[zeromq-dev] SUB connected early in PUB

[Absynt Technologies]

Hi Joshua

I finally succeed in my project thank's to your help.
you can find it at :
https://github.com/KalimaSystems/LevelDbCache


It is based, mainly on clone example from zguide.
But I add persistance in levelDb, it is multi-base and for each base, multi stores.

My objective was to be able to start clients, primary server and backup in any order and to get it working.
Now it works
My error was that I was, first sending data in blocking mode.

Thanks for your help

Andre

Does the subscriber get 
data eventually? ZeroMQ's perspective is that PUB/SUB is like a radio. 
If you aren't listening when it is broadcasting, you won't get the 
messages. If you need to get previously sent messages, you need to 
overlay a pattern over top (like using separate sockets to synchronize). There are some examples in the guide and I can provide more input if 
thats the issue.

is as follows:

 question: How managed the situation in a way that will allow client to 
start before server and to be able to get the PUB SUB working
