First of all, we want to send a biiiiig “Thank You!” to all the testers so far and all your feedback! Super helpful for us! This Release Candidate post is dedicated to the four new features of ArangoSearch which extend the capabilities and provide pretty huge performance improvements, especially for queries including search & sorting. Probably the most interesting new thing you can do (and the most requested) is to configure analyzers and provide custom stopword-lists among other configuration ... Read More

Feed: Blog – ArangoDB. Author: Jan Stücke. This has been a really momentous year so far for us, filled with a lot of accomplishments we’re pretty excited about. We recently added another one to the books: being named to Database Trends and Applications magazine’s “DBTA 100: The Companies That Matter Most in Data” list. What does this mean? Well for us, it’s just a bit more validation that we’ve been able to help developers around the world reduce complexity and headaches that typically accompany leveraging multiple data models within their applications. We truly believe that developers and their teams are ... Read More

Feed: Blog – ArangoDB. Author: Christopher Woodward. When looking for a solution for your project, it is important to understand what makes each technology unique, what sets it apart. With ArangoDB that is its native multi-model approach including full graph database capabilities and I am going to explain the fundamental pieces of what that means. Using ArangoDB as a Graph Database If you are already familiar with the graph database concept, then you know that a graph consists of vertices (or nodes) connected via edges. Graph databases usually store edges connected to vertices directly at the vertex object. In ArangoDB ... Read More

If you are a company or organization in the health services industry and you work with personal patient data, then you have most probably heard about HIPAA compliance. The Health Insurance Portability and Accountability Act (HIPAA) is a law passed in 1996 by US Congress that sets standards and protocols for the protection of patient data in the healthcare industry. Many of our users and customers asked us about building HIPAA compliant applications ... Read More

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: Blog – ArangoDB. Author: Daniel Larkin-York. Sometimes we want sorted output from a query and, for whatever reason, cannot use an index to do the sorting. In ArangoDB, we already cover this critical case with finely tuned query execution code. Sometimes though, we do not need to return all output, and follow our SORT clause with a LIMIT. In ArangoDB 3.4 and earlier, we did not handle this case any differently from returning the full data, at least with respect to sorting – we would sort the full input, then apply the limit afterwards. In many cases though, it is possible to ... Read More

Feed: Blog – ArangoDB. Author: Simon Grätzer. With ArangoDB 3.4 we finally made the rocksdb storage engine the default. This decision was made after a year of constant improvements to the engine to make it suitable for all our customer’s use cases. Improved Read / Write-Performance We massively improved the binary on-disk storage format with the 3.4 release. This format allows inserting new documents in an order that RocksDB prefers. Using the new format will reduce the number of compactions that RocksDB needs to do for the ArangoDB documents stored, allowing for better long-term insertion performance. The sustained insertion performance ... Read More
