> Components: beam-model-fn-api

> Priority: Minor
>
> Add support for using kind for well known coder types in Apache Beam for Java
> The following specific cloud object representations for the following types
> should exist:
> kind:pair (TupleCoder with two components)
> kind:stream (IterableCoder with a single component)
> kind:global_window (GlobalWindowCoder)
> kind:length_prefix (A new type of coder which always encodes the length of
> the value type as a prefix, has a single component)
> kind:windowed_value (A wrapper coder with two components (value coder and
> window coder))
> These changes are towards having a common binary representation for certain
> well known coders across multiple languages.
