In October 2021 ArangoDB raised 27.8 million dollars in series B funding led by Iris Capital. In March 2019 ArangoDB raised 10 million dollars in series A funding led by Bow Capital. In January 2017 ArangoDB raised a seed round investment of 4.2 million Euros led by Target Partners. The word "arango" refers to a little-known avocado variety grown in Cuba.

Later, they changed the name to ArangoDB. They originally called the database system “A Versatile Object Container", or AVOC for short, leading them to call the database AvocadoDB. was founded in 2015 by Claudius Weinberger and Frank Celler. ArangoDB is a NoSQL database system but AQL is similar in many ways to SQL. AQL is mainly a declarative language and allows the combination of different data access patterns in a single query. ArangoDB is a multi-model database system since it supports three data models (graphs, JSON documents, key/value) with one database core and a unified query language AQL (ArangoDB Query Language).

In this post we will provide a brief introduction to ArangoDB’s Pregel module by guiding you through the implementation of an example algorithm.Multi-model database, Graph database, Document-oriented database, Key/Value database, Full-text Search EngineĪrangoDB is a free and open-source native graph database system developed by ArangoDB Inc. Please be advised that the implementation is still in an early phase and very like to change. You need to check-out the pregel branch of ArangoDB in order to play with the following examples. We started to implement an experimental version of Pregel in ArangoDB. The algorithm terminates when there are no more active vertices left and no message has been sent. These messages can be received by the other vertex in the next step. In each step the vertices can send messages to each other to distribute information. This means that the user’s algorithm is executed step wise on each server in the cluster in parallel for all its local vertices. We came up with a new ArangoDB module (called pregelRunner) that enables the user to write own algorithms, pass them to ArangoDB and have them executed in a Pregel-like fashion. So we set up an ArangoDB cluster, created some huge graphs and started evaluating the concept.

Please see a technical article about our current Pregel integration in our blog, details about the various Pregel algorithms ArangoDB supports in our documentation and a t utorial about Community Detection with real data in our training center.Įver since Google introduced Pregel as a system for large-scale graph processing we thought of a way how to enable this feature in ArangoDB. This post is outdated, please see more recent infos below. With the new job queues feature you can run async jobs to communicate with external services, Foxx queries make writing complex AQL queries much easier and Foxx sessions will handle the authentication and session hassle for you. We can’t wait to get your feedback, so we’ve released some great new Foxx features in 2.3 with more to come in the next release. Have a look at Jan’s blog post “ Tour around new AQL query optimizer” or read the optimizer documentation to get familiar with this new feature. We have tried to keep the new version as compatible as possible with ArangoDB 2.2. The query optimizer can now apply much more optimizations than in previous versions of ArangoDB. Especially the optimization of distributed queries has been improved significantly. The query optimizer and executor for AQL queries have been completely overhauled. ArangoDB 2.3 is available for Linux, Windows and Mac and provides support for 16 programming languages.

We are proud to announce the release of ArangoDB 2.3, available for download now. The new query optimizer is ready to rock the world.
