[zeromq-dev] Is UDP transport needed in ZeroMQ?

[Daniel Krikun]

That's pretty good explanation!
Few points though:
- both plain tcp and udp are free
- both plain tcp and udp are available for any language (here they
certainly win)
- background io is great, however it is not straightforward to understand
why then there is ZMQ_NOBLOCK option in send method
- patterns are great too, especially for tcp, but they too can be hard to
understand for newcomers, for example, it is a common problem that when
using REQ/REP an application crashes due to uncaught exception, because
somebody called recv() with ZMQ_NOBLOCK and the message has not been
actually received. Also, I have found it is hard to explain the difference
between bind() vs connect() and patterns.
I'm not saying the patterns suck, they surely do not, personally I think
they are very helpful, but they are not perfect. Maybe plain udp can be
easier to grasp.
