The fans of modern and agile software development usually propose to use schemaless database engines to allow for greater flexibility, in particular during the early rapid prototyping phase of IT projects. The more traditionally minded insist that having a strict schema that is enforced by the persistence layer throughout the lifetime of a project is necessary to ensure quality and security.In this post I would like to explain briefly, why I believe that both groups are completely right and why this is not so paradoxical as it sounds at first glance. I am one of the developers of ArangoDB,..

Aside from the more noticeable features, ArangoDB 2.5 also added the console object to the scope of all Foxx app modules. Unlike the object already available by importing the console module, the Foxx console logs all messages directly to the database.

ArangoDB 2.4.5 is ready to download. The latest release of the 2.4 branch comes with some minor bugfixes and a new feature:

Tracking of AQL queries

We have added current and slow query tracking and also killing of long running AQL queries.

This change enables retrieving the list of currently running AQL queries inside the selected database. AQL queries with an execution time beyond a certain threshold can be moved to a slow query facility and retrieved from there:

We are proud to announce the latest release of ArangoDB, adding a bunch of new features and lot’s of improvements to existing ones. ArangoDB 2.5 is available for download now and could be installed from your favourite package manager.

See the previous blogposts on sparse indexes performance, ES6 features in ArangoDB, improved Foxx development process or API Key management to learn more about ArangoDB 2.5 and check the manual for a deeper dive into specific features.

The AWS image of ArangoDB 2.5 will be available shortly.

I often find myself searching for certain commits using git log and friends. While I really love the power and flexibility that come with the git and other Unix command-line tools, sometimes it can be more convenient to use a database to filter and aggregate commit data.

I gave it a quick try yesterday and imported the commit history of ArangoDB’s Git repository into ArangoDB and ran some queries on the data.

Great to know your database scales and database vendors like ArangoDB add some statistics on node / cluster health directly in their products.

But running a bunch of different servers and applications you need a central hub to collect monitoring data from all services running. In a series of recipes Willi shows how you could easily add monitoring capabilities to NoSQL databases like ArangoDB using collectd with the cURL JSON plugin.

ArangoDB’s Foxx allows you to easily build an API to access your data sources. But now this API is either public or restricted to users having an account, but those still get unlimited access.

In many use cases you do not want to expose your data in this fashion, but you want to expose it with a more controllable access pattern and want to restrict the requests one user could issue in a certain time period. Popular examples for these API restrictions are Twitter or Facebook. This allows you to offer all of your data but only in limited chunks, and then possibly charge your customers to..

Version 2.5 of ArangoDB makes the development of Foxx based apps a lot easier.

For each of your Foxx apps you could activate the development mode individually, forcing a reread from disk at every request, and providing additional debug output. Set the development mode for an app doesn’t change the mount-point anymore. The Foxx source location on your filesystem is now identical with the mount-point of your app.

Contained in 2.5 are some small but useful AQL language improvements plus several AQL optimizer improvements.

We are working on further AQL improvements for 2.5, but work is still ongoing. This post summarizes the improvements that are already completed and will be shipped with the initial ArangoDB 2.5 release.

ArangoDB 2.5 comes with an upgraded version of V8, Google’s open source JavaScript engine.

The built-in version of V8 has been upgraded from 3.29.54 to 3.31.74.1.
