Thanks for the feedback. I will look at lbbroker examples.
In case I can't use the router broker socket approach in my use case, what do
you think about creating multiple DEALER sockets on client side - one for each
server endpoint (ROUTER socket)? Is it recommended by zeromq best practices?
In my use case, client has list of server endpoints and client selects server
before sending the message.
Thanks
Ashish

Subject: Re: [zeromq-dev] zeromq DEALER client to multiple servers (ROUTER)
If you connect a DEALER to multiple endpoints it will distribute messages to
all of its connections. I think this is a round robin distribution.
If you have some specific logic where you need to choose which server to talk
to, you would need a router socket so that you can specify the address. You
could implement this as a separate routing so that your DEALER connects to one
ROUTER on a broker and then the broker decides which server to talk to. See the
lbbroker examples, such as:
https://github.com/imatix/zguide/blob/master/examples/C/lbbroker2.c
Cheers,
Matt

always goes to the first connected endpoint. followed following steps: -
create DEALER socket - connect to first endpoint - then on the run time, add
another endpoint to the socket by using
socket.connect(endpoint). Do I need to reconnect?
