Morning ! We run open-source prefect on-premise, is there a way to have event-driven pipelines (as opposed to scheduled ?), lets say run the pipeline when there are new files in a s3 bucket ?

Hi @Prasanth Kothuri - Not on open source I'm afraid. If you're able to switch to Prefect Cloud, you could use AWS Lambda with our new Prefect cloud webhook feature (and deployment triggers) to kickoff a flow when new files are added.
