Description

Coders must be understood by the SDK harness that is encoding or decoding the associated elements. However, the pipeline runner is capable of constructing partial coders, where an unknown coder is replaced with a ByteArrayCoder. It then can decompose the portions of elements it is aware of, without having to understand the custom element encodings.

 

This should go in CoderTranslation, as an alternative to the full-fidelity rehydration of a coder.
