Since the protocol is a simple line based, its possible to manually connect to the server using a tool like netcat. A few things should be noted when manually using the protocol: - * When subscribing to a stream using ``REPLICATE``, the special token ``NOW`` can - be used to get all future updates. The special stream name ``ALL`` can be used - with ``NOW`` to subscribe to all available streams. - * The federation stream is only available if federation sending has been - disabled on the main process. - * The server will only time connections out that have sent a ``PING`` command. - If a ping is sent then the connection will be closed if no further commands - are receieved within 15s. Both the client and server protocol implementations - will send an initial PING on connection and ensure at least one command every - 5s is sent (not necessarily ``PING``). - * ``RDATA`` commands *usually* include a numeric token, however if the stream - has multiple rows to replicate per token the server will send multiple - ``RDATA`` commands, with all but the last having a token of ``batch``.
