[jira] [Created] (FLINK-33547) Primitive SQL array type after upgrading to Flink 1.18.0

Xingcan Cui created FLINK-33547:
-----------------------------------

             Summary: Primitive SQL array type after upgrading to Flink 1.18.0
                 Key: FLINK-33547
                 URL: https://issues.apache.org/jira/browse/FLINK-33547
             Project: Flink
          Issue Type: Technical Debt
          Components: Table SQL / Runtime
    Affects Versions: 1.18.0
            Reporter: Xingcan Cui


We have some Flink SQL UDFs that use object array (Object[]) arguments and take boxed arrays (e.g., Float[]) as parameters. After upgrading to Flink 1.18.0, the data created by ARRAY[] SQL function became primitive arrays (e.g., float[]) and it caused argument mismatch issues. I'm not sure if it's expected.
