Last week, the Kùzu Inc team announced that they will no longer actively support the open-source KuzuDB project. I've been a fan of KuzuDB and think its discontinuation leaves a big gap in the graph ecosystem. This is especially the case for open-source solutions – over the last few years, many open-source graph database systems were forked, relicensed or discontinued. Currently, users looking for an OSS graph database are left to pick from: - community editions of systems with enterprise/cloud offerings (Neo4j, Dgraph) - variants of a heavily-forked system (ArcadeDB / YouTrackDB, HugeGraph) - projects under non-OSI approved licenses - experimental systems (e.g., DuckPGQ) I'm wondering whether this trends continues or someone steps up to maintain KuzuDB or create a new OSS system.

For years, I considered graph databases “interesting but niche.” Relevant commercially for social networks, supply chain and academically for biotech, maybe some knowledge management. Basically, not something most companies would ever need. I stand corrected. With AI, they’re having a very big moment! Working with graphs the first time feels unusual but also just right. The best analogy I have is that feeling we get when we try to visualize a higher dimension when all we have ever known are three (+ time for the purists). (or is it just me?) Two use-cases that I have been riffing on: * Knowledge management: For me it started as a personal project for personal knowledge management. For enterprises, this is where RAG shines. But I also wonder if there are other applications within Enterprise Knowledge Management that we aren’t thinking of yet.  * Master Data Management (MDM): Potentially a subset of above, but explicitly about attributes and relationships that columnar databases might handle too rigidly. I am a lifetime subscriber for relational and SQL till they exist. Not saying they will go away. Graphs still feel intuitive and unusual at the same time. They are still complex to build (although companies like Neo4j simplify them really well), and difficult to traverse / interpret. I believe there is a stronger convergence of these 2 systems coming. Graphs will augment relational before replacing in some of these use-cases. But they have to be way more simplified first for greater adoption. Would love to hear more from graph experts and/or from those who share this feeling of “just right” for graphs. Are you seeing use-cases where graph databases are picking up? #AI #DataStrategy #Graphs #KnowledgeManagement #MDM | 37 comments on LinkedIn

Let's chat a bit about the use of graph databases in retrieval-augmented generation (RAG). One problem in GenAI is that while the LLMs are fed a lot of text during training, perhaps a model isn't fed the specific information the user is asking about, which could be in a private corporate document. Since the dawn of GenAI, pipelines have existed to store private documents in a vector database and search for text relevant to the user's question in the database. This text is then fed to the LLM for use in generating the answer to the user query. One problem in such pipelines is that the document search may retrieve a lot of text containing terms similar to those in the user query which still isn't relevant to answering the query. At this point, many folks say, "knowledge graphs to the rescue!" Knowledge graphs after all can store information about entities mentioned in private documents, so can't they help disambiguate user questions? Graph DBs have been used in RAG for some time now; I started with them in 2021, before ChatGPT existed. There are various problems with using graph data in RAG. First off, the knowledge graphs we are trying to leverage are themselves generated by machine learning. But what are the guarantees that ML engineers are training their models or agents to produce useful KGs? Are we even using the right kind of statistical learning, never mind agent architectures? After all, if you are going to build a KG based on information in natural language, then you are parsing out conceptual relations from natural language, which are dependent on syntax. So perhaps we should be utilizing machine learning in the syntactic parsing problem, so that we ensure a relation isn't added to the graph if the syntax expresses the negation of the relation, for instance. To graph data modelers, again I maintain that methods for extracting information from syntax have more bearing on the use of graph data in RAG than existing modeling techniques that fail to factor in natural language syntax just like most ML inference fails here. And perhaps graph databases aren't even the right target for storing extracted conceptual relations; I switched to logic databases after a month of working with graphs. The use of KGs and logic bases in RAG needs to be tackled through innovations in syntax parsing like semantic grammars, and through better techniques for performant inference engines than graph query, such as GPU-native parallel inference engines. This isn't a problem I expect to be solved through Kaggle competitions or corporate R&D leveraging recently minted ML engineers.

I am excited to announce the formation of a Data Façades W3C Community Group. Façade-X, initially introduced at SEMANTICS 2021 and successfully implemented by the SPARQL Anything project, provides a simple yet powerful, homogeneous view over diverse and heterogeneous data sources (e.g., CSV, JSON, XML, and many others). With the recent v1.0.0 release of SPARQL Anything, the time was right to work on the long-term stability and widespread adoption of this approach by developing an open, vendor-neutral technology. The Façade-X concept was born to allow SPARQL users to query data in any structured format in plain SPARQL. Therefore, the choice of a W3C community group to lead efforts on specifications is just natural. Specifications will enhance its reliability, foster innovation, and encourage various vendors and projects—including graph database developers — to provide their own compatible implementations. The primary goals of the Data Façades Community Group is to: Define the core specification of the Façade-X method. Define Standard Mappings: Formalize the required mappings and profiles for connecting Façade-X to common data formats. Define the specification of the query dialect: Provide a reference for the SPARQL dialect, configuration conventions (like SERVICE IRIs), and the functions/magic properties used. Establish Governance: Create a monitored, robust process for adding support for new data formats. Foster Collaboration: Build connections with relevant W3C groups (e.g., RDF & SPARQL, Data Shapes) and encourage involvement from developers, businesses, and adopters. Join us!

It's great to see the launch of Google Cloud's new Agentspace Knowledge Graph, built on Spanner Graph. Agentspace Knowledge Graph (https://lnkd.in/gYM6xZQS) allows an AI agent to understand the real-world context of your organization—the web of relationships between people, projects, and products. This is the difference between finding a document and understanding who wrote it, what team they're on, and what project it's for. Because this context is a network, the problem is uniquely suited for a graph model. Spanner Graph (https://lnkd.in/gkwbGFbS) provides a natural way to model this reality, allowing an AI agent to instantly traverse complex connections to find not just data, but genuine insight. This is how we move from AI that finds information to AI that understands it. The ability to reason over the "why" behind the data is a true game-changer. #GoogleCloud #GenAI #Agentspace #SpannerGraph #KnowledgeGraph

𝗖𝗮𝗻 𝗮 𝗥𝗲𝗹𝗮𝘁𝗶𝗼𝗻𝗮𝗹 𝗗𝗮𝘁𝗮𝗯𝗮𝘀𝗲 𝗕𝗲 𝗮 𝗞𝗻𝗼𝘄𝗹𝗲𝗱𝗴𝗲 𝗚𝗿𝗮𝗽𝗵? Not all knowledge graphs are equal. A semantic KG (RDF/OWL/Stardog) isn’t the same as a property graph (Neo4j), and both differ from enforcing graph-like structures in a relational DB (CockroachDB/Postgres). Each has strengths and trade-offs: 𝗦𝗲𝗺𝗮𝗻𝘁𝗶𝗰 𝗞𝗚𝘀 excel at reasoning and inference over ontologies. 𝗣𝗿𝗼𝗽𝗲𝗿𝘁𝘆 𝗴𝗿𝗮𝗽𝗵𝘀 shine when exploring relationships with intuitive query patterns. 𝗥𝗲𝗹𝗮𝘁𝗶𝗼𝗻𝗮𝗹 𝗮𝗽𝗽𝗿𝗼𝗮𝗰𝗵𝗲𝘀 enforce graph-like models via schema, FKs, indexes, recursive CTEs — with added benefits of scale, distributed TXs, and decades of maturity. 𝗚𝗿𝗮𝗽𝗵 𝗧𝗿𝗮𝘃𝗲𝗿𝘀𝗮𝗹𝘀 𝗶𝗻 𝗦𝗤𝗟 Recursive CTEs let SQL “walk the graph.” Start with a base case (movie + actors), then repeatedly join back to discover multi-hop paths (actors → movies → actors → movies). This simulates “friends-of-friends” traversals in a few lines of SQL. 𝗥𝗔𝗚, 𝗚𝗿𝗮𝗽𝗵𝗥𝗔𝗚, 𝗮𝗻𝗱 𝗟𝗟𝗠𝘀 RAG and GraphRAG give LLMs grounding in structured data, reducing hallucinations and injecting context. Whether via RDF triples, LPG edges, or SQL joins — the principle is the same: real relationships fuel better answers. 𝗧𝗵𝗲 𝟯-𝗛𝗼𝗽 𝗔𝗿𝗴𝘂𝗺𝗲𝗻𝘁 Some vendors claim SQL breaks down after 3 hops. In reality, recursive CTEs traverse arbitrary depth. SQL may not be as compact as Cypher or GQL, but it’s expressive and efficient — the “3-hop wall” is outdated FUD. 𝗟𝗼𝗮𝗱𝗶𝗻𝗴 𝗗𝗮𝘁𝗮 𝗮𝘁 𝗦𝗰𝗮𝗹𝗲 One graph DB is notorious for slow, resource-heavy CSV loads. Distributed RDBMS like CockroachDB can bulk ingest 100s of GB to TBs efficiently. 𝗡𝗼 𝗦𝘁𝗮𝗹𝗲 𝗗𝗮𝘁𝗮 Too often, data must move from TX systems into a graph before use — by then, it’s stale. For AI-driven apps, that lag means hallucinations, missed insights, and poor UX. 𝗪𝗵𝘆 𝗧𝗵𝗶𝘀 𝗠𝗮𝘁𝘁𝗲𝗿𝘀 𝗳𝗼𝗿 𝗔𝗜 As AI apps go multi-regional and global, they demand low latency + strong consistency. Centralized graph DBs hit lag, hotspots, scaling pain. Distributed SQL delivers expressive queries and global consistency — exactly what AI workloads need. You don’t need to pick “graph” or “relational” as religion. Choose the right model for scale, consistency, and AI grounding. Sometimes RDF. Sometimes LPG. And sometimes, graph-enforced in SQL. #KnowledgeGraph #ArtificialIntelligence #GenerativeAI #DistributedSQL #CockroachDB | 11 comments on LinkedIn
