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 2.0.8 widens Hex, Sigma and BigQuery coverage while 2.1 waits in release candidates.

OpenMetadata is still in 2.0.x maintenance mode, shipping a release every one to two weeks. 2.0.8 on November 13 is the broadest yet: Hex and Sigma ingestion now build data models and column lineage, BigQuery date-sharded tables can be grouped into one logical table, Power BI and Snowflake ingestion stop leaving stale or runaway jobs, and MCP authentication and access controls were tightened. The 2.1.0 line sits at rc2, whose only published change is a tag-resolution fix.

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.

ANALYTICS
5.0

OpenMetadata 2.0.8 widens Hex, Sigma and BigQuery coverage while 2.1 waits in release candidates.

◆ Current state

OpenMetadata is still in 2.0.x maintenance mode, shipping a release every one to two weeks. 2.0.8 on November 13 is the broadest yet: Hex and Sigma ingestion now build data models and column lineage, BigQuery date-sharded tables can be grouped into one logical table, Power BI and Snowflake ingestion stop leaving stale or runaway jobs, and MCP authentication and access controls were tightened. The 2.1.0 line sits at rc2, whose only published change is a tag-resolution fix.

◆ Where it's heading

Each 2.0.x release repairs connectors and lineage that 2.0 left incomplete, and the fixes increasingly touch accuracy (correct table identity, lineage that ends at the right model) rather than crashes. MCP keeps appearing in the security sections, which suggests OpenMetadata expects AI tools to read the catalog and is locking that path down before 2.1.

◆ Prediction

A 2.1.0 final is the next visible step, since two release candidates are out; the entries do not yet say what features 2.1 adds beyond the fixes backported to 2.0.x.
