SymmetricDS is open source software for database and file synchronization with Multi-master replication, filtered synchronization, and transformation capabilities. [2] It is designed to scale for a large number of nodes, work across low-bandwidth connections, and withstand periods of network outage. [3]
Databases can be deployed on a distributed cluster of servers (called ‘nodes’) using multi-master replication. [ 6 ] [ 8 ] Some operations at the cluster level require a consensus of a majority of nodes; consensus is determined using an implementation of the Raft algorithm called Rachis. [ 6 ]
