Recently, we decided to investigate why our application ARANGOSYNC for synchronizing two ArangoDB clusters across data centers used up a lot of memory – around 2GB in certain cases. The environment contained ~1500 shards with 5000 GOroutines. Thanks to tools like pprof (to profile CPU and memory usage) it was very easy to identify the issue. The GO profiler showed us that memory was allocated in the function time.After() and it accumulated up to nearly 1GB. The memory was not released so it was clear that we had a memory leak. We will explain ... Read More

Together with my team, I took a deep dive into the available fuzzy search approaches and algorithms for quite a while, in order to find a performant solution for the various projects ArangoSearch gets used for.  Since the introduction of ArangoSearch back in 2018, many of our users have asked for fuzzy search support. We worked hard on getting this done, and the whole team is now excited to finally make fuzzy search available with the upcoming ArangoDB 3.7. In the following, we will share our learnings and hope they are useful for ... Read More

But the nature of graph data poses challenges when it comes to *buzzword alert* scalability. So why is this, and are graph databases capable of scaling? Let’s see… In the following, we will define what we mean by scaling, take ... Read More

However, just like with programming languages, there are different style guides and best practices that the community agrees upon. These ... Read More

One of them is that the current vaccine and drug development process takes a lot of time. Some would even say too long for having the desired impact on containing the spread. Source: Own representation based on IFPMA 2019 There are for sure elements in the vaccine development process shown above that can’t be done much faster in order to develop a safe and effective vaccine. But for other steps, modern technology ... Read More
