Neo4j, an open-source graph database, is now available as a package on Mesosphere's DC/OS platform, allowing users to easily deploy and manage the database across large clusters. The joint effort between Johannes, a Neo4j user and community contributor, and Michael, who joined Mesosphere in Hamburg, made this possible by publishing Neo4j as a package for running on DC/OS using its Marathon scheduler. This simplifies the process of deploying Neo4j and allows users to take advantage of its scalability features without requiring custom scheduling. The release of Neo4j 3.1 introduced a new clustering infrastructure called Causal Clustering, which consists of core servers accepting quorum writes via a consensus commit protocol and read replicas serving read requests. DC/OS provides the necessary tools for deploying and managing Neo4j clusters, including Marathon's Resource Configuration, persistent data storage, and access to the database from outside the cluster using an HTTP proxy. The setup process involves installing a DC/OS environment, launching the Neo4j services either through the Universe UI or CLI, scaling the cluster, and deploying example applications such as a Twitter-like setup.
