The thing with changing response types (and parameters) is that it is an API breaking change. Not directly for `RESTCatalogAdapter.handleRequest()` but for the calling `RESTCatalogAdapter.execute()` that invokes this, because it is an override of `HTTPRequest.execute()`. So with the current design of the reference IRC, I think we can either follow the exception driven approach, or implement some (not that foolproof) checks in `RESTCatalogServlet` like "if the responseBody is null and the load table endpoint was called, then return 304". The exception-driven approach seems to be the cleanest on the reference IRC side. cc @amogh-jahagirdar @nastra -- This is an automated message from the Apache Git Service.
