serverless-plugin-sqs-from-sns

A serverless plugin to trigger a lambda from an automatically created SQS queue subscribed to an SNS topic.

Serverless enables lambda functions to be triggered from SNS or SQS. It is a common pattern to broadcast messages using SNS and to have them delivered to an SQS queue for lambda processing. This plugin automatically creates an SQS queue for each lambda function, and subscribes the SQS queue to the provided SNS topic. The lambda function is then triggered from the SQS queue.
