SymmetricDS

SymmetricDS is a Java-based platform for database replication and file synchronization that is platform-independent, web-enabled, and database-agnostic. It is designed to synchronize data across distributed, heterogeneous database environments asynchronously. It handles real-world challenges like conflict resolution, bandwidth constraints, intermittent connectivity, and firewalls — making it reliable for distributed, heterogeneous environments. The platform scales horizontally to handle massive data volumes and hundreds of nodes, even with bi-directional replication. While the open-source edition provides the robust foundation, the SymmetricDS Pro edition extends it with capabilities that address enterprise operational, performance, security and compliance demands.
