            How to properly handle with AMQP connections to and api with multiple producers
            Asked 2021-Jun-11 at 07:52

            I'm developing an api that communicates with other services from an event architecture using RabbitMQ Topics. Several routes from my API will publish events and I would like to have a single live connection at all times in my API. That way, at every new request I just create a new channel, and keep only one connection (I decided to do this after reading about how expensive an amqp 0-9-2 connection is).

            For now I have something like this:

            Is Pika thread safe?

            Pika does not have any notion of threading in the code. If you want to use Pika with threading, make sure you have a Pika connection per thread, created in that thread. It is not safe to share one Pika connection across threads, with one exception: you may call the connection method add_callback_threadsafe from another thread to schedule a callback within an active pika connection.

            so your solution can work with a single thread

            rasa 2.4 declares compatibility with Python 3.6, 3.7 and 3.8 but not 3.9 so pip is trying to find one compatible with 3.9 or at least one that doesn't declare any restriction. It finds such release at version 0.0.5.

            To use rasa 2.4 downgrade to Python 3.8.

            PS. Don't hurry up to upgrade to the latest Python — 3rd-party packages are usually not so fast. Currently Python 3.7 and 3.8 are the best.

            Easier way to use pika asynchronous (twisted)?
            Asked 2021-Mar-31 at 13:20

            This is my first project using rabbitmq and I am complete lost because I am not sure what would be the best way to solve a problem.

            The program is fairly simple, it just listen for alarms events, and then put the events in a rabbitmq queue, but I am struggling with the architecture of the program.

            If I open, publish and then close the connection for every single event, I will add a lot of latency, and unnecessary packages will be transmitted (even more than the usual because I am using TLS)...

            If I keep a connection open, and create a function that publish the messages (I only work with a single queue, pretty basic), I will eventually have problems because multiple events can occur at the same time, and my program will not know what to do if the connection to the rabbitmq broker end.

            Reading their documentations, the solution seems use one of their "Connection Adapters", which would fit me like a glove because I just rewrite all my connection stuff from basic sockets to use Twisted (I really liked their high level approach). But there is a problem. Their "basic example" is fairly complex for someone who barely considers himself "intermediate".

            In a perfect world, I would be able to run the service in the same reactor as the "alarm servers" and call a method to publish a message. But I am struggling to understand the code. Has anyone who worked with pika could point me a better direction, or even tell me if there is a easier way?

            Well, I will post what worked for me. Probably is not the best alternative but maybe it helps someone who gets here with the same problem.

            First I decided to drop Twisted and use Asyncio (nothing personal, I just wanted to use it because it's already in python), and even tho pika had a good example using Asynchronous, I tried and found it easier to just use aio_pika.

            I end up with 2 main functions. One for a publisher and another for a subscriber. Bellow is my code that works for me...

            Is Celery designed to run tasks that can execute when data is pushed in a RabbitMQ queue and consumed?
            Asked 2021-Mar-26 at 16:04
            Architecture

            I am planning to publish data from IoT nodes via MQTT into a RabbitMQ Queue. The data is then processed and the state needs to be saved into Redis.

            Current Implementation

            I spun up a docker container for RabbitMQ and configured it to enable MQTT (Port: 1883).

            Based on RabbitMQ's MQTT Plugin Documentation

            • Data from the MQTT Port is sent to amq.topic Exchange and subscribed to Queue Names similar to MQTT topics where / is replaced by . e.g. hello/test MQTT Topic -> hello.test RabbitMQ Queue.
            Basic Consumption via AMQP Port

            In short - no.

            Celery is not designed to process arbitrary data sent to a message queue system. It is designed to produce/consume messages that contain serialised Celery task details, so that consumers can execute particular task on the other end, and put the result into the result backend.

            However, I firmly believe almost any arbitrary message you can think of can be wrapped (this way or another) into a Celery task. The real problem though is when you do not want Celery on one of the ends (producer or consumer). Producers can send tasks without the ned to share code that contains task definitions using the convenient send_task() function.

            Why does publisher declares queue a in Pika RabbitMQ?
            Asked 2021-Feb-25 at 17:28

            I have gone through the fundamentals of RabbitMQ. One thing I figured out that a publisher does not directly publish on a queue. The exchange decides on which queue the message should be published based on routing-key and type of exchange (code below is using default exchange). I have also found an example code of publisher.

            ANSWER

            Answered 2021-Feb-25 at 11:31

            The consumer can declare the queue and bind it to the exchange when the consumer connects to RabbitMQ. A fanout exchange then copies and routes a received message to all queues bound to it, regardless of routing keys or pattern matching as with direct and topic exchanges.

            So no, the publisher does not have to be aware of all queues bound to the exchange. However, the publisher can ensure that the queue exists to ensure that the code will run smoothly, but that is of more importance for other exchange types.
