Vector databases for real-time risk — overkill or worth it?

I’m researching this for a project and would love real-world input. If you’ve built or shipped something here, what did you learn? Context: I’m Laura King and I’m evaluating options for our team.

    Run a pre-mortem; it surfaces surprises early. Quick checklist that saved us time. Rotate credentials on a calendar, not only after incidents.

    We phased traffic: 5% → 25% → 60% → 100% to de-risk. Document assumptions so new teammates move faster. Two cents after running this through prod traffic.

    Train support to recognize false positives quickly. Quick checklist that saved us time. Make alerting boring and reliable.

    We hit rate limits on day three; lightweight caching saved us. Tighten feedback loops with weekly reviews. We learned this the hard way during a vendor swap.
