Apache Iceberg vs Grafana Loki
A side-by-side editorial comparison of Apache Iceberg and Grafana Loki — release velocity, themes, recent moves, and the top alternatives to consider.
Apache Iceberg vs Grafana Loki: at a glance
What is Apache Iceberg?
Iceberg 1.12 drops Spark 3.4 and starts laying groundwork for the v4 table spec.
Apache Iceberg maintains several minor lines at once, and most visible work is backports and dependency updates. 1.12.0 on September 30 is broader: it removes Spark 3.4 support, adds V4 groundwork such as relative paths in the spec and Parquet or Avro manifests, adds a REST unregister-table endpoint and content stats in the spec, and writes shredded Variant from Flink. Kafka Connect now reports commit failures instead of swallowing them.
What is Grafana Loki?
Loki 4.0 reaches RC3 and narrows S3 storage classes to Standard and Standard-IA.
Loki 4.0 is moving through release candidates. RC1's notes list the breaking changes: the V2 query engine unplugged, Simple Scalable Deployment targets and old /api/prom endpoints removed, protobuf as the default frontend encoding, and several deprecated settings and metrics dropped. RC2 removed every index backend but TSDB, and RC3 adds one more break, limiting S3 storage classes to STANDARD and STANDARD_IA, plus a compactor delete fix.

Apache Iceberg
0.0ANALYTICS
Iceberg 1.12 drops Spark 3.4 and starts laying groundwork for the v4 table spec.
◆ Current state
Apache Iceberg maintains several minor lines at once, and most visible work is backports and dependency updates. 1.12.0 on September 30 is broader: it removes Spark 3.4 support, adds V4 groundwork such as relative paths in the spec and Parquet or Avro manifests, adds a REST unregister-table endpoint and content stats in the spec, and writes shredded Variant from Flink. Kafka Connect now reports commit failures instead of swallowing them.
◆ Where it's heading
The project is moving from maintenance-only releases back to spec work, with V4 pieces landing in stages. Older engine versions are being dropped as that happens.
◆ Prediction
Expect more V4 spec and core pieces in 1.13 and patch releases on 1.11 and 1.12; a V4 release date is not visible in the entries.
Grafana Loki
6.3ANALYTICS
Loki 4.0 reaches RC3 and narrows S3 storage classes to Standard and Standard-IA.
◆ Current state
Loki 4.0 is moving through release candidates. RC1's notes list the breaking changes: the V2 query engine unplugged, Simple Scalable Deployment targets and old /api/prom endpoints removed, protobuf as the default frontend encoding, and several deprecated settings and metrics dropped. RC2 removed every index backend but TSDB, and RC3 adds one more break, limiting S3 storage classes to STANDARD and STANDARD_IA, plus a compactor delete fix.
◆ Where it's heading
Each candidate trims a bit more legacy surface, so 4.0 is a cleanup major that pushes installs onto TSDB and the microservices or single-binary layouts. The Operator had prepared this path since 0.11 and 0.12.
◆ Prediction
Expect a few more RCs with small breaking changes, then 4.0.0 GA and an Operator release that drops the removed schemas.
