I think you might find that gets prohibitively expensive at scale. There's various definitions of "semantic", such as building indexes on OTel semantic conventions, all the way over to true semantic search over data in attributes. I'd be curious how you're thinking about this at the scale of several millions of traces per second.
Hey there, by semantic we mean, embedding text and storing it in the vector DB. Regarding scale, we thought a lot about it, and that's why we process span in the background queue. Tradeoff would be that indexing / embedding would not be real-time as scale will grow. We will also use tiny embedding models, which become better and better.
