Feed: Blog – ArangoDB. Author: Willi Goesgens. This is an update of the 2016 blog post How to put ArangoDB to Spartan-Mode. A lot of things have changed in the last years. We moved our API implementation from JavaScript to C++. ArangoDB now has a new (default) storage engine, namely RocksDB instead of MMFiles. RocksDB is a great storage engine. However, it also trades memory for speed. If you start with the default configuration you might end up with using much more memory for ArangoDB than expected. Therefore let’s focus on our new storage engine, and make a configuration to ... Read More

Feed: Cambridge Intelligence. Author: Christian Miles. Finding an effective way to visualize connected data isn’t easy.Focus too much on producing something that looks good and you might lose sight of the meaning behind the data. Concentrate solely on the graph data itself and you may end up with an ugly chart that’s hard to interact with. Striking the balance is key.There are so many visualization options to choose from. In this post, we examine the pros and cons of one popular choice: chord diagrams.Done well, these circular diagrams with arcs between nodes can make a great impact. We’ll explore how ... Read More
