hello, I was wondering if prefect had a way to interact with an AWS SNS queue. We are trying to detect the presence of a file to kick off a job. One solution is to have the flow check every 30 min or so and then delete the processed file, but I was wondering if there was a more elegant solution out there

Hi @Alex Welch - check out this blog post by Chris; it describes using AWS Lambda to create event-driven workflows by triggering Prefect Flow runs through the GraphQL API. I think this is primarily what you're asking about here with some tailoring for AWS SNS (with which I'm not super familiar, apologies!)

awesome! I’ll take a look
