Daniel Cheng created FLINK-25491:
------------------------------------
Summary: Code generation: init method exceeds 64 KB when there is
a large IN filter with Table API
Key: FLINK-25491
URL: https://issues.apache.org/jira/browse/FLINK-25491
Project: Flink
Issue Type: Bug
Components: Table SQL / API
Affects Versions: 1.14.2
Reporter: Daniel Cheng
When using Table API, if you are filtering using an IN filter with a lot of
values, e.g. `$(colName).in(<many values>)`, it will result in the error
```
Code of method "<init>(...)V" of class "BatchExecCal$3006" grows beyond 64 KB
```
The size of the init method mainly comes from the below method, which
initializes the hash set with all the values in the filter.
[https://github.com/apache/flink/blob/master/flink-table/flink-table-planner/src/main/scala/org/apache/flink/table/planner/codegen/CodeGeneratorContext.scala#L409]
This affects older versions as well, with 1.14.2 being the latest version that
exhibits this issue.
