Loki - What is the performance enhancement of schema version v12 compared with v11


I am looking for an article comparing Loki schema version v12 vs v11, But can not find any.
I’m curious about what is the performance improvement of v12 compared with v11.
Hope you can help me with my curiosity.

Thank in advance!

I can’t find anything in the doc either, but this seems to be the pull request for the v12 schema: https://github.com/grafana/loki/pull/4857

Seems to be an S3 performance related change.
