ArcadeDB 26.10.2 is out.
• Query admission gate: a busy server queues requests instead of exhausting the heap
• Point lookups 3 to 7x faster
• Native openCypher temporals

What's the best algorithm for the shortest path between two points on a map?
Dijkstra and A*: ~100 ms across 1M Florida junctions.
Contraction Hierarchies: 0.04 ms. Same exact route, and it follows live traffic.
Now in ArcadeDB, Apache 2.0:

ISO GQL now runs in ArcadeDB's Cypher 25 engine: mix GQL and Cypher in the same query, no switch needed.
Path modes, FILTER, INSERT and START TRANSACTION work today.

ALT Our newest offering, Tom Sawyer Digital Engineering 1.0, uses interactive graph and data visualizations to help teams explore system structures, plans, workflows, dependencies, and supply chains.
Kainora gives retrieval more paths to evidence: a knowledge graph in ArcadeDB, next to keyword and vector search, running on Docker and Kubernetes.

ArcadeDB 26.10.1 is out.
1,244 issues resolved, 984 bug fixes (75 critical), ~300 HA/Raft fixes, 4 security advisories patched, 100+ wire protocol improvements (Postgres, MongoDB, Redis, Bolt).
The "make it rock solid" release.

The PostgreSQL community is working on SQL/PGQ: MATCH patterns for graph queries, written in SQL.
Will that make it a graph database? We ran LDBC LSQB (SF1, 3.9M vertices, 17.9M edges) on both.
ArcadeDB: 2.21 s total
PostgreSQL: 69.07 s total
31x gap. Here is why
ArcadeDB is now the graph database backbone of Tom Sawyer Digital Engineering from @tsawyersoftware 🎉
6 modules (Planning, BPMN, SysML v2, Data Streams, Perspectives, Explorations), one graph underneath.
Apache 2.0, no proprietary DB license cost.

A team running RAG over 40M+ legal/medical docs outgrew Neo4j Community: 3.1B nodes, 8B edges, 640M vectors, hand-sharded to avoid the HA license.
Their write-up on moving to ArcadeDB is refreshingly honest, caveats included.

Best advice in the post, whatever database you use: build a ~500-question gold set before you migrate. It turns a religious argument into a table, and becomes your regression suite.
And the line we'll be quoting for a while:
"Licensing is an architecture constraint."
Thanks u/hncvj for sharing. ArcadeDB is Apache 2.0, HA included: arcadedb.com
Apache Arrow reaches ArcadeDB through its PostgreSQL wire protocol. No new driver needed.
A 3-week test by adbcBridge found 4 protocol gaps. The first fix took 4.5 hours, an external PR merged the same day, and every fix went upstream.

ArcadeDB is now a first-class integration in Google's MCP Toolbox for Databases: the open-source MCP server for AI agents. Query graph, document, vector & time-series data in Cypher or SQL from Claude, Cursor, or any MCP client. How + why:

ArcadeDB now has native drivers for Python and TypeScript.
Four packages, two transports (HTTP and gRPC), generated from one OpenAPI spec and one Protobuf file. Apache-2.0, on PyPI and npm today.
pip install arcadedb-driver
npm install @arcadedb/driver

3. The truncated flag
A 5,000-row result that stopped early looks exactly like one that ran out of matches.
That is why the ArcadeDB drivers return the full envelope (result, limit, returned, truncated) instead of a bare array. Check the flag before you trust the rows.
ArcadeDB 26.9.1 is out: 992 issues and pull requests closed over 1,500 commits, the largest release we have ever shipped.
Headline number: a full backup of a 1.25 GB database now takes 0.68s instead of 18.88s.
27.6x faster.

New in ArcadeDB 26.9.1 for clusters:
Optional mTLS on the Raft gRPC transport
Live Raft membership in /api/v1/cluster
A per-protocol HA routing table
Exponential backoff with full jitter on transaction retries
