ArangoDB Weekly 34: Updates, Tips, and Community Highlights

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 Raspberry Pi you should update to this new release. There is no need to update to 2.6.8 for other distributions.

You can find a full list of changes in our change-log (2.6.8)
