The datacenter to datacenter replication setup in ArangoDB has a few limitations. Some of these limitations may be removed in later versions of ArangoDB:
All the machines where the ArangoDB Server processes run must run the Linux operating system using the AMD64 architecture. Clients can run from any platform.
All the machines where the ArangoSync Server processes run must run the Linux operating system using the AMD64 architecture. The ArangoSync command line tools is available for Linux, Windows & MacOS.
The entire cluster is replicated. It is not possible to exclude specific databases or collections from replication.
