Preventing Amazon DynamoDB write throttling with an Amazon SQS queue-based buffer
This code demonstrates how an Amazon SQS queue can be used to buffer records for an Amazon DynamoDB table and mitigate the risk of a client of being throttled.
The SAM template deploys ingress and dead-letter queues, a Lambda function, and the destination DynamoDB table.
The Lambda function will use a partial batch response to return throttled records back to the queue.
The function uses Node.js 18 runtime running on ARM64 processors powered by AWS Graviton.
