------------------------------------

             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.

This affects older versions as well, with 1.14.2 being the latest version that exhibits this issue.
