-----------------------------------------------------
This is something we potentially want to prioritize to better support RowCoder
for x-lang.
> Add support for remaining data types in python RowCoder

> Key: BEAM-7996
> URL: https://issues.apache.org/jira/browse/BEAM-7996
> Project: Beam
> Issue Type: New Feature
> Components: cross-language, sdk-py-core
> Reporter: Brian Hulette
> Priority: P1
> Time Spent: 9h 20m
> Remaining Estimate: 0h

> In the initial [python RowCoder
> implementation|https://github.com/apache/beam/pull/9188] we only added
> support for the data types that already had coders in the Python SDK. We
> should add support for the remaining data types that are not currently
> supported:
> * INT8 (ByteCoder in Java)
> * INT16 (BigEndianShortCoder in Java)
> * FLOAT (FloatCoder in Java) (Note: doubles are supported, this is
> specifically for single-precision)
> * --BOOLEAN (standard beam:coder:bool:v1, BooleanCoder in Java)--
> * --BYTES (standard beam:coder:bytes:v1, ByteArrayCoder in Java)--
> * --Map (MapCoder in Java)--
> We might consider making those coders standard so they can be tested
> independently from RowCoder in standard_coders.yaml. Or, if we don't do that
> we should probably add a more robust testing framework for RowCoder itself,
> because it will be challenging to test all of these types as part of the
> RowCoder tests in standard_coders.yaml.
