ArangoDB 3.3 Beta Release – New Features and Enhancements
It is all about improving replication. ArangoDB 3.3 comes with two new exciting features: data-center to data-center replication for clusters and a much improved active-passive mode for single-servers. ArangoDB 3.3 focuses on replications and improvements in this area and provides a much better user-experience when setting up a resilient single-servers with automatic failover.
This beta release is feature complete and contains stability improvements with regards to the recent milestone 1 and 2 of ArangoDB 3.3. However, it is not meant for production use, yet. We will provide ArangoDB 3.3 GA after extensive internal and external testing of this beta release.
Data-Center to Data-Center Replication
Disaster can strike anytime, therefore companies need to be prepared. While a failure of a single machine in a cluster can easily be tolerated, the loss of a complete data-center is a major disaster. In this case, a backup data-center can take over the workload of the failed on, therefore ensuring operations with only minimal downtime. The data-center to data-center replication is described in more detail in this article.
Active-Passive Single-Server
You might not always need the full power of a cluster setup. Quite often a single-server is enough to handle the workload. However, such a setup creates a single point of failure. In order to avoid this, you can create an active-passive pair of two single-servers with automatic failover. Read more about this feature here.
It would be a great help if you could give it a test, and let us know your feedback on ArangoDB Community Slack.

The new part is that it also works with the new mechanic of acquiring the known coordinators in the cluster. In addition, the fallback for hosts not only works for coordinators in a cluster setup but also for ArangoDBs new feature “active-passive single server” which is introduced with ArangoDB 3.3 Beta Release.
