Apache Iceberg vs OpenObserve
A side-by-side editorial comparison of Apache Iceberg and OpenObserve — release velocity, themes, recent moves, and the top alternatives to consider.
Apache Iceberg vs OpenObserve: 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 OpenObserve?
OpenObserve 1.2.0-rc2 is a long fix list that closes a cross-tenant write gap.
OpenObserve opened its 1.2 cycle with rc1, led by metrics v2: alerts created from charts, comparisons, forecasts, formulas and Prometheus 3.x functions. rc2 is a large batch of fixes across the new surfaces, including blocking cross-tenant writes through function updates and remote destinations, scoping service graphs and alert lists to what a user may read, and polish for an On-Call module now tagged beta. Fleet, RUM, Kubernetes and synthetics views also got fixes.

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.
OpenObserve
5.0ANALYTICS
OpenObserve 1.2.0-rc2 is a long fix list that closes a cross-tenant write gap.
◆ Current state
OpenObserve opened its 1.2 cycle with rc1, led by metrics v2: alerts created from charts, comparisons, forecasts, formulas and Prometheus 3.x functions. rc2 is a large batch of fixes across the new surfaces, including blocking cross-tenant writes through function updates and remote destinations, scoping service graphs and alert lists to what a user may read, and polish for an On-Call module now tagged beta. Fleet, RUM, Kubernetes and synthetics views also got fixes.
◆ Where it's heading
The 1.2 cycle is wider than metrics: rc2's fixes reveal on-call scheduling, fleet management, RUM, synthetics and incident root-cause features heading into the release. Several fixes tighten tenant and permission boundaries, which suggests multi-tenant and enterprise deployments are a priority before 1.2 goes stable.
◆ Prediction
Expect one more release candidate or a 1.2.0 stable soon, followed by 1.2.x backport patches as the 1.1 line had.
