@flanakin, the recommendations table schema is very specific to the Cost Management commitments recommendations. Ideally, we would merge Advisor + custom ARG-based recommendations into the same table, but the schema must become generic enough to accommodate them. See a more generic recommendations schema suggestion in the hack24 branch. The ADF pipeline for exporting these recommendations is ready and has been thoroughly tested. It would be great if we launch everything together. Let's discuss a common schema for Advisor-like and ACM recommendations.

Yes, I know. I was going to merge with the other one, but didn't want to take even longer to get the foundational work done when I didn't have a full understanding of needs coming from other recommendations. I figured we'd do that as part of bringing in Advisor recommendations. Let me know if you see anything concerning.
