QUESTION

Create and cleanup instance specific rabbitMQ instances

Asked 2022-Apr-15 at 16:36

I have a set of microservices using springboot rest. These microservices will be deployed in a autoscaled and load balanced environment. One of these services is responsible for managing the system's configuration. When other microservices startup, they obtain the configuration from this service. If and when the configuration is updated, I need to inform all currently running microservices instances to update their cached configuration.

I am considering using RabbitMQ with a fanout exchange. In this solution, each instance at startup will create its queue and bind that queue to the exchange. When there is a configuration change, the configuration service will publish an update to all queues currently bound to that exchange.

However, as service instances are deleted, I cannot figure out how would I delete the queue specific to that instance. I googled but could not find a complete working example of a solution.

Any help or advise?

The idea and solution is correct. What you just miss that those queues, created by your consumer services could be declared as auto-delete=true: https://www.rabbitmq.com/queues.html. As long as your service is UP, the queue is there as well. You stop your service, its consumers are stopped and unsubscribed. At the moment the last consumer is unsubscribed the queue is deleted from the broker.

On the other hand I would suggest to look into Spring Cloud Bus project which really is aimed for tasks like this: https://spring.io/projects/spring-cloud-bus.

I want to know do we need to create three different queues to deliver message to three different consumer? Like here I have created 3 queues and bind it to the fanout exchange and then I in publisher class I am passing list of Product Model from POSTMAN and I am creating 3 consumer for that.

No.

In amqp, if you need the same message to be received by multiple consumers, you'd need need multiple queues.

A queue could be shared by many consumers but then each consumer would get its share of messages in a round-robin fashion (useful for distributed workers).

The tutorials at https://www.rabbitmq.com/getstarted.html should clarify these concepts, especially the # 3, titled "Sending messages to many consumers at once".

QUESTION

Is it possbile to publish one SNS Topic to another?

Asked 2022-Mar-17 at 23:57

I have a requirement where my application, in AWS account A, needs to broadcast that a new resource is created, to AWS accounts: B, C and D.

I was thinking of implementing a solution, where an SNS Topic in Account A, publishes to SQS Queues Accounts: B, C and D (FanOut Pattern).

Question: Is it possible to use SNS Topics in account B, C and D rather than SQS Queues? Basically, is it possible to subscribe one SNS Topic to another?

I was not able to find anything that concretely answered the question.

ANSWER

Answered 2022-Mar-17 at 23:57

No. Amazon SNS is not an available subscription type.

You could subscribe an AWS Lambda function and that Lambda function could send messages to desired SNS topics.

MassTransit consumed on single server

Asked 2022-Mar-07 at 14:12

I am struggling to configure MassTransit with RabbitMQ to publish messages and subscribe to the queue. I think that its a simple configuration change that needs to be done. I have multiple services connected but the messages get consumed alternatively and never gets delivered / consumed on the other server.

I would like each message to get delivered to every connection / subscriber.

I am running this on ASP.net core 6 on the latest version of MassTransit.

Argo Workflow to continue processing during fan-out

Asked 2022-Feb-03 at 14:15

General question here, wondering if anyone has any ideas or experience trying to achieve something I am right now. I'm not entirely sure if its even possible in the argo workflow system...

I'm wondering if it is possible to continue a workflow regardless if a dynamic fanout has finished. By dynamic fanout I mean that B1/B2/B3 can go to B30 potentially.

I want to see if C1 can start when B1 has finished. The B stage is creating a small file which then in C stage I need to run an api request that it has finished and upload said file. But in this scenario B2/B3 still are processing.

And finally, D1 would have to wait for all of C1/2/3-C# to finish to complete

I am attempting to declare a Queue on my RabbitMQ broker. I had no issue before this until I tried adding "auto_delete=True" parameter to the queue declaration. The Queue is meant to consume messsages from a fanout Exchange.

I have already deleted the Queue before declaring it again. I even tried renaming the Queue. Nevertheless, I keep receiving the same error "PRECONDITION_FAILED - invalid property 'auto-delete' for queue 'test.queue' in vhost '/'". Below is my code for declaring the queue:

Use a larger datatype to shift the values out of the way. This is similar to the first example without the potential for collisions. It probably also has minor performance benefits in not having to execute two different distinct sums.
