In the last two weeks we’ve fixed some issues, upgraded the bundled V8 version in ArangoDB and released the maintenance release 2.6.5 and 2.6.7 . Besides that we continued our efforts to enhance our indexing capabilities and startet further cluster tests.

ArangoDB Release

The next maintenance release for ArangoDB 2.6 is available for download. You can find a full list of changes in our change-log (2.6.7) and change-log (2.6.5).

In the past two weeks we’ve celebrated some lock-hunting days, trying to eliminate read/write locks to enhance throughput . Furthermore, we did some large cluster tests on GCE, which will be continued over the next days. A maintenance release of ArangoDB 2.6, released earlier this week, comes with a new V8 engine.

ArangoDB Releases

Two maintenance releases are available. ArangoDB 2.5.7 and ArangoDB 2.6.4 use an upgraded V8 engine (4.1.0.27).

Motivation

In multi-threaded applications running on multi-core systems, it occurs often that there are certain data structures, which are frequently read but relatively seldom changed. An example of this would be a database server that has a list of databases that changes rarely, but needs to be consulted for every single query hitting the database. In such situations one needs to guarantee fast read access as well as protection against inconsistencies, use after free and memory leaks.

Therefore we seek a lock-free protection mechanism that scales to lots of threads on modern machines and..

We’ve recently been working on improving ArangoDB’s throughput, especially when using the ArangoDB’s interface.

In this post, I will show some of the improvements already achieved, though the work is not yet finished. Therefore, the results shown here are still somewhat preliminary.

We wanted to measure improvements for ArangoDB’s HTTP interface, and so we used wrk as an external HTTP load generator.

During the tests, wrk called some specific URLs on a local ArangoDB instance on an otherwise idle machine. The test was run with ArangoDB 2.6 and devel. The ArangoDB instances were started with..

ArangoDB Version 2.6.4 comes with an upgraded V8 engine (4.1.0.27) and is ready to download now. In the 2.5 branch we’ve published a 2.5.7 maintenance release as well.

ArangoDB allows running user-defined JavaScript code in the database. This can be used for more complex, stored procedures-like database operations. Additionally, ArangoDB’s Foxx framework can be used to make any database functionality available via an HTTP REST API. It’s easy to build data-centric microservices with it, using the scripting functionality for tasks like access control, data validation, sanitation etc.

We often get asked how the scripting functionality is implemented under the hood. Additionally, several people have asked how ArangoDB’s JavaScript functionality relates to..

ArangoDB is now an Official Repo in the Docker Hub, one of just four additions in the last 2 months. Please try and tell your friends! ArangoDB 2.6 is known as a performance release and we’ve continued to improve the core by killing locks and optimizing code. Looks like we can show some impressive performance boosts soon. Furthermore, Mike Williamson wrote a blog post on modeling data with ArangoDB last week, that is worth to read.

ArangoDB’s devel branch recently saw a change that makes writing some AQL queries a bit simpler.

The change introduces an optional shorthand notation for object attributes in the style of ES6’s enhanced object literal notation.
