ArangoDB Weekly 32: Updates, Tips, and Community Highlights

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).
