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

             Summary: [SQL] FilterAggregateTransposeRule does not transform logical plan as desired.
                 Key: FLINK-3487
                 URL: https://issues.apache.org/jira/browse/FLINK-3487
             Project: Flink
          Issue Type: Bug
            Reporter: Chengxiang Li
            Priority: Minor


{noformat}
val t = CollectionDataSets.get3TupleDataSet(env).as('a, 'b, 'c)
      .groupBy('a)
      .select('a, 'b.avg as 'value)
      .filter('a === 1)
{noformat}
For this query, filter is expected to be pushed down before the aggregate by FilterAggregateTransposeRule, currently the optimzied logical plan is not what we desired.
