ArcadeDB is the company blog at arcadedb.com, writing about data and programming. Since 2022, 5 different Hacker News readers have linked it 21 times, most often “ArcadeDB: Multi-Model Database Supporting Graphs, KV, Documents, TS, and Vectors”. It is still writing: the last post was on 2026-11-02, and you can follow it by feed.
Too few sampled comments (1) to say how often HN recommends it.?
Why HN links it
Only one comment, which recommends JanusGraph with Cassandra or HBase for a social-network graph and does not discuss the ArcadeDB writing. The linked posts cover ArcadeDB, a graph database.
Summarised by Claude from a sample of 1 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
ArcadeDB: open-source multi-model graph database. Native graph, document, key-value, vector, search, and time-series in one ACID-compliant engine.

What Hacker News says?
Why don't just use ArcadeDB ( https://arcadedb.com )? Its Graph OLAP makes graph queries faster than KuzuDB (LadybugDB now).

HN discussionIt would be great if you can add ArcadeDB ( https://arcadedb.com ) in the comparison page. Also, have you done some benchmarks, like the standard LDBC for graph databases? This is a project we keep updated: https://github.com/ArcadeData/ldbc_graphalytics_platforms_ar...

HN discussionCongrats to the SurrealDB team! Shipping 3.0 is a serious milestone. This is also a broader validation moment for the multi-model database space. In a market historically dominated by specialized, single-purpose systems (a separate DB for graphs, another for documents, another for search), it's meaningful that multiple independent projects — SurrealDB, ArcadeDB, and others — are converging on the same thesis: one da…

HN discussionThis resonates strongly. We've been working on exactly this problem with ArcadeDB — a multi-model database that natively supports graphs, documents, key-value, time-series, and vector search in a single engine. ( https://arcadedb.com ) The insight about relationships growing faster than nodes is spot on, and it's why we think the graph model is the natural fit for context layers. But in practice, you also need docum…

HN discussionLadybug is still very limited in terms of use cases and functionalities. Unless you just want some OLAP graph query to be faster, and that's it... You could use a fully functional DBMS with Graph OLAP functionalities, like ArcadeDB (Apache2 license): https://arcadedb.com/blog/graph-olap-engine-the-fastest-grap... . Most importantly, ArcadeDB committed to never change its license, to avoid leaving users left in panic…

HN discussionInteresting project! The single-writer limitation is a real pain point for multi-agent systems. Worth mentioning ArcadeDB ( https://arcadedb.com ) — it's an open-source multi-model database (Apache 2.0) that supports concurrent writes natively, with graph (OpenCypher/Gremlin), document, key-value, and time-series models in one engine. No need to fork or maintain a separate project. It also speaks the Neo4j Bolt prot…

HN discussionA highly capable (open source) graph computing stack would be JanusGraph combined with Apache Cassandra (or Apache HBase). JanusGraph is a TinkerPop provider meaning that the graph can be queried with Gremlin, a powerful graph traversal language combined with a choice of scalable, distibuted backends/persistence stores (as mentioned, Apache Cassandra or Apache HBase). Take a closer look at both the semantic web ecos…
