Bug Fixes and Changes 🐛

• Added support for Kubernetes version 1.30 and 1.31

• New schema and store for Loki: The Loki configuration has been extended to add the new TSDB store and v13 schema. There are two new elements in the configuration (note: this is a breaking change):

  ...
  schema_config:
    ...
    - from: "2024-12-01"
      index:
        period: 24h
        prefix: index_
      object_store: s3
      schema: v13
      store: tsdb
  ...
  storage_config:
    ...
    tsdb_shipper:
      active_index_directory: /var/loki/index
      cache_location: /var/loki/cache
      cache_ttl: 24h
      resync_interval: 5s
      shared_store: s3

  The two pieces of new configuration introduced are:

  • The new schema config with TSDB and schema v13
  • The tsdb_shipper conf that configures the storage for TSDB

  The from in schema_config should be a string in ISO 8601 date format and it represents the day starting from which Loki will record logs with the new store and schema.

  ℹ️ Note: Loki will assume the start of the day on the UTC midnight of the specified day.

Breaking Changes 💔

• Loki store and schema change: A new store and schema has been introduced in order to improve efficiency, speed and scalability of Loki clusters.
