Lambda invokes another Lambda asynchronously. If payload exceeds the quota, it is saved to S3 which triggers the second Lambda.
This sample project demonstrates how to use a Lambda function to invoke another Lambda function asynchronously.
The AWS SAM template provided deploys two Lambda functions. First Lambda function invokes second Lambda function asynchronously.
When the payload size exceeds the invocation payload size quota, then payload is saved to an Amazon S3 bucket.
S3 bucket `s3:ObjectCreated` event triggers second Lambda function.
Using Lambda function asynchronous invocation saves time and cost.
