[jira] [Created] (FLINK-7272) Support SQL IN with more 20 elements
in streaming
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.
