Replace ZeroMQ library for a pure golang ZeroMQ library about go-mod-messaging HOT 11 CLOSED

@jduranf thanks for the suggestion.
since it states [WIP] Pure-Go implementation of ZeroMQ-4, do you know whether it is ready to be used in production?

from go-mod-messaging.

If I'm not wrong, the WIP is because not all ZeroMQ features are implemented. But the main features used by EdgeX, which are PUB/SUB, are implemented:
go-zeromq/zmq4#9

Anyway, the main developer is @sbinet, and maybe we can ask him if the library is ready for production.

from go-mod-messaging.

the push/pull and pub/sub sockets are ok.
I've used them for a CERN application and they are also used in gophernotes.

but "production" is a vague term, w/o explicit working points and expected performances.
I must admit I haven't put time into properly describing the performances of go-zmq/zmq4: "it was working for me/my use cases (TM)".

Per Ireland Planning Meeting, this issue is in scope for Ireland release.
"Paper Study" shows that alternative suggestion (go-zeromq/zmq4) would be suitable replacement

EdgeX PM to make API comparison and check for viability of replacement library with current pebbe/zmp4.

from go-mod-messaging.

Not trivial switching modules as the APIs are quite different so more time will be needed to understand the go-zmq/zmq4 API and how to rewrite our ZMQ implementation using it.

Should not cause breaking changes if replaced so a target for Jakarta??

Correct, internal only

Since Edgex Foundry 2.0, Redis is the default Messaging Bus, why not move ZeroMQ support out of this library. Any services (such as core services) that need ZeroMQ support option, could import ZeroMQ adapter independently. But other services (application services, device services), could choose weather support ZeroMQ or not. Finally, we would have the option to get rid of tricky CGO stuff.

from go-mod-messaging.

I think so. We can discuss in the Core WG meeting.

from go-mod-messaging.

Nope, we can't until next major release. We have declared ZeroMQ as deprecated in Ireland and to be removed in future release, which has to be a major release.

from go-mod-messaging.

ZeroMQ is deprecated in Ireland and will be removed in future. No more development planned here
