Zeromq XPUB/XSUB proxy only for subscription messages? -
i want prevent subscribers subscribing topics in zeromq. idea use xpub/xsub proxy , drop subscriptions topics in proxy. however, concern messages go through proxy in case, not subscription messages. wouldn't performance issue? possible have subscription messages go through proxy , regular messages directly between pub/sub sockets?
it possible create talk zmq
, beyond scope of xsub/xpub
. it's beyond scope of pub/sub
.
by using router
, dealer
can build protocol doing behavior, , in extreme cases usable, maybe necessary.
but, guess isn't problem yet. if not sending huge amounts of data, perform great you. add multiple xsub/xpub
servers , distribute load having each subscriber connect different servers (load balancing). again, start engineering such setups when needed.
