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 locks down its column-defaults capability flag as default values near completion.
OpenHouse shipped eleven builds (v0.5.529 to v0.5.539) in a week. The substantive work is a pluggable pre-commit check framework inside doCommit, built so column-default rules run on every commit path, and the first wiring of OpenHouseCatalog to the Views service. v0.5.539 makes the required-capability.column-defaults property immutable, and earlier builds added a tableExists endpoint, opt-in Spark SQL ALTER TABLE ... UNLOCK, and validation that blocks RTAS combined with WAP or replication.

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
5.0ANALYTICS
OpenHouse locks down its column-defaults capability flag as default values near completion.
◆ Current state
OpenHouse shipped eleven builds (v0.5.529 to v0.5.539) in a week. The substantive work is a pluggable pre-commit check framework inside doCommit, built so column-default rules run on every commit path, and the first wiring of OpenHouseCatalog to the Views service. v0.5.539 makes the required-capability.column-defaults property immutable, and earlier builds added a tableExists endpoint, opt-in Spark SQL ALTER TABLE ... UNLOCK, and validation that blocks RTAS combined with WAP or replication.
◆ Where it's heading
LinkedIn's table catalog is moving business rules into the commit itself, so defaults, property rules and commit policies all reject the same way with clear 400s. Views and column default values are being built in parallel, and both are now past plumbing into user-facing guards. The team favors small, reversible steps.
◆ Prediction
Expect column default values and the Views client API to become usable end to end within the next few builds, with more PreCommitCheck rules registered by the tables service.
