This pattern demonstrates how a Lambda function can get triggered when there is a new event in a DynamoDB stream using filters.
For this example, a new event in a DynamoDB stream triggers a Lambda function based on a filter. The created stack has one DynamoDB table with streams enabled and 4 Lambda functions configured with ESM filters:
1. Bachelors Lambda (process-bachelors-request) - Triggers for every insert of Bachelors Record
2. Masters Lambda (process-masters-requests) - Triggers for every insert of Masters Record
3. Modify Lambda (process-modify-request) - Triggers for any updates
4. Delete Lambda (process-delete-request) - Triggeres for any remove
