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 OpenMetadata?

OpenMetadata reaches 2.1 rc1 after a month of repairing 2.0's connectors.

OpenMetadata has shipped a run of 2.0.x maintenance releases, each centered on connectors, lineage and search. 2.0.3 included a certificate-verification bypass fix and a SQL-injection fix, 2.0.5 restored metadata affected by 2.0 ingestion regressions, and 2.0.7 improved reliability for Pub/Sub, SQL Server and Unity Catalog. The 2.1.0-rc1 pre-release has now appeared, though its notes are a commit message about settings-modal styling rather than a feature list.

Apache Iceberg vs OpenMetadata: editorial side-by-side

A0.0

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.

5.0

OpenMetadata reaches 2.1 rc1 after a month of repairing 2.0's connectors.

◆ Current state

OpenMetadata has shipped a run of 2.0.x maintenance releases, each centered on connectors, lineage and search. 2.0.3 included a certificate-verification bypass fix and a SQL-injection fix, 2.0.5 restored metadata affected by 2.0 ingestion regressions, and 2.0.7 improved reliability for Pub/Sub, SQL Server and Unity Catalog. The 2.1.0-rc1 pre-release has now appeared, though its notes are a commit message about settings-modal styling rather than a feature list.

◆ Where it's heading

The 2.0 launch is being paid for in connector repairs, and the cadence of roughly weekly maintenance suggests a large installed surface. Protecting user-managed metadata from bot ingestion, and multi-pod fixes in 2.0.6, point at production deployments rather than trials. The 2.1 candidate is the first sign of attention moving forward, but the published notes do not show its contents.

◆ Prediction

Expect a 2.1 release soon, with its real scope clearer once proper notes appear. 2.0.x maintenance should continue alongside it.
