I have found OPA to be a fairly reliable and performant system in production. We were able to build a scalable RBAC solution that used OPA as evaluators. We had around 40k OPA instances serving around 350K qps with p99.9 hovering around 6ms.

~9qps per instance doesn't sound all that impressive unless there's more context to it?

The policy bundle were sharded and cached on the client side, so the QPS itself was not much of an impressive data point on the OPA front. On the cache side we were seeing a lot more traffic, ~2B qpm (queries per minute) on daily peaks and p99.9 around 20 us.

Unless “instance” means something different in this context? Policy?
