Dylan Guedes 5c8e832260 feat: Introduce policy stream mapping (#15982) ... **What this PR does / why we need it**: Introduces the idea of policies to Loki, which are recognizable based on the given stream selectors. This is an improved version of https://github.com/grafana/loki/pull/15561 and built on top of https://github.com/grafana/loki/pull/15875. A policy mapping can be configured the following way: ```yaml 12345: policy_stream_mapping: policy6: - selector: `{env="prod"}` priority: 2 - selector: `{env=~"prod|staging"}` priority: 1 - selector: `{team="finance"}` priority: 4 policy7: - selector: `{env=~"prod|dev"}` priority: 3 ``` With that configuration, pushes to tenant `12345` with the labels `{env="prod", team="finance"}` would be assigned to policy6 because the third mapping for policy6 matches these labels and has higher priority than any other matching.		3 months ago
