Rong Rong updated FLINK-9294:
-----------------------------
    Description: 
Most of the UDF function signatures that includes composite types such as 
{code}MAP{/code} {{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.

  was:
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.


> Improve type inference for UDFs with composite parameter or result type
