Hi folks - I'm looking to build an index of workflow outputs, but have a couple of questions to resolve. I need a way of indicating what outputs those are exactly. • By convention,

end_node

is possible.. but it's not flexible enough. • Anything in the type system should be marked as indexable, so using a specific custom type won't fit. • I see that LiteralType has both

metadata

and

annotations

fields. Would either be appropriate? I see that

Annotated

is used to generate custom hash keys for cached outputs, so I thought something like this might work more generically:

Copy code

@workflow
def training_workflow() -> Annotated[LogisticRegression, "IndexMe"]:

However, looking through my S3 bucket protobuf files I don't see anything there. Thanks!

Follow-on question, assuming what I'm interested in is possible: Is there a pluggable way to extend Flyte to index these files as they're generated / written? Rather than setting up a batch job to process outputs / index them after they've been written to blob storage, it would be great to be able to hook into Flyte to do it in real time. Any thoughts on the right way to do this?

@freezing-airport-6809 I just stumbled on https://github.com/unionai-oss/artifact-demo and it looks like you're building out a first class

Artifact

concept already which might do the things I'm looking for. I also see the PR at https://github.com/flyteorg/flyte/pull/4077. Anything further to disclose here yet on direction / roadmap?

also, what you need is also available as an event stream, but artifacts takes it to the next level

Ah, that's great / exciting news! I will be following this space pretty closely then -- it looks like what you have in mind is pretty well aligned with what I was thinking.
