In this blog post – which is a roundup of the performance blog series – I want to complete the picture of our NoSQL performance test and include some of the supportive feedback from the community. First of all, thanks for all your comments, contributions and suggestions to improve this open source NoSQL performance test (Github). This blog post describes a complete overhaul of the test with no need to read all the previous articles to get the picture – have a look at the appendix below to get all the details on..

Long awaited and now we´ve finished it! New major release of ArangoDB 2.7 is ready for download. First of all a big thanks to our community for your great support! We´ve implemented a lot of your ideas! After your feedback to RC1 and RC2 we are happy to bring a new major release to the world. With ArangoDB 2.7 we increased our performance even further and improved query handling a lot.

What big improvements are in for you?

Index buckets

In ArangoDB 2.6.9 we have fixed an AQL skiplist issue that occurs in a combination of sort and limit.

We put a lot of brainpower into the next major release of our favorite database. Thanks to your feedback and contributions we got some important steps forward. Share your professional experiences, opinions and feedback with us on this release candidate of ArangoDB 2.7.

This is a quick info about the upcoming 2.7 release – for details please check our documentation and the changelog.

Performance

As performance and ease of use are part of our key goals, we worked hard on some major improvements. Thanks to your feedback and contributions we were able to implement some nice stuff like:

In just a few days we will publish our release candidate of ArangoDB 2.7. As secure performance and ease of use are our key goals, we worked hard on some nice improvements like

• Index Buckets (Reducing loading time for collections and enable faster resizing)
• Throughput Enhancements (Real world tests showed 25-75% increase of throughput compared to 2.6)
• Enhancements for AQL like “return distinct”, “template query strings” or the brand new “AQL query result cache”

So stay tuned!

ArangoDB Releases

The release ArangoDB 2.6.8 fixes a memory access bug on ARM. So for your pet project on a..

While preparing the release of ArangoDB 2.7, some improvements were made for the PHP driver for ArangoDB.

The 2.7 version of the PHP driver now supports the AQL query results cache. The cache can be turned on or off globally, or be set to demand mode. The demand mode will allow controlling caching on a per-AQL-query basis.

The release ArangoDB 2.6.8 fixes a memory access bug on ARM. So for your pet project on a Raspberry Pi you need to change the CPU alignment setting to allow unaligned memory access.

There is no need to update to 2.6.8 for other distributions.

ArangoDB is available as Amazon Marketplace Image (AMI) for free.

The first alpha of the official JavaScript driver arangojs‘ upcoming major release is now available on npm.

Version 4 streamlines the driver’s API by removing unnecessary server roundtrips to obtain references to collections and graphs that already exist:

Before:

var db = require('arangojs')(); db.collection('users') .then(function(collection) { return collection.import(allTheUsers) }) .then(function() { return db.collection('blogs') }) .then(function(collection) { return collection.import(allTheBlogs); }) .then(function() { return db.collection('articles') }) .then(function(collection) {..

I recently wrote two recipes about generating AQL query strings. They are contained in the ArangoDB cookbook by now:

• Avoiding parameter injection in AQL
• Writing multi-line AQL queries

After that, Github user tracker1 suggested in Github issue 1457 to take the ES6 template string variant even further, using a generator function for string building, and also using promises and ES7 async/await.

We can’t use ES7 async/await in ArangoDB at the moment due to lacking support in V8, but the suggested template string generator function seemed to be an obvious improvement that deserved inclusion in..
