Rong Rong created FLINK-9294: -------------------------------- Summary: Improve type inference for UDFs with composite parameter or result type Key: FLINK-9294 URL: https://issues.apache.org/jira/browse/FLINK-9294 Project: Flink Issue Type: Improvement Components: Table API & SQL Reporter: Rong Rong
For now most of the UDF function signatures that includes composite types such as `MAP` `ARRAY`, etc would require user to override `getParameterType` or `getResultType` method explicitly. It should be able to resolve the composite type based on the function signature. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
