Description

JsonToRow transform allows JSON String-\>Row conversion but requires users to know and specify the correct schema upfront. It would be great to be able to infer the schema from a message sample.

Imported from Jira [BEAM-4198](https://issues.apache.org/jira/browse/BEAM-4198). Original Jira may contain additional context.
