Document Update with arangoimp: ArangoDB Data Management
Inspired by the feature request in Github issue #1298, we added update and replace support for ArangoDB’s import facilities.
This extends ArangoDB’s HTTP REST API for importing documents plus the arangoimp binary so they can not only insert new documents but also update existing ones.
Inserts and updates can also be mixed in a single import run. What exactly will happen is configurable by setting arangoimp’s new command-line option --on-duplicate.
By default, error will be reported if a document already exists. This behavior can be changed by setting --on-duplicate to a value of update, replace or ignore. Here is an example result of an import with duplicated keys:
> arangoimp --file data.json --collection users --on-duplicate update
created: 1
warnings/errors: 0
updated/replaced: 2
ignored: 0
So, if you want to aggregate data from several data files, you can try the new import command-line option --on-duplicate.

Documentation Review & Roadmap: ArangoDB Updates
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.
The foundation of our new documentation is build and we think it will help you to understand ArangoDB and its functions. Of course there are some plans for the near future to make our documentation more extensive.
We want to make the documentation even more clearer. So you can find everything you desire as soon as possible. It is planned to add an extra subchapter in most of the chapters with a list of all functions. This way you have a better overview about all functions with a brief explanation. With this list you don’t have to scroll through a whole chapter to find a specific function.

You can find our new manual here.
Changes highlights:
- Everything in one place: user manual, developers manual and adminstrators manual
- Completely new, consistent and themable design
- Improved navigation through sidebar
