Anyone who has ever worked with our JavaScript framework Foxx was faced at some point with the challenge to install its Foxx service in its current ArangoDB instance or to replace the installed service with local code changes. This is not a big deal and can easily be done through ArangoDB’s WebUI. However, we developers always want to become more productive and clicking through a graphical UI is not the best way. Furthermore, this procedure is almost impossible to use in an automated deployment process. That’s why we decided to develop a node-based ... Read More

TL;DR; This describes how to generate a completely static binary for a complex C++ application which runs on all variants of Linux without any library dependency. ArangoDB is a multi-model database written in C++. It is a sizable application with an executable size of 38MB (stripped) and quite some library dependencies. We provide binary packages for Linux, Windows and MacOS, and for Linux we cover all major distributions and their different versions, which makes our build and delivery pipeline extremely cluttered and awkward. At the beginning of this story, we needed approximately 12 ... Read More

We are thrilled to be attending one of Europe’s greatest events – JontheBeach (JOTB), an international rendezvous for developers and DevOps around Big Data technologies. No product talks just deep-tech topics presented by hand-picked speakers from Google, Apache Spark, RedHat, Stripe, Microsoft and many more. One of our core developers, Max Neunhoeffer, has been to the conf last year and enjoyed the special atmosphere a lot. This year, we decided to jump on this rare opportunity to learn & connect and are a Gold Sponsor of the event. We would love you to ... Read More

You can browse and explore it interactively via the ArangoDB Webinterface. Working with the Swagger.io API Tool Now you’ve loaded the Swagger.io API documentation, let’s play with it. We’re choosing a route that accepts a simple JSON post document. Executing a simple AQL Query does so. As shown above, we scrolled down to AQL and clicked on POST /_api/query. It already shows a similar documentation as we could also see on the official HTTP API documentation page. Now we scroll down ... Read More

Feed: Blog – ArangoDB. Author: Ewout Prangsma. At ArangoDB we’ve got many requests for running our database on Kubernetes. This makes complete sense since Kubernetes is a highly popular system for deploying, scaling and managing containerized applications. Running any stateful application on Kubernetes is a bit more involved than running a stateless application, because of the storage requirements and potentially other requirements such as static network addresses. Running a database on Kubernetes combines all the challenges of running a stateful application, combined with a quest for optimal performance. This article explains what is needed to run ArangoDB on Kubernetes and ... Read More

Cluster Administration course will take you all the way from concept and anatomy of the ArangoDB cluster to maintenance, resilience and troubleshooting of your distributed environment. When data size or workload makes purchasing of a single database server prohibitive one needs to rethink the system architecture and consider to cluster a farm of more affordable machines. While ArangoDB clusters bring additional added value like seamless runtime scaling and thin provisioning, their management can look testy and challenging. We have tried to make the experience of bootstrapping, maintenance and operation of an ArangoDB cluster ... Read More

Feed: Blog – ArangoDB. Author: Jan Steemann. This article is about setting up active failover for ArangoDB-PHP, the PHP client driver for ArangoDB. It requires ArangoDB-PHP 3.3.2 or higher, and an ArangoDB server version of 3.3.4 or higher. Active failover: basic setup Historically, ArangoDB-PHP has been able to connect to a single ArangoDB endpoint, i.e. one combination of IP address and port number. To connect to an ArangoDB server that is running on localhost or on a remote server, simply set the OPTION_ENDPOINT item in the ConnectionOptions and connect: php namespace ArangoDBClient; // following can be omitted when composer.json is ...

In the first part of this article we dived deep into what indexes are currently available in ArangoDB (3.2 and 3.3), also briefly looking at what improvements are coming with ArangoDB 3.4. Read the full article here. In this Part II, we are going to focus on how to actually add indexes to a data model and speed up specific queries. Adding indexes to the data model The goal of adding an extra index to the data model is to speed up a certain query or even multiple queries. One of the first ... Read More

Feed: Blog – ArangoDB. Author: Claudius Weinberger. Recently, we published the latest findings of our Performance Benchmark 2018 including Neo4j, PostgGreSQL, MongoDB, OrientDB and, of course, ArangoDB. We tested bread & butter tasks in a client/server setup for all databases like single read/write and aggregation, but also things like shortest path queries which are a speciality for graph databases. Our goal was and is to demonstrate that a native multi-model database like ArangoDB can at least compete with the leading single model databases on their home turf. Traditionally, we are transparent with our benchmarks, learned plenty from community feedback and ... Read More
