[zeromq-dev] dealing with time sensitive messages in pub/sub (pub "connects")

[Robert W]

Right now the behavior of zeromq sockets is that if the sender/publisher
"connects" and the receiver/subscriber "binds" and the receiver temporarily
dies, the sender keeps the message in its queue and keeps retrying the
connection.

How do I deal with the case if my message is more time sensitive? I rather
the message be dropped if the receiver isn't there.

I know I can set the HWM on the sender to 1, but that still keeps 1 old
message that will be sent when the receiver eventually comes online.

I thought about attaching time-stamps to the message, but that can get a
little messy when I have to ensure clocks are synchronized precisely, etc.

Basically, I want the queue to be dropped when it has to reconnect (or I
don't want the socket to keep trying reconnections / I want to be notified
when the connection isn't there). What should I do for this case?

Thanks
