Apache Iceberg vs OpenHouse
A side-by-side editorial comparison of Apache Iceberg and OpenHouse — release velocity, themes, recent moves, and the top alternatives to consider.
Apache Iceberg vs OpenHouse: at a glance
What is Apache Iceberg?
Iceberg's release cadence is now backports and CVE patches across three live minor lines.
The project is maintaining 1.9.x, 1.10.x and 1.11.x concurrently, and the visible work is overwhelmingly maintenance: dependency bumps, backported fixes, and a steady stream of correctness repairs around nullability, deletes and the REST catalog. 1.10.2 in particular is almost entirely backports plus a CVE fix in a compression dependency.
What is OpenHouse?
OpenHouse locks down its column-defaults capability flag as default values near completion.
OpenHouse shipped eleven builds (v0.5.529 to v0.5.539) in a week. The substantive work is a pluggable pre-commit check framework inside doCommit, built so column-default rules run on every commit path, and the first wiring of OpenHouseCatalog to the Views service. v0.5.539 makes the required-capability.column-defaults property immutable, and earlier builds added a tableExists endpoint, opt-in Spark SQL ALTER TABLE ... UNLOCK, and validation that blocks RTAS combined with WAP or replication.
Apache Iceberg vs OpenHouse: editorial side-by-side
Apache Iceberg
0.0ANALYTICS
Iceberg's release cadence is now backports and CVE patches across three live minor lines.
◆ Current state
The project is maintaining 1.9.x, 1.10.x and 1.11.x concurrently, and the visible work is overwhelmingly maintenance: dependency bumps, backported fixes, and a steady stream of correctness repairs around nullability, deletes and the REST catalog. 1.10.2 in particular is almost entirely backports plus a CVE fix in a compression dependency.
◆ Where it's heading
The feature story lives in the minor releases and the spec, not the patches — Flink 2.0 support, Variant type work reaching Parquet readers, and repeated REST catalog validation fixes point at a format spending its effort on engine breadth and on the REST catalog as the standard access path. The patch stream shows a format mature enough that its hardest problems are now schema-evolution edge cases and cleanup-on-failure semantics.
◆ Prediction
Expect continued parallel maintenance of the 1.10.x and 1.11.x lines with backports dominating, and the next substantive work to land in Variant type coverage and REST catalog behaviour rather than in the core table spec.
OpenHouse
5.0ANALYTICS
OpenHouse locks down its column-defaults capability flag as default values near completion.
◆ Current state
OpenHouse shipped eleven builds (v0.5.529 to v0.5.539) in a week. The substantive work is a pluggable pre-commit check framework inside doCommit, built so column-default rules run on every commit path, and the first wiring of OpenHouseCatalog to the Views service. v0.5.539 makes the required-capability.column-defaults property immutable, and earlier builds added a tableExists endpoint, opt-in Spark SQL ALTER TABLE ... UNLOCK, and validation that blocks RTAS combined with WAP or replication.
◆ Where it's heading
LinkedIn's table catalog is moving business rules into the commit itself, so defaults, property rules and commit policies all reject the same way with clear 400s. Views and column default values are being built in parallel, and both are now past plumbing into user-facing guards. The team favors small, reversible steps.
◆ Prediction
Expect column default values and the Views client API to become usable end to end within the next few builds, with more PreCommitCheck rules registered by the tables service.
