[jira] [Updated] (FLINK-9294) Improve type inference for UDFs with
composite parameter or result type
[ https://issues.apache.org/jira/browse/FLINK-9294?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Rong Rong updated FLINK-9294:
-----------------------------
Description:
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.
