> NullableCoder optimized encoding via passthrough context

> Key: BEAM-469
> URL: https://issues.apache.org/jira/browse/BEAM-469
> Project: Beam
> Issue Type: Improvement
> Components: sdk-java-core
> Reporter: Luke Cwik
> Assignee: Thomas Groh
> Priority: Trivial
> Labels: backward-incompatible
> Fix For: 0.3.0-incubating
>
>
> NullableCoder should encode using the context given and not always use the
> nested context. For coders which can efficiently encode in the outer context
> such as StringUtf8Coder or ByteArrayCoder, we are forcing them to prefix
> themselves with their length.
