Hi Alan,
Do you have any plans to introduce any kind of compatibility layer for
zmq
in the future? Or do the protocols diverge so much that it's
untenable?
I think it's technically doable. nanomsg has pluggable transports (see
the API here:
https://github.com/250bpm/nanomsg/blob/master/src/transport.h) so adding
a new one is not that big a problem. Say zmq://, which would emulate
0MQ's TCP wire format.
The transport would have to re-shuffle the header fields of the
messages so that the layers on top of it are fooled to believe that the
layering is done in the correct order.
That being said, there are nanomsg features that don't exist in 0MQ
(such as new messaging patterns, or new types of subscriptions) which
won't be accessible from 0MQ peers. Also, 0MQ features that were
deprecated in nanomsg (e.h. ZMQ_IDENTITY) won't be accessible from
nanomsg peers.
If anyone is interested in implementing this kind of transport, I'd be
happy to provide advice and help in general.
Martin
