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.

What is Fulcrum?

Fulcrum is consolidating its whole mapping stack on Esri, and retiring Google Maps to finish it.

Fulcrum ships weekly web release notes alongside separate iOS and Android builds, and nearly all of the recent work is mapping. The ArcGIS SDK moved to 300.0.0 on mobile and the map engine picked up current ArcGIS and deck.gl versions on web, while a run of fixes addressed offline layer styling, basemap loading and attachment downloads on poor connections. On-device machine learning inference dropped ONNX for a new format, with labels now read from an uploaded labels.txt file.

Apache Storm vs Fulcrum: editorial side-by-side

A
Apache Storm
ANALYTICS
6.3

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.

6.3

Fulcrum is consolidating its whole mapping stack on Esri, and retiring Google Maps to finish it.

◆ Current state

Fulcrum ships weekly web release notes alongside separate iOS and Android builds, and nearly all of the recent work is mapping. The ArcGIS SDK moved to 300.0.0 on mobile and the map engine picked up current ArcGIS and deck.gl versions on web, while a run of fixes addressed offline layer styling, basemap loading and attachment downloads on poor connections. On-device machine learning inference dropped ONNX for a new format, with labels now read from an uploaded labels.txt file.

◆ Where it's heading

The mapping stack is converging on Esri across every client, and the announced September 1 retirement of the legacy Google Maps engine makes that explicit. Esri Maps has absorbed Google's satellite, hybrid and street basemaps, and the GIS capabilities Fulcrum keeps investing in — snapping, ArcGIS Feature Service connectivity, offline basemaps, GPS tracks, the redesigned location editor — only exist on that engine. Everything else in the feed is stabilization on the same surface, which is what a team does when it is preparing to move every remaining customer onto one path.

◆ Prediction

Expect migration reminders and switching guidance for organizations still defaulting to Google Maps as September 1 approaches, and MMPK layers to leave Early Access once the engine consolidation is complete.
