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

             Summary: [SQL] Support predicate push-down without project push-down
                 Key: BEAM-8508
                 URL: https://issues.apache.org/jira/browse/BEAM-8508
             Project: Beam
          Issue Type: Improvement
          Components: dsl-sql
            Reporter: Kirill Kozlov
            Assignee: Kirill Kozlov


In this PR: [https://github.com/apache/beam/pull/9863]

Support for Predicate push-down is added, but only for IOs that support project push-down.

In order to accomplish that some checks need to be added to not perform certain Calc and IO manipulations when only filter push-down is needed.
