Feed: Blog – ArangoDB. Author: Heiko Kernbach. Geo data is getting more and more important for today’s applications. The growing number of location-aware services, IoT applications and other solutions using latitude and longitude ask for precise and fast processing of geo data. Let me show you in this quick demonstration how you can use geo functions and visualize your data using Foxx and leaflet.js. Installation First install the Foxx Service hosted on GitHub: https://github.com/arangodb-foxx/demo-geo To do that, simply open the ArangoDB Web UI and install either via the GitHub method or download the zip-file and import it. After the finished ... Read More

Feed: Blog – ArangoDB. Author: Max Neunhöffer. Recently I gave a talk about ArangoDB in front of a community of mathematicians. I advertised that nearly arbitrary data can “easily” be stored in a JSON based document store. The moment I had uttered the word “easily”, one of them asked about long integers. And if a mathematician says “long integer” they do not mean 64bit but “properly long”. He actually wanted to store orders of finite groups. I said one should use a JSON UTF-8 string for this but I should have seen the next question coming because he then wanted ... Read More

Join our Sr Distributed System Engineer, Kaveh Vahedipour, to learn more about ArangoDB Agency on September 19th, 2017 (6PM CEST/12PM ET/ 9AM PT) – Join the webinar here.Distributed systems have become the standard topology on which modern appliances live. While the advantages of distributing workload for both performance as well as fault-tolerance are obvious, the runtime flexible configuration of such deployment becomes non-trivial.ArangoDB clusters are no different in that regard. A potentially large database cluster’s configuration is manipulated at runtime by addition, alteration and removal of collections, indexes, and even servers. All servers ... Read More

Feed: Blog – ArangoDB. Author: Mark Vollmary. With the 3.2 release, ArangoDB comes with version 1.1 of the binary protocol VelocyStream. VelocyStream is a bi-directional async binary protocol which supports sending messages pipelined, multiplexed, uni-directional or bi-directional. The messages themselves are VelocyPack objects. The story of VelocyStream began with version 3.0 of ArangoDB which introduced VelocyPack as the new internal storage format of ArangoDB. VelocyPack as a binary format – which stores a superset of JSON, is more compact and has a fast attribute lookup – allows us to use the same byte sequence of data for storage, read-only work ...

Feed: Blog – ArangoDB. Author: Jana Volkova. “By developers for developers” has been our internal motto since the first lines of ArangoDB code. Building an open-source project at such level of complexity and at a market competitive standard, undoubtedly puts a lot of pressure and almost solely relies on the support and trust of the community.Every victory counts, be it small appreciation or big success – it’s what gives us inspiration and keeps us going forward. A while ago we’ve been having one of those rainy gray days here in Cologne. Receiving over 10 stars put a smile on faces ... Read More

Feed: Blog – ArangoDB. Author: Max Neunhöffer. With the new Version 3.2 we have introduced a new feature called “Satellite Collections”. This post explains what this is all about, how it can help you, and explains a concrete use case for which it is essential.Background and OverviewJoin operations are very useful but can be troublesome in a distributed database. This is because quite often, a join operation has to bring together different pieces of your data that reside on different machines. This leads to cluster internal communication and can easily ruin query performance. As in many contexts nowadays, data locality ... Read More

Feed: Blog – ArangoDB. Author: Frank Celler. We are pleased to announce the release of ArangoDB 3.2. Get it here. After an unusually long hackathon, we eliminated two large roadblocks, added a long overdue feature and integrated an interesting new one into this release. Furthermore, we’re proud to report that we increased performance of ArangoDB on average by 35%, while at the same time reduced the memory footprint compared to version 3.1. In combination with a greatly improved cluster management, we think ArangoDB 3.2 is by far our best work. (see release notes for more details)One key goal of ArangoDB has ... Read More

Just in time for the upcoming 3.2.0 release, we have updated the graphql-sync module for compatibility with graphql-js versions 0.7.2, 0.8.2, 0.9.6 and 0.10.1. The graphql-sync module allows developers to implement GraphQL backends and schemas in strictly synchronous JavaScript environments like the ArangoDB Foxx framework by providing a thin wrapper around the official GraphQL implementation for JavaScript.As a long-term database solution, ArangoDB is committed to API stability and avoids upgrades to third-party dependencies that would result in breaking changes. This means ArangoDB will continue to bundle the graphql-js 0.6.2 compatibility version of graphql-sync.However in order to ... Read More
