A maintenance release for ArangoDB 2.4.2 is available for download or via your favourite package manager.

v2.4.2 (2015-01-30)

• added custom visitor functionality for AQL traversals

This allows more complex result processing in traversals triggered by AQL. A few examples are shown in this article.

• improved number of results estimated for nodes of type EnumerateListNode and SubqueryNode in AQL explain output

Jan blogged about some recent extensions for the AQL graph traversal functionality in ArangoDB. These extensions allow invoking user-defined JavaScript code for filtering and results generation in AQL queries that contain traversals.

We have moved our ArangoDB Github repository from triAGENS to arangodb.

We are working hard to improve usability and simplify the usage of Foxx which will be shipped with version 2.5. of ArangoDB.

We have learned from the past and collected a lot of feedback, thanks to all people using Foxx already. It helped us to identify the following three important areas of Foxx that should be improved:

1. Debugging of Foxx apps
2. Getting started with Foxx
3. Development ModeArangoDB 2.5 has updates ready for all of these points. Just as a teaser we have backported one of the new features into ArangoDB 2.4 which will be included from 2.4.2 onwards: Most of you who already used Foxx..

With the ArangoDB Foxx Microservice Framework we’ve introduced an easy way to create a Web API right on top of the NoSQL database.

In early January Max challenged Andreas (AngularJS / NodeJS) that they could build a full-stack application within half a day.

The web application – in short – is a guessing game, in which the computer tries to guess a thing or animal you think of by asking a series of questions, for which you provide the answers. Here’s a demo:

I have been looking at many AQL queries during the last few weeks…

Looking back, I can say that the JSON query execution plans provided by the explain() method have provided me with a lot of useful information about how the AQL optimizer had transformed a given query. This has helped testing and improving the query optimizer a great deal.

However, the JSON output produced by explain() is so detailed that even for the simplest cases queries it will span multiple screens. This is far too much for quickly assessing what a query will be doing and how it will be executed.

I therefore quickly put..

ArangoDB provides many options for finding and modifying data. Though there are several more specialized operation, data-modification AQL queries are the most general solution in ArangoDB. They allow to find documents using arbitrary filter criteria, and to modify or remove the documents once found.
