ArangoDB 3.2 GA
RocksDB, Pregel, Fault-Tolerant Foxx & Satellite Collections

00General, ReleasesTags:

We are pleased to announce the release of ArangoDB 3.2. Get it here. After an unusually long hackathon, we eliminated two large roadblocks, added a long overdue feature and integrated an interesting new one into this release. Furthermore, we’re proud to report that we increased performance of ArangoDB on average by 35%, while at the same time reduced the memory footprint compared to version 3.1. In combination with a greatly improved cluster management, we think ArangoDB 3.2 is by far our best work. (see release notes for more details)

One key goal of ArangoDB has always been to provide a rock solid platform for building ideas. Our users should always feel safe to try new things with minimal effort by relying on ArangoDB. Todays 3.2 release is an important milestone towards this goal. We’re excited to release such an outstanding product today. Read more

A Reminder on Database Security


With billions of objects and people connected to the internet and your precious data sometimes exposed publicly security is one of the most important topics to discuss. In light of recent ransomware attacks, databases exposed and other breaches we’d like to share a quick reminder on how to secure your ArangoDB environment.

Attacks can be prevented with the security protections built into the product. We strive to prevent possible security issues by giving appropriate reminders in our web console when authentication is disabled:

Introducing milestone release model and why is it better

00General, ReleasesTags:

When developing ArangoDB, we want to share with you new features as early as possible. For example, the pregel implementation that will become part of ArangoDB 3.2 was ready for testing weeks before the release date of the first beta release and the final release of 3.2.

Therefore we decided to create intermediate releases, called alpha releases, which contain new feature as early as they became stable. The benefits for the community and also for our developers team are: Read more

Dockerizing a Bloom-based Nonces Service in 10 Minutes

00Documentation, Foxx

In this article I want to explain how to setup a nonce-microservice using docker.

Nonce are one-time tokens that are used to ensure that an action can only be taken once. In a project, we needed to ensure that a pay button is only pressed once. Note that nonces are not used to sign requests or identify a user. This is a separate mechanism.

ArangoDB contains a nonce implementation which is a variation of Bloom-filters. It allows to store nearly unlimited nonces within a limited amount of memory. Nonce are allowed to age, that is after an hour they might expire. If there is sufficient interest, I will explain the algorithm implemented in a separate blog post.

How an open-source competitive benchmark helped to improve databases

017General, Performance

TL;DR: Our initial benchmark has raised a lot of interest. Initially we wanted to show that multi-model can compete with other solutions. Due to the open and competitive way we have conducted the benchmark, the discussions around it have lead to improvements in all products, better algorithms, faster drivers and better ways to use the databases.

General Setup

From the outset we published all code and data and asked the vendors of all tested products as well as the general public, not only to run the tests on their own machines, but also to suggest improvements in the data models, test code, database configuration, driver usage and server configuration. This lead to a lively discussion, lots of pull requests and even to the release of improved versions of the database products themselves!

This process exceeded all our expectations and is yet another great example of community collaboration not only for fact finding but also for product improvements. Obviously, the same benchmark code will always show slightly different results when run on different hardware, operating systems, network setups and with more or less RAM. Therefore, a reliable result of a benchmark can essentially only be achieved by allowing everybody to run it on their own machines.

The technical setup is described in the above blog post. Let me briefly repeat the key facts.

ArangoDB 2.4: EcmaScript 6, AQL Speedup and Hypermedia API Builder


This version is deprecated. Download the new version of ArangoDB

We are proud to announce the release of Version 2.4 of our multi-model database ArangoDB. It’s ready for download now and available for all major platforms.

This release is a major step forward. Use Foxx to create your favorite microservice with a few clicks, dockerize it and access it via a REST/Web API from everywhere. – Dr. Frank Celler (CTO)

You can now use EcmaScript 6 features like iterators, symbols, maps and sets by default and enable even more ES6 features with ArangoDB start options. The V8 engine upgrade in ArangoDB 2.4 also improves performance and speeds up V8 garbage collections.

The ArangoDB query language (AQL) gets more efficient group count calculation queries, an optional return value for AQL data-modification queries and improved index handling in filtering AQL queries.

Foxx 2.0: The new Foxx-Generator is a framework that enables developers to build Hypermedia APIs easily. Developers can create Web APIs based on a semantic description of entities and transitions using a statechart alike design approach. Additional to the recently added job queues and authentication services, Foxx got a new web-frontend to easily create new or install Foxx applications from Github or the ArangoDB Store.

Try the new tutorial Foxx in 10 Minutes to build your first Foxx application. Starting with a new Foxx app has never been easier.

Along with ArangoDB the new light-weight JavaScript driver arangojs 3.0 is ready to use.

Download the current 2.4 release and start building your own applications on top of ArangoDB!
