> URL: https://issues.apache.org/jira/browse/SAMZA-1958
> Project: Samza
> Issue Type: Sub-task
> Components: sql
> Reporter: Weiqing Yang
> Priority: Major
> Fix For: 0.15.0
>
>
> Currently if users implement new UDFs or if Samza SQL implements a new system
> UDF, they need to manually register that UDF's information in the
> "listFunctions" of Samza executor. So we may need to require UDFs to provide
> a function of getting their "SamzaSqlUdfDisplayInfo", then Samza executor can
> get the UDF information from SamzaSqlApplicationConfig.udfResolver(or
> SamzaSqlApplicationConfig.udfMetadata) instead of registering UDFs manually.
