DynamoDB does not have built-in triggers, but you can use AWS Lambda functions to create triggers that respond to changes in a DynamoDB table. A Lambda function can be triggered by various AWS services, including DynamoDB, S3, SNS, and SQS, which allows you to create custom logic that runs in response to changes in a DynamoDB table.
You can use the DynamoDB Streams feature to capture data modification events in a DynamoDB table. A stream is an ordered flow of information about changes to items in a DynamoDB table. By combining DynamoDB Streams and Lambda, you can create a trigger that runs a Lambda function when data is added, modified, or deleted in a DynamoDB table.
