ArangoDB is a scalable, distributed multi-model database. However, for this talk, it is not necessary to know what this means. Rather the only crucial fact is that it is distributed and written in C++.

Before you stop reading: This talk is about a golang success story.
Namely, we had to implement resilient data center to data center (DC2DC) replication for ArangoDB clusters from scratch within 6 weeks (plus some time for testing and debugging). Therefore, we built upon
– ArangoDB’s HTTP-based API for asynchronous replication,
– the existing golang driver,
– the fault tolerant scalable message queue system Kafka,
– a lot of existing golang libraries and
– golang’s fantastic capabilities for parallelism, communication and data manipulation

and pulled this task off. This talk is the story of this project with its many challenges and successes and ends with a surprising revelation about which of the above we did not actually need in the end.

ArangoDB is a scalable, distributed multi-model database. It can be deployed on many operating systems in various environments.

In recent months we’ve received many requests to support Kubernetes “out of the box”.

This talk is about an ongoing journey from early yaml files to an advanced integration supporting scaling, upgrading and monitoring in a devops friendly way.

The journey will take us from tiny cloud environments to bespoke hardware, touching subjects such as persistency performance, session stickyness, access control and federation.

Our journey has not reached its destination yet, but the destination looks promising and the journey so far has been an interesting one, that we will happily share with you.
