v3.4

Grafana Labs and the Loki team are excited to announce the release of Loki 3.4. Here’s a summary of new enhancements and important fixes.

For a full list of all changes and fixes, refer to the CHANGELOG.

Features and enhancements

Key features in Loki 3.4.0 include the following:

  • Time sharding ingestion: Add per-tenant time sharding for long out-of-order ingestion. The setting shard_streams.time_sharding_enabled is a per-tenant config that splits incoming log streams by injecting a new __time_shard__ synthetic label in such a way that no stream will ever be longer than 1h (or, rather, max_chunk_age/2). This allows the ingestion of very old logs, because the logs in these new streams will never be “too far behind” by design. (#14711) (0d6d68d).

  • Thanos object client: Previously Loki and Grafana Enterprise Logs used different Go packages to talk to the underlying object store. Migrating to Thanos means that there is now a single object client across Loki and GEL, and across the other Grafana backend databases: Mimir and Pyroscope.(#14891) (fb6789d), (#14638) (8958eb9), (#14867) (947a66f), (#14793) (cfc3819), (#14937) (a629212). The documentation now includes configuration examples using Thanos-based storage clients.

  • API: Add support for Parquet file format as a query response format. (#15408) (d0c11a6).

  • Structured metadata: Introduces a new feature,based on per-tenant configuration, that allows for extraction of “fields” into structured metadata at ingest time. Fields can either be regular labels, structured metadata keys, or keys from logfmt or json formatted log lines. (#15188) (7033091).

  • lambda-promtail: Adds support for relabeling log entries in lambda-promtail using Prometheus-style relabel configs. This allows for more flexible label manipulation and filtering of log entries before they are sent to Loki. (#15600) (c41a8b4).

  • Kafka: Loki 3.4 adds an Apache Kafka development environment to support ongoing development work(#15603) (226e9f1).

  • Helm charts: Loki 3.4 includes multiple improvements to the Helm charts, including: Added support for overrides exporter (#15630) (db72164), Expose topologySpreadConstraints for admin-api pods (#14995) (1b93086), Expose topologySpreadConstraints for distributed deployment (#14853) (d075107), Compute ConfigMap/Secret checksum only over .data content (#15177) (990f71c), Do not explicitly template managed-by, as it should be set at install time by the installation manager. (#14763) (10b7478).

  • Query acceleration with Bloom filters (experimental): The Bloom filters feature introduced in Loki 3.0 remains experimental. In Loki 3.3, there was a major shift in how Loki leverages bloom filters — pivoting from free-text search to harnessing the power of structured metadata. In Loki 3.4, work continues on the new Bloom Planner (#14874) (b646861).

  • Explore logs: The Explore apps suite for metrics, logs, traces, and profiles has a new name: Grafana Drilldown. To learn more about why we made this switch, you can read about it in this blog post. The new name is reflected in the Grafana Cloud user interface and navigation as of 2025-02-20, and it will be part of the Grafana 11.6 release in March.

  • Docs: This release includes a heavily revised labels topic and a new Cardinality topic. This release also marks the return of the sizing guidance page, newly updated based on Grafana Labs experience running Loki. Continuing updates to the Query section include a revised logcli topic and new logcli tutorial. There is also two additional new tutorials: Deploying Loki on Azure tutorial and Kubernetes Monitoring Helm tutorial.

Note

Note that when appropriate, documentation updates have been backported to previous releases.

Other improvements include the following:

  • analytics: Add TLS config to the analytics client (#15227) (2c5eabd).
  • approx_topk: Reduce memory usage of HyperLogLog in approx_topk. (#15559) (bef2043).

  • querier: Present DF bytes values in queryable format (#15272) (f5d62bd).
  • querier: Use context propagation to call the same ingester in GetChunksID as Query (#15186) (70d9587).
  • ruler: Add Rule Name and Type to Query Tags (#15055) (b272573).
  • storage: Add objstore support for Swift using thanos.io/objstore (#11672) (44523e0).
  • storage: Skip writeback for chunks fetched by queriers older than a duration (#15605) (3b8d993).
  • storage: Support config timeout for AlibabaCloud OSS requests (#14856) (ac2e21f).
  • storage: Allow TSDB index creation in memory only (#14732) (831c0d5).
  • structured metadata: Sanitize structured metadata during ingestion in the distributor (#15141) (be4f17e).

3.4.5 (2025-07-11)

  • storage: Add a configuration option for custom GCS endpoints (#16419) (#18419) (b2c87ba).

Deprecations

One of the focuses of Loki 3.0 was cleaning up unused code and old features that had been previously deprecated but not removed. Loki 3.0 removed a number of previous deprecations and introduces some new deprecations. Some of the main areas with changes include:

  • Promtail is deprecated, as the code has been merged into Grafana Alloy. You can find migration documentation and a utility to convert your Promtail configuration to Alloy configuration in the Alloy documentation. Note that this deprecation does NOT include the lambda-promtail client.

  • Deprecated storage options including the deprecation of the BoltDB store.

  • Deprecated configuration options.

  • API endpoint deprecations.

To learn more about breaking changes in this release, refer to the Upgrade guide.

Caution

Grafana Alloy is the new name for our distribution of the OTel collector. Grafana Agent has been deprecated and is in Long-Term Support (LTS) through October 31, 2025. Grafana Agent will reach an End-of-Life (EOL) on November 1, 2025. Read more about why we recommend migrating to Grafana Alloy.

Upgrade Considerations

For important upgrade guidance, refer to the Upgrade Guide.

  • BREAKING CHANGE - Docker image: Remove wget from Promtail docker image (#15101).
