also push down the deterministic predicates that are after the first non-deterministic, if
possible.
