| So your client just sucks here. My experience with the eclipse clients (paho, etc) is similar to yours in both python and C++, - it makes it overly complicated and seems very low level. It also is somewhat buggy because of the architecture. I believe (perhaps wrongly), it's all basically maintained by one person or close to it (only one person has contributed to the C++ client in the past 6 months, for example, and nobody has contributed in the past 3), so i kind of understand how it's gotten this way over time. I filed a simple PR (1 word change) to fix an obvious bug and it took 2 years to review it and accept it with no changes. Again not a complaint, just trying to portray how the state feels - a lot of libraries, bugs, and work, and few overworked people helping get it all done. I moved to other clients and the experience is much much better in python, rust, C#, and C++. Most of them have a good combination of high and low level API's, so if you just want to send a message on a topic, you don't have to worry about acks, retries, etc. But if you need control, you can get it. Honestly, i worry at this point that keeping paho/etc alive in this state is doing more harm than good - if they were officially dead it would at least force the issue.
Right now you end up with users who have an experience like yours, and then either give up on MQTT or assume they are doing it wrong :) |
