Can I have Interprocess Communication with Django Channels?
I am building an architecture where I have several Services that runs in parallel, one of them serves the client application, which communicates through Websockets, call it Frontend. I choose Django with Channels for its implementation. I have another service (implemented in Python too) that needs to communicate with the Frontend, I need to do it through network sockets using a simple custom protocol. How can I integrate those services that way? I took a look at the Cross-Process Communication docs but I did not figured out how to do it. Can I push messages to a channel from any Python process? -

How to prevent Throttling issue with celery workers?
I want to build script to pull data from amazon api, interesting thing in amazon api that they have strict Throttling rules by different endpoints, e.g.: Maximum request: quota 30 requests Restore rate: One request every two seconds Hourly request quota: 1800 requests per hour So for one account we can do 30 requests at one time without throttling, but not more than 1800 per hour. Restore rate means - that after we did 30 requests at once we have to wait 60 seconds(2 seconds * 30 request) to make again 30 requests at once. First I wanted to implement that with celery, but in this case need to use global lockers, which seems isn't best solution, and hard to maintain. In nodejs worlds we can use something like https://www.npmjs.com/package/bottleneck. const limiter = new Bottleneck({ maxConcurrent: 1, minTime: 333 }); limiter.schedule(() => myFunction(arg1, arg2)) .then((result) => { /* handle result */ }); Any similar libs in python, or maybe just good suggestion how to implement that, with ability to monitor, and reschedule if fail. -
