Timo Walther created FLINK-7272:
-----------------------------------

             Summary: Support SQL IN with more 20 elements in streaming
                 Key: FLINK-7272
                 URL: https://issues.apache.org/jira/browse/FLINK-7272
             Project: Flink
          Issue Type: New Feature
          Components: Table API & SQL
            Reporter: Timo Walther


During the implementation of FLINK-4565 I noticed that an "IN" operation with more than 20 elements is converted into {{LogicalValues}} + {{LogicalJoin}} operation. Since this is not possible in streaming, we should add some rule that merges both operators either into a Correlate or Calc.
