Static binaries for a C++ application
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 hours just to build and publish a release, if everything goes well. This is the beginning of a tale to attack this problem. Read more

ArangoDB Easter Egg Hunt: Join the Fun and Discover Surprises!
While working hard on the next release and hacking away new interesting things to include into our favourite database, we decided to take a short break to have some fun just in time for Easter. All teams gathered together to do some Easter eggs coloring, chocolate-eating and fun-having 🙂
We’ve colored a lot of eggs in our favourite colors – green and brown, and hid them all around our office and beyond. Now, here is a little challenge for you to help us find them. Read more

The ArangoDB Operator for Kubernetes – Stateful Cluster Deployments in 5min
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 what we’re doing to make it a lot easier.

ArangoDB Cluster Administration Course Released
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. Read more
Configuring ArangoDB-PHP to use active failover
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: Read more
Index types and how indexes are used in ArangoDB: Part II
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 Part I 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 things that should be done during development of AQL queries should be to review the output of the explain command. A query can be explained using ArangoDB’s WEB UI or from the ArangoShell. In the ArangoShell it is as simple as db._explain(query), where query is the AQL query string. To explain a query which also has bind parameters, they need to be passed separately into the command, e.g. db._explain(query, bindParameters).

How We Wronged Neo4j & PostgreSQL: Update of ArangoDB Benchmark 2018
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 want to keep it that way. Unfortunately, we did something wrong in our latest version and this update will explain what happened and how we fixed it. Read more
