Subject Re: Dynamically adding avro schema to AvroSchemaRegistry at runtime
Date Mon, 23 Oct 2017 14:35:49 GMT

Using an external schema registry is the way to go. The embedded one is
meant for ease of use, but once you grow beyond an initial phase, the best
practice is to have a full service and potentially use standard InvomeHTTP
to perform operations beyond just lookups.

Does it help?
