Is it possible to persistently annotate/attach metadata to a successful deployment run in Prefect with metadata or should I use storage for that? We use Prefect to asynchronously launch a short-lived workflow (<1min) from a Node.js backend. This allows us to free the Node.js backend from being blocked. The output of this workflow is a simple JSON with an array of key-value pairs. We would like to be able to return the result of this JSON in the simplest possible way. What’s the best practice here? AFAICT there are 3 options: 1. Persist the result into a database from the workflow 2. Persist the result into a storage 3. Annotate the deployment run / attach metadata to the deployment run using Prefect SDK If option (3) exists it would be great, less responsibilities on the application side of things to setup the database, persist the data and then apply garbage collection to stale data (e.g. when deployments get deleted, we need to do a cascaded delete where the JSON body also needs to be wiped out). Your thoughts? Thanks!

You can also attach a callback function to the flow run, so after it finishes you could have it post data to a node endpoint

Sure but what happens if this node dies?

Ah yeah that Makes sense

There’s works being done on this front. PRs you can follow here: https://github.com/PrefectHQ/prefect/pull/8645 https://github.com/PrefectHQ/prefect/pull/8759

Thanks Jeff, what an interesting timing!

Hi Ofir. I know they are being actively worked on and will be added to a release as soon as they are ready. 🙂

Gotcha thanks!
