-------------------------------------
Summary: Remove Coder.Context from the public API
Key: BEAM-2166
URL: https://issues.apache.org/jira/browse/BEAM-2166
Project: Beam
Issue Type: Improvement
Components: sdk-java-core, sdk-py
Affects Versions: First stable release
Reporter: Robert Bradshaw
Assignee: Davor Bonaci
Justification:
* Contexts add confusion and complexity to the public API (e.g.
https://issues.apache.org/jira/browse/BEAM-1448)
* Leaf (user-written) coders are nearly always nested.
* Coders are being removed from sources, which was the initial need for context.
* It is unclear how much value, if any, this provides for internal performance.
* There may be performance (as well as simplification) gains in removing this
for the Fn API.
Fully removing this distinction from the internals can be defered until the
last bullet points are more completely investigated.
