Hey folks! How are you accessing Asset Metadata in your Custom IO?

Hi Sean. If you're referring to fetching runtime metadata that has that is persisted via

handle_output

, you currently cannot fetch it within the

handle_output

call. You can however query the instance for past asset materializations that have already occurred. We have an issue documenting this: https://github.com/dagster-io/dagster/discussions/6913

Hi, I am trying to achieve a similar thing... I have a custom I/O manager and in my

load_input

I can perfectly access the metadata of an asset like this

context.upstream_output.metadata.get
