sqs-test-ts

Testing launching a Lambda from AWS SQS and a naive Request-Response Messaging Pattern implementation.

NOTE

This is not production code, it doesn't work with concurrency, there is currently no implementation for SQS Virtual Queues on AWS SDK JS. Check Request-Response Messaging Pattern (Virtual Queues)

Diagram

1. User sends a request to jobSubmit
2. It then published to sqsTestTsQueue
3. Worker listen to sqsTestTsQueue and process the job
4. Then publishing results to sqsTestTsQueueResult
5. User can periodically check for results using jobResult endpoint, which checks sqsTestTsQueueResult for results.
