How do I set up priority queuing by separating messages into multiple SQS queues?

When you need to prioritize messages in a messaging system, separating them into multiple queues is a practical approach. In this example, we’ll set up an AWS SQS (Simple Queue Service) configuration with multiple queues to handle different priority levels. We’ll create three queues: high-priority, medium-priority, and low-priority. This setup will allow you to send urgent messages to the high-priority queue, less urgent messages to the medium-priority queue, and non-urgent messages to the low-priority queue.

Here’s a detailed description of the components:

1. AWS Provider: Configure the AWS provider to interact with your AWS account.
2. SQS Queues: Create three separate SQS queues for high, medium, and low priorities.
3. Outputs: Export the ARNs (Amazon Resource Names) of the queues for further use in your infrastructure or applications.

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

const highPriorityQueue = new aws.sqs.Queue("high_priority_queue", {
    name: "high-priority-queue",
    visibilityTimeoutSeconds: 30,
});
const mediumPriorityQueue = new aws.sqs.Queue("medium_priority_queue", {
    name: "medium-priority-queue",
    visibilityTimeoutSeconds: 30,
});
const lowPriorityQueue = new aws.sqs.Queue("low_priority_queue", {
    name: "low-priority-queue",
    visibilityTimeoutSeconds: 30,
});
export const highPriorityQueueArn = highPriorityQueue.arn;
export const mediumPriorityQueueArn = mediumPriorityQueue.arn;
export const lowPriorityQueueArn = lowPriorityQueue.arn;

In this setup, we created an AWS provider targeting the us-east-1 region. Then, three SQS queues named high-priority-queue, medium-priority-queue, and low-priority-queue were configured, each with a visibility timeout of 30 seconds to ensure that once a message is being processed, it remains invisible to other processes for the specified duration. Lastly, we exported the ARNs of these queues, which can be useful for referencing these queues within other parts of your infrastructure.

This configuration helps in effectively managing message prioritization by segregating messages based on their urgency into distinct queues.
