What is SymmetricDS

SymmetricDS is open source software for multi-master database replication, filtered synchronization, or transformation across the network in a heterogeneous environment. It supports multiple subscribers with one direction or bi-directional asynchronous data replication. It uses web and database technologies to replicate tables between relational databases, in near real time if desired. The software was designed to scale for a large number of databases, work across low-bandwidth connections, and withstand periods of network outage.
