Cortex vs OpenHouse
A side-by-side editorial comparison of Cortex and OpenHouse — release velocity, themes, recent moves, and the top alternatives to consider.
Cortex vs OpenHouse: at a glance
What is Cortex?
Cortex is betting on Parquet block storage and graduating years of experimental features.
Cortex publishes its release notes as release candidates, and the two majors visible here tell a consistent story. 1.20 introduced Parquet-based block storage, Prometheus Remote Write 2.0, a resource-based limiter for ingesters and store-gateways, and regex tenant resolution, all experimental. 1.21 then made Parquet a Store Gateway query mode, graduated the Ruler API, Alertmanager API and sharding, tenant federation, FIFO/Redis cache and memcached service discovery out of experimental, and enabled the bucket index by default. The 1.21.1 candidate is almost entirely security hardening.
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).

Cortex is betting on Parquet block storage and graduating years of experimental features.
◆ Current state
Cortex publishes its release notes as release candidates, and the two majors visible here tell a consistent story. 1.20 introduced Parquet-based block storage, Prometheus Remote Write 2.0, a resource-based limiter for ingesters and store-gateways, and regex tenant resolution, all experimental. 1.21 then made Parquet a Store Gateway query mode, graduated the Ruler API, Alertmanager API and sharding, tenant federation, FIFO/Redis cache and memcached service discovery out of experimental, and enabled the bucket index by default. The 1.21.1 candidate is almost entirely security hardening.
◆ Where it's heading
Two arcs run in parallel. The storage arc is moving Cortex off pure TSDB blocks toward Parquet, first as a converter and format, then as a queryable Store Gateway mode — the same columnar direction the rest of the observability market has taken for long-retention data. The maturity arc is a deliberate clearing of the experimental backlog, with six subsystems graduating in one release and their flags renamed to drop the experimental prefix. Layered on both is a distinct hardening push: the latest candidate bounds gossip connections, caps decompressed request bodies, adds HMAC stream authentication and validates tenant IDs against the authenticated caller.
◆ Prediction
Expect Parquet to keep progressing from experimental toward default, following the path the bucket index just completed. The security work in 1.21.1 reads like a systematic pass over untrusted input paths rather than a response to a single report, so more of the same in the ingestion and gossip layers is likely.

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.
