Rui Wang updated BEAM-9969:
---------------------------
Description:
There are four types of implementation of table-valued function:
1. FixedSchemaOutput. The output of the TVF is pre-defined.
2. InputSchemaForwardToOutput. The output schema of the TVF is the same as
input schema.
3. InputSchemaForwardToOutputWithAppendedColumns. The output schema of the TVF
is the same as input schema plus columns appended.
4. TemplatedTVF. Parameters of TVF are templated. (e.g. ANY TYPE, ANY TABLE,
etc.)
