Arcade DB

We ran 34 distributed-correctness tests on ArcadeDB's HA layer using the open-source Jepsen framework. All 34 passed. Caveat first: this is NOT an official Jepsen LLC analysis. It is our own use of the tooling on our own database. Repo & methodology in thread.

🚀 ArcadeDB 26.5.1 is out! + Sparse Vector Index (BM25/SPLADE) + Server-side Hybrid Retrieval (RRF, DBSF, LINEAR) + INT8 quantization end-to-end + EXTERNAL property storage + Query partitioning 270+ commits, 128 issues closed arcadedb.com/blog/arcadedb-…

If you find a real linearizability violation, a lost write, or an isolation anomaly we missed, please open an issue: github.com/ArcadeData/arc… PRs adding aggressive nemeses, longer durations, or tighter checkers are very welcome.

Why publish this? Most graph databases (@Neo4j, @ArangoDB, @FalkorDB, Kuzu) have never published distributed correctness work. The default is "trust the marketing page." We wanted to put up or shut up. The repo is the receipts.

Query Profiler is now a first-class feature across HTTP, Studio, embedded, and drivers. Beyond planner and executor timings, it also accounts for record deserialization and result serialization, so you see where time is actually spent.

ArcadeDB 26.4.2 is out! 340+ commits. 100+ issues closed. Headliners: - Raft-based HA on Apache Ratis - End-to-end Query Profiler - Major OpenCypher correctness round - Bolt + TLS - Case-insensitive indexes (COLLATE) Release: github.com/ArcadeData/arc… Thread below.
