Citus vs OpenHouse
A side-by-side editorial comparison of Citus and OpenHouse — release velocity, themes, recent moves, and the top alternatives to consider.
Citus vs OpenHouse: at a glance
What is Citus?
Citus is in maintenance mode across four branches, with the feature work invisible from the feed.
Citus is the Postgres extension that shards tables across a cluster, and its release feed right now is almost entirely branch upkeep. Four lines are live at once — 12.1, 13.3, 14.0 and 14.1 — and the recent tags are backports and CI fixes moving between them, authored by a small handful of maintainers. The last release with user-facing feature text is Citus 14.0 in February, which added PostgreSQL 18.1 support and pointed at a blog post rather than listing what changed.
What is OpenHouse?
OpenHouse breaks ground on Iceberg views while tightening storage lifecycle and authorization
OpenHouse (LinkedIn's managed Iceberg tables service) is shipping at a rapid v0.5.x pace with multiple improvements per week. Recent work spans three areas: storage lifecycle management (native snapshot expiration with reference age defaults, orphan file reclamation), authorization hardening (routing RTAS operations through proper table privilege checks), and the first scaffolding for Iceberg view support (entityType discriminator, table-scoped HTS queries).

Citus is in maintenance mode across four branches, with the feature work invisible from the feed.
◆ Current state
Citus is the Postgres extension that shards tables across a cluster, and its release feed right now is almost entirely branch upkeep. Four lines are live at once — 12.1, 13.3, 14.0 and 14.1 — and the recent tags are backports and CI fixes moving between them, authored by a small handful of maintainers. The last release with user-facing feature text is Citus 14.0 in February, which added PostgreSQL 18.1 support and pointed at a blog post rather than listing what changed.
◆ Where it's heading
The shape here is a mature extension keeping several supported branches alive rather than pushing new capability. Correctness is the live concern: the 12.1 patches fix wrong query results, an EXPLAIN segfault, a standby coordinator crash and a deadlock, all backported from work done on newer branches. Note that the release notes are thin by design — 13.3 and 14.1 list only PR titles for backports and test plumbing, so the feed understates whatever is landing on the main line.
◆ Prediction
More 12.1 patch tags are the safe expectation while that branch stays supported. Whether the 14.x line picks up new distributed-query features is not visible from these entries — the notes only cover backports, so the main-branch work would have to be read elsewhere.

OpenHouse breaks ground on Iceberg views while tightening storage lifecycle and authorization
◆ Current state
OpenHouse (LinkedIn's managed Iceberg tables service) is shipping at a rapid v0.5.x pace with multiple improvements per week. Recent work spans three areas: storage lifecycle management (native snapshot expiration with reference age defaults, orphan file reclamation), authorization hardening (routing RTAS operations through proper table privilege checks), and the first scaffolding for Iceberg view support (entityType discriminator, table-scoped HTS queries).
◆ Where it's heading
The entityType discriminator in v0.5.490 is the most directional move in this window — it creates the data model prerequisite for treating views as first-class entities alongside tables, something OpenHouse has not supported. Storage lifecycle work is converging on Iceberg-native mechanisms, reducing custom expiration logic. The post-commit operations framework in v0.5.492 is infrastructure that will allow OpenHouse to add downstream hooks (compaction triggers, notifications) without catalog coupling.
◆ Prediction
Iceberg view read support will arrive in the next several releases, building on the discriminator and HTS scaffolding now in place. The authorization model for views will be an open question — watch whether they reuse the table ACL path or introduce a parallel model.
