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 Neo4j?

Neo4j's Virtual Graph lets you run Cypher against Snowflake and BigQuery without moving any data.

Neo4j is expanding Aura's geographic reach (AWS London and Montreal this week) while pushing two substantial capability betas: Virtual Graph — a zero-copy bridge that translates Cypher to SQL against BigQuery, Databricks, and Snowflake — and Multiple Databases in a single instance. The August release also shipped native UUID types in Cypher 25 and ABAC for fine-grained access control.

Apache Storm vs Neo4j: editorial side-by-side

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.

Neo4j's Virtual Graph lets you run Cypher against Snowflake and BigQuery without moving any data.

◆ Current state

Neo4j is expanding Aura's geographic reach (AWS London and Montreal this week) while pushing two substantial capability betas: Virtual Graph — a zero-copy bridge that translates Cypher to SQL against BigQuery, Databricks, and Snowflake — and Multiple Databases in a single instance. The August release also shipped native UUID types in Cypher 25 and ABAC for fine-grained access control.

◆ Where it's heading

Neo4j is positioning itself as the graph layer on top of existing data warehouses rather than a replacement for them. Virtual Graph and ABAC together signal a push into enterprise data architectures where teams have data in Snowflake or BigQuery and want graph traversal without ETL. The multiple-databases GA (coming in months per the release) reinforces that Aura is targeting organizations running multiple isolated tenants on a single cluster.

◆ Prediction

Virtual Graph will likely exit preview with paid pricing attached once the query-pushdown behavior stabilizes; the next move is probably native support for LLM embedding pipelines that stay in Aura without exporting data to a warehouse.
