OpenHouse vs OR-Tools
A side-by-side editorial comparison of OpenHouse and OR-Tools — release velocity, themes, recent moves, and the top alternatives to consider.
OpenHouse vs OR-Tools: at a glance
What is OpenHouse?
LinkedIn's Iceberg control plane, shipping one pull request per release.
OpenHouse is LinkedIn's open-source control plane for Iceberg tables, and it releases per merged pull request — version numbers climb several times a week with a single change each. The current work is concentrated on making the service defensible in production: a fix for CREATE OR REPLACE AS SELECT silently wiping table policies, request-ID correlation and a typed exception hierarchy in the data loader, and targeted scheduler logging for jobs observability.
What is OR-Tools?
Google's solver suite where nearly every release note is really about CP-SAT.
OR-Tools bundles constraint programming, linear solvers, routing, and graph algorithms, but the release notes make the priority obvious: CP-SAT gets the most substantive changes in every version, particularly its no_overlap_2d propagation, presolve, and cut management. Around that core, the work is platform and dependency maintenance — new Linux distro support, Python and Java version cycling, and bumping the bundled Coin-OR, HiGHS, SCIP, and abseil versions. Note that these entries carry batch-stamped crawl dates; the newest actual release here is v9.12 from early 2025.

OpenHouse
5.0ANALYTICS
LinkedIn's Iceberg control plane, shipping one pull request per release.
◆ Current state
OpenHouse is LinkedIn's open-source control plane for Iceberg tables, and it releases per merged pull request — version numbers climb several times a week with a single change each. The current work is concentrated on making the service defensible in production: a fix for CREATE OR REPLACE AS SELECT silently wiping table policies, request-ID correlation and a typed exception hierarchy in the data loader, and targeted scheduler logging for jobs observability.
◆ Where it's heading
The theme across these releases is treating table metadata as something that must not be lost by accident, and making failures attributable. Policies now merge rather than being rebuilt from the request. Data loader errors carry a request ID and distinguish authentication from transport failure instead of retrying auth errors as transient. Feature toggles gained self-service table overrides so server-side ramps and table-owner opt-in can coexist.
◆ Prediction
The jobs-observability plan explicitly defers OTEL gauges, a heartbeat sampler, and DLQ counters to a later phase, so those are the concrete next steps visible in these entries.
OR-Tools
0.0ANALYTICS
Google's solver suite where nearly every release note is really about CP-SAT.
◆ Current state
OR-Tools bundles constraint programming, linear solvers, routing, and graph algorithms, but the release notes make the priority obvious: CP-SAT gets the most substantive changes in every version, particularly its no_overlap_2d propagation, presolve, and cut management.

Note that these entries carry batch-stamped crawl dates; the newest actual release here is v9.12 from early 2025.
◆ Where it's heading
The suite is consolidating on fewer, better-maintained components: old graph classes were removed outright, MathOpt got a deep rework and shipped in the Python wheel, and the Python API was rewritten to PEP 8 naming. Build-level changes point the same direction — dependencies split into separate shared libraries, Windows output moved to DLLs.
◆ Prediction
CP-SAT scheduling and 2D packing propagation should keep absorbing the bulk of the effort; the entries show no other component receiving comparable sustained investment.
