What is Delta Lake?

Delta Lake's public stream is release mechanics; Kernel builds now carry a 4.5.0 label.

Recent Delta Lake activity is mostly release mechanics: 4.4.0 and 4.4.1 tags, a stream of Databricks runtime kernel builds, and patch releases. The newest build is labelled Delta Kernel 4.5.0, the first sign of the next minor line. The substantive user-facing work sits in patches such as the 3.3.3 fix for log cleanup deleting files still needed for time travel.

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.

Delta Lake vs OpenHouse: editorial side-by-side

D
Delta Lake
ANALYTICS
5.0

Delta Lake's public stream is release mechanics; Kernel builds now carry a 4.5.0 label.

◆ Current state

Recent Delta Lake activity is mostly release mechanics: 4.4.0 and 4.4.1 tags, a stream of Databricks runtime kernel builds, and patch releases. The newest build is labelled Delta Kernel 4.5.0, the first sign of the next minor line. The substantive user-facing work sits in patches such as the 3.3.3 fix for log cleanup deleting files still needed for time travel.

◆ Where it's heading

The project keeps 3.x and 4.x alive and spends its public changelog on correctness and catalog integration rather than new table features. Kernel builds tagged for Databricks runtime suggest Kernel development is paced by Databricks' own release train, with the open-source releases following.

◆ Prediction

A 4.5.0 open-source release is the likely next notable entry given the kernel version label, but the entries don't say what it will contain.

5.0

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.
