🚀 Announcing ArcadeDB 26.5.1

We've just shipped a major release: 270+ commits and 128 issues resolved. The headline is hybrid retrieval, but there's a lot more inside.

What's new:

• Sparse Vector Index (LSM_SPARSE_VECTOR) for BM25 / SPLADE-style retrieval, with WAND and BlockMax-WAND pruning that scales to 100M+ documents
• Server-side Hybrid Retrieval via vector.fuse(...) (RRF, DBSF, LINEAR strategies) — combine dense, sparse, and lexical signals without client round-trips
• INT8 quantization end-to-end across ingest, storage, and query (dramatically lower disk and RSS)
• EXTERNAL property storage: a paired-bucket layout that isolates heavy values (vectors, large JSON, blobs) so scans stay hot
• Query partitioning with a partition-aware planner that prunes unnecessary partitions
• Offline HA cluster bootstrap via snapshot-and-restore (no full re-replication)
• Production-ready Helm chart, aligned with the Raft-based HA subsystem
• Extensive OpenCypher correctness improvements
• FIND REFERENCES is back, easing OrientDB migrations

100% backward compatible. No export/import needed when upgrading.

ArcadeDB 26.4.2 is here.

This release packs 340+ commits and 100+ resolved issues into one of our biggest updates yet.

What's new:

A brand-new Raft-based High Availability stack built on Apache Ratis. Leader election and log replication are now handled by a battle-tested consensus implementation, giving you stronger guarantees for replicated writes and cleaner operations on Kubernetes and bare metal.

The Query Profiler is now available across every entrypoint (HTTP, Studio, embedded, drivers) and shows the full time breakdown, including record deserialization and result serialization.

A massive OpenCypher correctness round with dozens of fixes: filter pushdown for list predicates, dynamic index usage for MATCH WHERE ID(n), CREATE INDEX and CREATE CONSTRAINT IS TYPED support, WALK / TRAIL / ACYCLIC path modes, and many subquery fixes.

Plus: Bolt wire protocol with TLS, batch SQL UPDATE / DELETE / TRUNCATE, case-insensitive COLLATE indexes, production-mode auto-fsync with a startup security checklist, Studio polish (horizontal scroll, progress bars, clickable datasets), and major performance gains including an 80%+ RAM drop on the Neo4j importer.

got archived after the Apple acquisition. If you're looking for a migration path, we wrote a practical guide to move from Kuzu to ArcadeDB - covering schema translation, data import, and query
migration (most Cypher queries work unchanged).

A practical migration guide from KuzuDB to ArcadeDB for multi-model graph workloads. Honest comparison, step-by-step data migration, and schema mapping reference.
