Delta Lake vs OpenHouse
A side-by-side editorial comparison of Delta Lake and OpenHouse — release velocity, themes, recent moves, and the top alternatives to consider.
Delta Lake vs OpenHouse: 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 OpenHouse?
OpenHouse adds time-zone-aware retention and per-database table caps.
OpenHouse ships small versioned releases straight from merged pull requests. On November 13 it shipped five: retention policies on string date columns can now take a time zone, operators can cap live tables per database with metrics on usage and rejections, view requests and operations are now audited in full, and two fixes make view property SET/UNSET and REPLACE behave. Earlier in November failed Spark maintenance jobs began exiting as failed.
Delta Lake vs OpenHouse: editorial side-by-side
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.
OpenHouse
5.0ANALYTICS
OpenHouse adds time-zone-aware retention and per-database table caps.
◆ Current state
OpenHouse ships small versioned releases straight from merged pull requests. On November 13 it shipped five: retention policies on string date columns can now take a time zone, operators can cap live tables per database with metrics on usage and rejections, view requests and operations are now audited in full, and two fixes make view property SET/UNSET and REPLACE behave. Earlier in November failed Spark maintenance jobs began exiting as failed.
◆ Where it's heading
OpenHouse is adding the controls a shared lakehouse needs at scale: quotas, audit trails and retention that matches business calendars. Views are getting the same governance tables already had.
◆ Prediction
Expect more views milestones after audit (the release is labeled Views M1), and further operator controls for quotas and maintenance.
