Can a file uploaded to an EFS folder trigger Lambda to upload to S3?

Serverless Framework

I’ve created a Lambda function that can be triggered by an S3 file upload to a certain bucket and then downloads that file to EFS. I was wondering if the opposite workflow is possible, such that, a file uploaded to a given EFS directory would trigger Lambda to upload that file to S3?

For instance, in the serverless.yml template, the event for the former set up would be event: s3:ObjectCreated:*, but is there an equivalent for EFS?

Hello, at the moment you cannot use EFS as an event source for Lambda.
