Hey everyone, I've written a doc for a new Enrichment Transform in Beam. I will note that this transform will be built on top of RequestResponseIO <https://github.com/apache/beam/blob/master/sdks/java/io/rrio/src/main/java/org/apache/beam/io/requestresponse/RequestResponseIO.java> (Implementation is in progress for Java SDK <https://github.com/apache/beam/pulls?q=is%3Apr+%5Brrio%5D> and Python SDK <https://github.com/apache/beam/pull/29303>). I wanted to share this early to get the discussion started on the user-facing API at least.
