Off the top of my head, I know of two big and complex pricing engine projects in production. One is the Marriott one I referenced in a previous post. Scott Grimes spoke about it at GraphConnect 2016:…
Indeed, and Neo4j has scaled out horizontally for reads since 2011. However, the really hard problem with scaling graphs is scaling writes, i.e. partitioning. In my mind, no one has solved that well today because you…
Feel free to have a look again and let me know your thoughts. emil@neo4j.com or @emileifrem. 20 of the 25 biggest banks in the world use Neo4j today, and fraud detection (specifically fraud rings) is a really popular…
Oh, there's a bunch of stuff in addition to that. I could give it a shot, but would probably mess it up. :) Way better if you hear it from the horse's mouth. Here's Scott Grimes from Marriott at GraphConnect 2016:…
Hey Mark. Yours was the first ever book on AI that I read back in the 90s so thank you for that. :) I think we're in the early parts of an exciting journey connecting (no pun intended) graphs and AI. I'm personally…
We just did our annual conference GraphConnect in NYC last month. There's a BUNCH of talks online of people who are very successfully and very happily using it in production deployments. Check it out here:…
I hear you. We're working on it. I will note that we have a startup program where you can get Neo4j Enterprise for free if you're below 50 employees and also have several other programs for educational institutions,…
That sucks. :( Sorry about that. Neo4j isn't perfect today and it certainly wasn't perfect 4-5 years ago. We're working hard on it tho! And thanks for being specific (amazed that you remember specific issues from five…
I'm curious, what is lacking from Neo4j to qualify it as a mature graph database? We've worked on it for over a decade, it's used in production by thousands of community users, hundreds of customers and 75+ Global 2000…
I can't speak about Titan, but Neo4j HQ is in San Mateo and I'm more than happy to buy anyone lunch or caffeine and discuss graph databases. Neo4j is not the right choice for every situation. But according to most…
For more background info on what's holding back NOSQL in the enterprise and why we raised $10M+, feel free to check out this post: http://blogs.neotechnology.com/emil/2011/09/nosql-the-web-an...
Re: permissive, I concur! Poor wording on our part. Permissive-r than AGPL perhaps was our thinking. :) But you're absolutely correct that the GPL is not a permissive license. Updated the post! As for GPLv2 vs v3, in a…
The main feature (software-wise) in Neo4j Enterprise is High Availability clustering support, which gives you fault tolerance and read scalability. On top of that Neo4j Enterprise also comes with 24/7 enterprise-grade…
Please note that this post talks about Neo4j Community. Neo4j is now split into three editions: * Neo4j Community, a high performance, fully ACID transactional graph database – licensed under the GPL * Neo4j Advanced,…
How can we improve? We certainly don't want to hide our choice of licensing. Currently it's at the top of the http://neo4j.org page, immediately after the introductory description of a what a graph database is: "Neo4j…
Well, the data model seems very similar to Redis' from first glances [1], but FlockDB certainly seems to have completely different durability characteristics. So even if they started anew today they may end up building…
I agree that it's not apples/apples. From the first few minutes, I think the main strength of Neo4j is the rich ecosystem and functionality on top of it, and the fact that it stores an infinite-levels deep graph. In…
I haven't looked deeply into this particular project but I agree with you: the hypergraph data model seems to add too much complexity for too little bang compared to a generic graph model. The Neo4j graph database:…
For the Neo4j graph database, check out: * the 10 minute code-level getting started guide: http://wiki.neo4j.org/content/Getting_Started_Guide * a full-blown reference example, including diagrams, graph layout screen…
In Scandinavia, the typical length of a VC fund is actually 10 years with a standard option to extend for 2 years. First half (5 years) for new investments, second half for followups and then 2 years for padding (option…
I'm part of the Neo4j team and I'm puzzled about the import problem. I don't know about the size requirements you have but you mention 2.5M nodes and 60M edges and we run systems in production with a LOT more data…
