  Out of all the projects/products on this list, we've found Victoria Metrics to be by _far_ the best.

  This summary makes it seem like Victoria Metrics is barely compatible with Prometheus, but that can't be further from the truth in practice.

  Prometheus can't even do bulk import.

  How do you include that in a CI/CD environment with regression testing?

  This is great -- thanks for putting it together! Will these be kept up-to-date? If so, what will the cadence be?

  VictoriaMetrics CTO here.

  These tests are great, because they spotted a few minor bugs in our PromQL implementation and these bugs were fixed quickly. See https://victoriametrics.github.io/CHANGELOG.html .

  The majority of failed tests for VictoriaMetrics cannot be "fixed" due to deliberate choice made when designing MetricsQL: to rethink and to fix the most annoying and confusing parts of PromQL, while providing drop-in PromQL replacement for the majority of practical cases.
