This would have solved our problems in a recent demo. We would publish data and
it would work fine until we paused for a little while. I thought about putting
heartbeats in, but we don't really need to guarantee data (using PUB) or the
complexity (adding the heartbeat handling to all components)
Polling is supposed to be a non-busy wait so there should not be any CPU
usage while waiting on the sockets. I know this works on the Java version.

Yes, inproc works on Windows. You can use inproc between threads. The

HWM is related to the max

your process will eventually crash. Once it crashes, you lose all the

Here is the full code... You should be connecting to the sender and then
subscribing to all the messages.
Sender:
sender.bind("tcp://127.0.0.1:5559")
...
sender.send_json(message)
Device:
context = zmq.Context(1)
incoming = context.socket(zmq.SUB)
incoming.connect("tcp:
I would prefer that the HWM stay as the default. The application needs to be
built with the HWM in mind. If they don't explicitly set the value, they are
probably not considering it. There is also the challenge of knowing the proper
size that the HWM needs to be set based on the size of the mess
I'm not sure what you are seeing here are my test runs...

I ported the code to Java and it does not increase in memory. My guess
is that the clrzmq bindings are at fault.

If you use a payload encryption, you could pass out shared decryption keys
using a req/rep. If the filtering needed to change, you could detect it
(decryption fails) and the clients would then request a new decryption key. The
ones that are not allowed to see that data would be rejected.

I don't think the numbering actually matters (unless you really like the number
3). Numbering seems to be more of a marketing/political issue if it ever does
matter. I suspect the topic of breaking backwards compatibility and how to
handle it is more important. We will have this when we move fro
1 - 100 of 118 matches
