>                 URL: https://issues.apache.org/jira/browse/FLINK-7272
>             Project: Flink
>          Issue Type: New Feature
>          Components: Table API & SQL
>    Affects Versions: 1.3.1

> 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.
