-------------------------------------
Summary: Add URNs to known transforms instead of using instanceof
checks
Key: BEAM-1192
URL: https://issues.apache.org/jira/browse/BEAM-1192
Project: Beam
Issue Type: Improvement
Components: beam-model-runner-api
Reporter: Kenneth Knowles
In the [Beam Runner AP|https://s.apache.org/beam-runner-api], transforms of
interest to runners are to be identified by URN.
Currently, Java-based runners use `instanceof` checks to both override
transforms and to implement primitive transforms. This language and
SDK-specific behavior should be replaced by adding these URNs, and checking
them.
