A few questions about schema_config

Hello,

I have been wondering about schema_config (especially for S3 but also generally) and I have a few questions.

E.g. the example config on this page

schema_config:
  configs:
    - from: 2018-04-15
      store: boltdb-shipper
      object_store: gcs
      schema: v11
      index:
        prefix: loki_index_
        period: 24h

Is the from and schema (the version) something that is versioned upstream for Loki or are these for my own versioning of my specific schema?
If it is the first one, where can I find a list of the schemas?
If it is the second, I assume these need to always be incremented when you make changes?

Just found Storage | Grafana Labs
