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 Apache Storm?

Storm 3.0 finishes removing the Clojure it was built in, and moves to a Java 21 baseline.

Storm is running two lines: a 2.8.x maintenance branch that is mostly Dependabot traffic punctuated by real security releases, and the new 3.0.0 line cut on 22 July. 3.0.0 removes all remaining Clojure from the codebase, raises the baseline to Java 21 (with master already on 25), and ships throughput work — zstd compression for thrift cluster state, tuple compression between workers, and decoupling of the control plane from the data plane on receive queues. The 2.8.6 and 2.8.7 releases earlier in the window carried four CVEs, including a deserialization RCE reachable by any user with topology submission rights.

Apache Baremaps vs Apache Storm: 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.

Storm 3.0 finishes removing the Clojure it was built in, and moves to a Java 21 baseline.

◆ Current state

Storm is running two lines: a 2.8.x maintenance branch that is mostly Dependabot traffic punctuated by real security releases, and the new 3.0.0 line cut on 22 July. 3.0.0 removes all remaining Clojure from the codebase, raises the baseline to Java 21 (with master already on 25), and ships throughput work — zstd compression for thrift cluster state, tuple compression between workers, and decoupling of the control plane from the data plane on receive queues. The 2.8.6 and 2.8.7 releases earlier in the window carried four CVEs, including a deserialization RCE reachable by any user with topology submission rights.

◆ Where it's heading

The project is converting itself from a legacy JVM codebase into an ordinary modern Java one, and the 3.0 work shows where that energy goes next: scheduling and queueing. Recent PRs add AIMD dynamic batch sizing to JCQueue, jitter metrics and a jitter-aware stream grouping, round-robin rebalance onto returning supervisors, and several fixes for stale or orphaned worker heartbeats. Alongside that, the distribution is being slimmed — optional Hadoop and Kafka dependencies were unbundled and shared jars de-duplicated. The 2.x branch is being kept alive for security and dependency currency, not for features.

◆ Prediction

Expect 3.0.x point releases to concentrate on the scheduler and worker-lifecycle fixes that 3.0.0 opened up, and expect the 2.8.x line to keep receiving CVE backports while feature work stays on 3.x. The Java 25 baseline already on master suggests the next minor will move the floor again.
