Neo4j treibt mit GraphRAG, Vektor-Indizes & Agentic RAG die #KI-Entwicklung voran. Ob #LangChain, #LlamaIndex, #SpringAI oder #VertexAI – das neue Python-Paket und das Model Context Protocol (MCP) verknüpfen Graphdaten nahtlos mit #LLM-Anwendungen.

If you are curious about the inner workings of #cassandra, #debezium, #druid, #elasticsearch, #lucene, #kafka, #neo4j, or #spark then check out https://glennengstrand.info/software/opensource/analysis which presents a static code analysis of these eight open source giants.

Neo4j. Графовая СУБД для RAG и не только

Графовые СУБД, пожалуй, одни из самых специализированных хранилищ, существующих на корпоративном рынке. Neo4j при этом яркий представитель этой категории. C Neo4j я познакомился ещё в далеком 2018-м году, в рамках задачи создания более приятной системы корпоративных знаний чем классические Wiki (некий такой корпоративный Obsidian), ну или основные его части. Это сейчас вы можете радоваться всем благам цивилизации, а в то далёкое время нам надо было очень внимательно относиться к структуре корпоративной базы знаний, т.к. даже поисковые алгоритмы часто оставляли желатель лучшего. Никакого вам ранжирования статей в выдаче по просмотрам и времени создания. Но вцелом с точки зрения базы знаний даже текущие варианты Wiki с ранжированием статей, отображением связанных, последних просмотренных, которые смотрят вместе и т.п. всё равно не решает вопрос оперативного поиска информации. А вот граф - уже другая история. Использовали Obsidian? Понравилось представление информации связаннх заметок? Особенно если качественно проставлять связи. Собсвтенно именно таким образом мы обычно и оперируем информацией. Табличная модель конечно удобна, но несколько более синтетическая история, которую придумали чтобы упростить себе жизнь, потому как оперировать графами технически всё-таки более сложная история.

#neo4j subquery might make it easier to get something working - but in this case it was dog slow compared to rewriting without subquery

https://alanbuxton.wordpress.com/2025/03/30/fun-with-neo4j-subqueries/

Awhile back, I created a web app to find concerts pof bands featured on #BagelRadio . I found it amazingly useful. I am not thinking that I would love to have something like this for other concerts.

I am thinking of creating a general-purpose database for events and different views of the data for different interests. One that comes to mind is artists featured here on Six Degrees of Ohio.

This would also allow me to play with a #GraphDatabase like #Neo4J while i am at it.

So, I've been learning #GraphDatabases with #Neo4j this week. I think it would be SUPER fun to recursivlely do an mheard on all the #PacketRadio nodes, to help establish paths around the country.

Weeknote 12/2025: In which spring arrives, I learn about neo4j and I reacquaint myself with the sims after 20 years. #neo4j #personal #weeknotes #graphdb #TheSims https://brainsteam.co.uk/2025/3/23/weeknote-12/

My friend @myfear wrote a really nice blog post about #Quarkus #Neo4j and the power of #relationships for intelligent applications:

Thank you Markus!!

Today I created a #Flyway plugin for #neo4j using our #JDBC driver

https://github.com/michael-simons/neo4j-flyway-database

But Michael, aren't you the main author of Neo4j-Migrations?

I sure am and both the latter and the new plugin create the same meta-graph for the migrations and are mostly compatible.

#FreeSoftwareFoundation rides to defend #AGPLv3 against #Neo4j license add-ons
FOSS bods file amicus brief in hope of preserving core #GNU tenet of freedom forever
"At stake is the future of not just the AGPLv3, but the #FSF's widely used GNU Public License it is largely based on, and the software covered by those agreements."
https://www.theregister.com/2025/03/04/free_software_foundation_agplv3/ #GPL #GPLv3

Talk me out of building a #Neo4j implementation in parallel to my existing #PostgreSQL DB (with a subset of tables as nodes) for queries that tend to be "graph-like" in nature.

In particular, I'm thinking of failure analysis, predictive maintenance, etc in relation to physical infrastructure I model as a directed acyclic graph.

Is this just my #ADHD wanting to try something new, or could I actually find value in this side-quest?

#Klarna: "Yes, we did shut down #Salesforce a year ago, as we have many #SaaS providers."

After previously pushing #Neo4j to correct their abuse of the #AGPL our sister organisation the @fsf now submitted an amicus brief to defend #softwarefreedom . The #GNU licenses were designed to empower users and it is important that we as #FreeSoftware community make sure this is understood.

https://www.fsf.org/news/fsf-submits-amicus-brief-in-neo4j-v-suhy

We submitted an amicus brief in the case entitled #Neo4j, Inc., et al. v. Suhy, et al., Case No. 24-5538 in the Court of Appeals for the Ninth Circuit. Read the details here: https://www.fsf.org/news/fsf-submits-amicus-brief-in-neo4j-v-suhy

Adverse appeals court ruling could kill GPL software license
—@theregister

｢ In May 2018, Neo4j dropped the GNU Affero General Public License (AGPL) for its Neo4j EE (enterprise edition) and replaced it with a new license that incorporated the AGPLv3 with the Commons Clause license. The revised license disallowed non-paying software users from reselling the code or offering support services ｣

https://www.theregister.com/2025/02/27/adverse_appeals_court_ruling_could/

#Appealscourt may kill a #GNU #GPL software license
If #appellatecourt upholds Neo4j v. PureThink decision, which endorsed database maker #Neo4j's right to amend GNU Affero General Public License, version 3 (#AGPL), governing use of its software with new binding terms, current assumptions about enforceability of #copyleft licenses will no longer apply. Issue before appeals court boils down to the right to remove contractual restrictions added to the terms of the #APGLv3.
