Grafana Mimir vs OpenHouse

Grafana Mimir vs OpenHouse: at a glance
What is Grafana Mimir?
Mimir's feed is weekly chart bot noise; the 3.2 RC is where the breaking changes hide.
Almost every entry in this window is an identical bot-generated Helm chart release — byte-for-byte the same body across seven tags. The one substantive release is the 3.2.0 RC, whose notes run past the feed's truncation point: continued Mimir Query Engine optimisation, native histogram support in more operators, per-tenant cost attribution trackers, and a tenant-fair compute worker pool on the ingester. Buried in its changelog are changes operators must act on — the embedded per-tenant Alertmanager web UI is gone, credential-bearing headers are now rejected at startup, and querier/store-gateway traffic requires coming from 3.1.
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).

Grafana Mimir
5.0ANALYTICS
Mimir's feed is weekly chart bot noise; the 3.2 RC is where the breaking changes hide.
◆ Current state
Almost every entry in this window is an identical bot-generated Helm chart release — byte-for-byte the same body across seven tags. The one substantive release is the 3.2.0 RC, whose notes run past the feed's truncation point: continued Mimir Query Engine optimisation, native histogram support in more operators, per-tenant cost attribution trackers, and a tenant-fair compute worker pool on the ingester. Buried in its changelog are changes operators must act on — the embedded per-tenant Alertmanager web UI is gone, credential-bearing headers are now rejected at startup, and querier/store-gateway traffic requires coming from 3.1.
◆ Where it's heading
Mimir is deepening the query path rather than widening the product: most of 3.2 is MQE work, subquery spin-off, caching and elimination passes, largely behind experimental flags. The operational surface is growing in parallel — Kafka producer controls, mimirtool and kafkatool subcommands, SigV4 for shared API clients. The chart is versioned and released independently on a weekly bot cadence, which is why the feed reads as empty even in an active month.
◆ Prediction
The experimental MQE flags that landed in 3.2 are the ones to watch for promotion to default in 3.3, particularly subquery spin-off and scalar common subexpression elimination. Whether a 3.2.0 final follows this RC is not visible in the feed — only the RC has been published here.

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.
