What is Grafana Mimir?

Mimir's feed is mostly Helm automation; the real work is inside the query engine.

The apparent cadence is misleading — five of the last seven entries are bot-generated weekly Helm chart releases carrying no functional change. The substantive item is the 3.2 release candidate, which collects 693 PRs from 61 authors and concentrates on Mimir Query Engine optimizations, PromQL function coverage, and native histogram handling.

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.

Grafana Mimir vs OpenHouse: editorial side-by-side

5.0

Mimir's feed is mostly Helm automation; the real work is inside the query engine.

◆ Current state

The apparent cadence is misleading — five of the last seven entries are bot-generated weekly Helm chart releases carrying no functional change. The substantive item is the 3.2 release candidate, which collects 693 PRs from 61 authors and concentrates on Mimir Query Engine optimizations, PromQL function coverage, and native histogram handling.

◆ Where it's heading

MQE is where the engineering is going: added support for histogram_quantiles, a native histogram trim operation, and a rename of the experimental duration-arithmetic helpers to min_of and max_of. The chart pipeline runs on its own weekly schedule and says nothing about product direction, so read this feed by ignoring roughly two-thirds of it.

◆ Prediction

With 3.2.0-rc.0 out, a 3.2.0 general release is the near-certain next step, followed by a mimir-distributed chart release once the weekly train picks up the new version.

5.0

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.
