Description

Dataflow isn't natively translating from the Beam Pipeline Proto yet, but requires SDKs to translate the graph into it's own format. Adding this hint for custom coders (Coders not known to Dataflow/Beam) avoids having dataflow re-synthesize coders from it's format, back to the pipeline proto.

Currently there's the awkward restriction on which coders should receive the ID, rather than having the SDK apply the field to all of them, but this is a good first step to get there. This restriction may be lifted on a subsequent dataflow release.
