             Summary: Add support for generating optimized logical plan for simple query(project, filter, values and union all)
                 Key: FLINK-11966
                 URL: https://issues.apache.org/jira/browse/FLINK-11966
             Project: Flink
          Issue Type: New Feature
          Components: API / Table SQL
            Reporter: godfrey he
            Assignee: godfrey he


Add support for generating optimized logical plan for simple query,
1. project and filter: SELECT a, b + 1 FROM MyTable WHERE b > 2
2. values: SELECT * FROM (VALUES (1, 2, 3)) AS T(a, b, c)
3. union all: SELECT a, c FROM (SELECT a, c FROM MyTable1 UNION ALL SELECT a, c FROM MyTable2)

{{Union}} depends on {{Aggregate}} to eliminate duplicates, so it will be introduced after {{Aggregate}} spported.
