This sets a metrics retention limit at 30 days in your s3 storage. This may be too short or too long dependent on your specific use cases. This retention policy can be overwritten by using the following values in your values.yaml file:

compactor:
  retentionResolutionRaw: 30d
  retentionResolution5m: 30d
  retentionResolution1h: 10y
