What is Apache Baremaps?

Baremaps got geoparquet and hillshading, then went quiet for eighteen months in incubation

Apache Baremaps is a pipeline for building vector map tiles from OpenStreetMap and raster sources, still carrying the incubating designation across every release in this window. The work splits between format support and the tile-serving path: geoparquet reading arrived in 0.8.1 along with vector contours and hillshades generated from raster tiles, while 0.8.2 fixed a Postgres tile store performance issue and added a materialized-views refresher. Release notes open with the same appeal for new contributors every time, which is itself a signal about the size of the community.

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.

Apache Baremaps vs OpenHouse: editorial side-by-side

A0.0

Baremaps got geoparquet and hillshading, then went quiet for eighteen months in incubation

◆ Current state

Apache Baremaps is a pipeline for building vector map tiles from OpenStreetMap and raster sources, still carrying the incubating designation across every release in this window. The work splits between format support and the tile-serving path: geoparquet reading arrived in 0.8.1 along with vector contours and hillshades generated from raster tiles, while 0.8.2 fixed a Postgres tile store performance issue and added a materialized-views refresher. Release notes open with the same appeal for new contributors every time, which is itself a signal about the size of the community.

◆ Where it's heading

Two threads are visible. One is broadening what Baremaps can read and produce — geoparquet in, terrain-derived vector layers out — which pushes it past OSM-to-tiles toward a general geospatial pipeline. The other is making the Postgres-backed tile store hold up under load, with version-dependent query generation and materialized view refreshing suggesting real deployments hit its limits. Cadence has been slowing throughout: roughly nine months between 0.7.1 and 0.7.2, eleven to 0.8.1, then two months to 0.8.2, and nothing published since February 2025.

◆ Prediction

The entries offer no roadmap statement, and eighteen months without a release makes the incubation status the open question rather than the feature set; nothing here indicates whether graduation or dormancy is the more likely next step.

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.
