In this first post, we look at what exactly ArangoML is, with later posts in this series showcasing the different tools and use cases. If you have a use case you would like to see highlighted as a part of this series, please let us know on the ArangoML Slack channel. Overview ArangoML is a set of tools and technologies that enable analytics and machine learning on graph data.  ArangoML Tools/Stack The ... Read More

Feed: Blog – ArangoDB. Author: Max Neunhöffer. Recently, we decided to investigate why our application ARANGOSYNC for synchronizing two ArangoDB clusters across data centers used up a lot of memory – around 2GB in certain cases. The environment contained ~1500 shards with 5000 GOroutines. Thanks to tools like pprof (to profile CPU and memory usage) it was very easy to identify the issue. The GO profiler showed us that memory was allocated in the function time.After() and it accumulated up to nearly 1GB. The memory was not released so it was clear that we had a memory leak. We will explain ... Read More

With today’s GA release of ArangoDB 3.7, the project reached an important milestone on this journey. Join our Head of Engineering & Machine Learning on September 10th for the ArangoDB 3.7 Release Webinar. Graph & Beyond – An Important Milestone for Multi-Model Being a suitable solution for graph, document and key/value needs was our first milestone, which we reached several years ago. Providing this flexibility also at scale has ... Read More

Together with my team, I took a deep dive into the available fuzzy search approaches and algorithms for quite a while, in order to find a performant solution for the various projects ArangoSearch gets used for.  Since the introduction of ArangoSearch back in 2018, many of our users have asked for fuzzy search support. We worked hard on getting this done, and the whole team is now excited to finally make fuzzy search available with the upcoming ArangoDB 3.7. In the following, we will share our learnings and hope they are useful for ... Read More

Feed: Blog – ArangoDB. Author: Jan Stücke. Graph Databases are a great solution for many modern use cases: Fraud Detection, Knowledge Graphs, Asset Management, Recommendation Engines, IoT, Permission Management … you name it.  All such projects benefit from a database technology capable of analyzing highly connected data points and their relations fast – Graph databases are designed for these tasks. But the nature of graph data poses challenges when it comes to *buzzword alert* scalability. So why is this, and are graph databases capable of scaling? Let’s see… In the following, we will define what we mean by scaling, take ... Read More

The ArangoDB Query Language(AQL) was designed to accomplish a few important goals, including: Be a human-readable query languageClient independency Support complex query patternsSupport all ArangoDB data models with one languageThe goal of this guide is to ensure that you get the most out of the above design goals, by providing some suggested best practices. Just like many programming languages, AQL allows the developer to format their code in whatever way comes naturally to them. However, just like with programming languages, there are different style guides and best practices that the community agrees upon. These ... Read More
