Sorry wasn't clear, modified my comments. Any is backed by FastPrimitiveCoder: ``` >>> from apache_beam.coders import typecoders >>> typecoders.registry.get_coder(object) FastPrimitivesCoder ``` https://github.com/apache/beam/blob/01b09725ec3066fcbb871bd16e54e5b5e0496865/sdks/python/apache_beam/coders/row_coder.py#L178 which fallbacks to PickleCoder if it isn't a primitive (or supported collections like set/list/map): https://github.com/apache/beam/blob/01b09725ec3066fcbb871bd16e54e5b5e0496865/sdks/python/apache_beam/coders/coder_impl.py#L484 I was noting by annotate your dataclass with `register_row`, it then uses RowCoder, then it's individual Any field uses FastPrimitiveCoder, instead of the whole dataclass using FastPrimitiveCoder and falling back to PickleCoder -- This is an automated message from the Apache Git Service.
