[workloadmeta/store] Fix filters that match entities #27151

Closed davidor closed 5 days ago

davidor commented 5 days ago

What does this PR do?

Fixes a bug in the workloadmeta store. It was not working correctly for filters that match entities, like workloadmeta.IsNodeMetadata used by the metadata controller.

I've set the no-changelog label because this doesn't affect any released versions.

Describe how to test/QA your changes

Skip. It's a bit difficult to test this case manually, but I added a unit test that should cover it.

Explanation

A regression test is an A/B test of target performance in a repeatable rig, where "performance" is measured as "comparison variant minus baseline variant" for an optimization goal (e.g., ingress throughput). Due to intrinsic variability in measuring that goal, we can only estimate its mean value for each experiment; we report uncertainty in that value as a 90.00% confidence interval denoted "Δ mean % CI". For each experiment, we decide whether a change in performance is a "regression" -- a change worth investigating further -- if all of the following criteria are true: 1. Its estimated |Δ mean %| ≥ 5.00%, indicating the change is big enough to merit a closer look. 2. Its 90.00% confidence interval "Δ mean % CI" does not contain zero, indicating that *if our statistical model is accurate*, there is at least a 90.00% chance there is a difference in performance between baseline and comparison variants. 3. Its configuration does not mark it "erratic".
