Delta Lake vs OpenMetadata
A side-by-side editorial comparison of Delta Lake and OpenMetadata — release velocity, themes, recent moves, and the top alternatives to consider.
Delta Lake vs OpenMetadata: at a glance
What is Delta Lake?
Delta Lake's public stream is Databricks builds and code cleanup on the way to 4.5.
Recent Delta Lake activity is release mechanics. The newest entries are a Delta Kernel 4.5.0 Databricks build, the removal of unused V2 streaming snapshot code, and CI changes that pause idle source-build jobs now that Spark 4.0 to 4.3 use published artifacts. The last user-facing fix in the window is still 3.3.3's log cleanup correction.
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.

Delta Lake
5.0ANALYTICS
Delta Lake's public stream is Databricks builds and code cleanup on the way to 4.5.
◆ Current state
Recent Delta Lake activity is release mechanics. The newest entries are a Delta Kernel 4.5.0 Databricks build, the removal of unused V2 streaming snapshot code, and CI changes that pause idle source-build jobs now that Spark 4.0 to 4.3 use published artifacts. The last user-facing fix in the window is still 3.3.3's log cleanup correction.
◆ Where it's heading
The 4.5 line is being prepared in the open through kernel builds and cleanup, with the Spark connector consolidating V2 streaming onto the V1 snapshot path. The feed shows no 4.5 release notes yet.
◆ Prediction
A 4.5.0 release candidate or tag is the next visible step; until then expect more kernel builds and cleanup PRs.
OpenMetadata
5.0ANALYTICS
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.
