Custom Payload

Native protocol version 4+ allows for a custom payload to be sent between clients and custom query handlers. The payload is specified as a string:binary_type dict holding custom key/value pairs.

By default these are ignored by the server. They can be useful for servers implementing a custom QueryHandler.
