This document describes using a Lambda function triggered by an S3 event to automatically load JSON data from an S3 bucket into a DynamoDB table. The Lambda function is configured with layers including the Pandas library and an IAM role with permissions to access S3 and DynamoDB. When a file is uploaded to the S3 bucket, the Lambda function is triggered, reads the JSON data, and adds items to the DynamoDB table which is monitored through Cloudwatch logs.
