V2.9
Grafana Labs is excited to announce the release of Loki 2.9.0 Here’s a summary of new enhancements and important fixes:
Features and enhancements
Query Language Improvements: Several improvements to the query language that speed up line parsing and regex matching. PR #8646, PR #8659, PR #8724, PR #8734, PR #8739, PR #8763, PR #8890, PR #8914
Remote rule evaluation: Rule evaluation can now be handled by queriers to improve speed. PR #8744 PR #8848
Multi-store Index support: Loki now supports reading/writing indexes to multiple object stores which enables the use of different storage buckets across periods for storing index. PR #7754, PR #7447
New volume and volume_range endpoints: Two new endoints,
index/volume
andindex/volume_range
, have been added to Loki. They return aggregate volume information from the TSDB index for all streams matching a provided stream selector. This feature was introduced via multiple PRs, including PR #9988, PR #9966, PR #9833, PR #9832, PR #9776, PR #9762, PR #9704, PR #10248, PR #10099, PR #10076, PR #10047 and PR #10045New Storage Client: Add support for IBM cloud object storage as storage client. PR #8826
Block queries by hash: Queries can now be blocked by a query hash. PR #8953
logfmt stage improvements: logfmt parser now performs non-strict parsing by default which helps scan semi-structured log lines. PR #9626
Deprecations
- Legacy index and chunk stores that are not “single store” (such as
tsdb
,boltdb-shipper
) are deprecated. These storage backends are Cassandra (cassandra
), DynamoDB (aws
,aws-dynamo
), BigTable (bigtable
,bigtable-hashed
), GCP (gcp
,gcp-columnkey
), and gRPC (grpc
). See https://grafana.com/docs/loki/latest/storage/ for more information. - The
table-manager
target is deprecated, because it is not used by “single store” implementations. - The
-boltdb.shipper.compactor.*
CLI flags are deprecated in favor of-compactor.*

-ingester.unordered-writes
CLI flag is deprecated and will always default totrue
