説明

The documentation about retention states that logs are only deleted if a lifecycle storage policy on the store deletes it, however, the documentation doesn't specify what that policy should look like.

For instance:

  1. What is the significance of the loki_cluster_seed.json file at the root of the container? (A blanket delete after x days policy would automatically delete this as well)
  2. Are files in /index meant to be deleted, or should it just be limited to /<orgId> or /fake

調査方針
Examine the current retention documentation at the provided URL to understand what is already stated. Look at the Loki source code to understand the significance of 'loki cluster seed.json' and the index files. Check for any existing issues or discussions about lifecycle policies. Then propose updates to the documentation to clarify the required lifecycle policy, addressing the specific questions about the seed file and index directory.
