@Marvin How can I trigger a workflow to run when a new file is uploaded to a s3 bucket?

It looks like there isn't a direct example in the Prefect documentation for triggering a workflow when a new file is uploaded to an S3 bucket. However, based on a related concept from blog posts, you can potentially use a combination of AWS CloudWatch and AWS Lambda in conjunction with Prefect's webhook to accomplish such a trigger. You can create an AWS Lambda function that is triggered by a CloudWatch event. This event can be configured to be triggered when a new file is uploaded to an S3 bucket. When the Lambda function is invoked, it can post a request to a Prefect webhook, which in turn triggers the workflow (or flow) you have in Prefect. For more detailed reference on how AWS services can interact with Prefect and the concept of using webhooks, see the articles below: - Prefect with GitHub Actions and schedule - Prefect with CloudWatch logs Please note that you would need to properly configure AWS Lambda, CloudWatch, and the Prefect webhook for this to work effectively.
