We want to present you our growing documentation. A few weeks ago we published the new documentation with a completely new look and a far better structure than before.

Since than we fixed some small issues and rewrote some of the sections. In addition you can fold the code examples for a better overview. Now these code examples will be generated before the release of a new documentation. Because of that the code will be accurate. Now you have the possibility to download .epub or .mobi for your ebook-reader. This way you can explore ArangoDB comfortable on a trip even if you have no internet.

With the 2.2 release we proudly announce that we now offer the feature of multi collection graphs. This allows you to group an arbitrary set of ArangoDB collections into one graph. In order to do this grouping you execute the following steps in arangosh or Foxx: 1. Require the general-graph module and create a graph.

var graph_module = require("org/arangodb/general-graph");
var graph = graph._create("myGraph");

1. Add collections to be used as vertex collections. If the collections are not yet created, ArangoDB will create them..

We are happy to announce the release of 2.2.0. All the open issue mentioned in the beta release are now fixed.

Features and Improvements The following list shows in detail which features have been added or improved in ArangoDB 2.2. ArangoDB 2.2 also contains several bugfixes that are not listed here.

AQL improvements

Data modification AQL queries Up to including version 2.1, AQL supported data retrieval operations only. Starting with ArangoDB version 2.2, AQL also supports the following data modification operations:

• INSERT:..

ArangoDB comes with a powerful query language, called AQL. It combines all the different aspects in any easy-to-use query language. You can use joins as in SQL or graph queries as in Cypher. However, up to now it only supported read-queries.

FOR u IN users 
  FOR c IN cities 
    FILTER u.zip == c.zip 
    RETURN { 'name': u.name, 'city': c.name }

Allows you to join the name of city a persons lives in. If you want to follow the social graph and mix in the neighbors, simply add a graph query.

FOR u IN users FOR c IN cities FILTER u.zip == c.zip RETURN { 'name': u.name, 'city': c.name, 'knows':..

ArangoDB has an HTTP interface to talk to its clients. Sometimes people want to secure this connection and use SSL or TLS instead. That is where we are using OpenSSL. It provides all the methods to implemented HTTPS on top of an HTTP server. It worked well and the corresponding code is only some 300 lines of C++ code. The biggest obstacle was the documentation. You can basically only learn from examples. That’s what we did. However, we finally encountered a bizarre bug. ArangoDB uses a number of threads to handle I/O in an asynchronous manner. The underlying library for I/O is libev. We span..

We are proud to announce the beta release of ArangoDB 2.2. It is a major step forward, improving the usability of AQL and graphs a lot. As always, a lot of small improvements are incorporated into your favourite NoSQL database – we will list them in a separated blog entry. However, the three major improvements are

Dear ArangoDB users, we are proud to announce our new manual for ArangoDB. It is a complete overhaul, with huge changes and improvements, which became necessary because the old manual grew so fast and was edited by so many people, that it became inconsistent. We would appreciate if you could give us feedback. Either by writing comments in the google groups or by opening issues in the GitHub repository.
