Assignee: Xu Mingmin
> [SQL] Support Joda types for UDF arguments
> ------------------------------------------
>
> Key: BEAM-5921
> URL: https://issues.apache.org/jira/browse/BEAM-5921
> Project: Beam
> Issue Type: Bug
> Components: dsl-sql
> Reporter: Anton Kedin
> Assignee: Xu Mingmin
> Priority: Major
>
> We call ScalarFunctionImpl.create() to register a UDF with Calcite schema in
> BeamSqlEnv. Internally it uses Calcite's internal mapping
> (JavaToSqlTypeConversionRules) to map Java types to SQL types to create a
> function signature that gets registered in the schema. Problem is that this
> logic is not extensible and doesn't include Joda types support (maybe others
> as well).
> We can work around this by constructing our own subclass of Function that
> gets registered in the schema instead of calling ScalarFunctionImpl.create().
> This logic can use our own custom mapping (or fall back to Calcite
> implementation if needed).
