----------------------------------
Summary: Use type informations about output, key and values from
operators to set coders
Key: BEAM-5078
URL: https://issues.apache.org/jira/browse/BEAM-5078
Project: Beam
Issue Type: Sub-task
Components: dsl-euphoria
Reporter: Vaclav Plajt
Assignee: David Moravek
Operators can (optionally) carry `TypeDescriptor` of its output, key and value
types. These can be used to determine right coders for `PCollection`s during
translation to Beam API.
Another enhancements of coders resolution are desired:
* Allow API user to disable use of `KryoCoder` as fallback coder.
* Every automatically created `KryoCoder` needs to respects classes
registrations provided by user.
* Automate creation of 'PairCoder' whenever needed.
