< p > The pub/sub system does not guarantee order between what you manually send using WebSocket.send
and what you publish using WebSocket.publish. WebSocket messages are perfectly atomic, but the order in which they appear can get scrambled if you mix the two sending functions on the same socket.
This shouldn' t matter in most applications. Order is guaranteed relative to other calls to WebSocket.publish.< / p >
< p > Also keep in mind that backpressure will be automatically managed with pub/sub, meaning some outgoing messages may be dropped if backpressure is greater than specified maxBackpressure.< / p >
