[jira] [Commented] (BEAM-1930) Abstract Coder translation from Runner API Protos

    [ https://issues.apache.org/jira/browse/BEAM-1930?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15964647#comment-15964647 ] 

Luke Cwik commented on BEAM-1930:
---------------------------------

I think with Jackson/ObjectMapper you could do the same thing and have it convert from proto -> json -> Java coder and then we might be able to drop CloudObject usage within Coder.

> Instead of having a large switch statement that constructs known coders, have a map from URN to an interface that takes {{(RunnerApi.Coder, RunnerApi.Components)}} and produces a java Coder, and delegate all calls in {{fromProto}} to that map.
