SQS Queue

Amazon Simple Queue Service (SQS) provides fully-managed message queues that decouple and scale micro-services, distributed systems and serverless applications. A queue acts as a buffer, reliably storing any amount of messages until they are processed and deleted by consumers. Two delivery modes are available – standard (at-least-once, best-effort ordering) and FIFO (exactly-once, ordered). Queues can be encrypted, configured with dead-letter queues, and integrated with other AWS services such as Lambda or SNS.
For a comprehensive description see the official AWS documentation: https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/welcome.html

Terrafrom Mappings:

  • aws_sqs_queue.id

Supported Methods​

  • GET: Get an SQS queue attributes by its URL
  • LIST: List all SQS queue URLs
  • SEARCH: Search SQS queue by ARN

http​

Each SQS queue is identified by an HTTPS URL of the form https://sqs.<region>.amazonaws.com/<account-id>/<queue-name>. Overmind represents this URL as an http item, so the queue is linked to the corresponding http item that models the endpoint used by the AWS API.

lambda-event-source-mapping​

When a Lambda function is configured with an event-source mapping that pulls messages from an SQS queue, Overmind creates a lambda-event-source-mapping item. The mapping item is linked to the SQS queue it reads from, allowing impact analysis when either the queue or the Lambda configuration changes.
