> How does a new client can still work with old server? Good question. The trick here is that we don't do any protobuf modifications. We serialize the protobuf content to a new Java object structure which makes it possible to handle additional parameters (for example: EC can handle more properties instead of just the one `replicationFactor`).  This patch modifies the SCM to use `replicationConfig` everywhere, but the logic is the same as before. With this approach on the EC branch we can add a new replicationConfig implementation and all the pipeline managers will serve it. -- This is an automated message from the Apache Git Service.
