Preventing Amazon DynamoDB write throttling with an Amazon SQS queue-based buffer using CDK and monitoring with CloudWatch alarms.
This code demonstrates how an Amazon SQS queue can be used to buffer records for an Amazon DynamoDB table and mitigate the risk for a client of being throttled.
The CDK code deploys Ingress and Dead-Letter SQS queues, AWS Lambda functions, destination DynamoDB tables and CloudWatch alarms.
AWS Lambda function uses NodeJS 20 runtime.
