Backport Prom 3.0 regex optimization change to mimir #9451

Open ywwg opened 1 day ago

In order to improve performance of dashboards with many template variables, we are planning to backport a specific change from Prometheus 3.0. This change is technically breaking so we are doing it carefully

Tasks:

[x] create metric to track affected users: https://github.com/grafana/mimir/pull/9400
[ ] metric deployed
[ ] analyze metric
[ ] backport PR for mimir-prometheus: https://github.com/grafana/mimir-prometheus/pull/702

task list may need updating for things like doing comms, etc
