> Support SQL IN with more than 20 elements in streaming
> ------------------------------------------------------
>
> Key: FLINK-7272
> URL: https://issues.apache.org/jira/browse/FLINK-7272
> Project: Flink
> Issue Type: New Feature
> Components: Table SQL / API
> Affects Versions: 1.3.1
> Reporter: Timo Walther
> Priority: Major
> Labels: stale-major
>
> 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.
> This problem also occurs when null is contained in the testing set. So this
> should get higher priority.
