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.

Sync Schema (DDL) Changes

Written by Eric Long

Replicating the database schema on remote nodes and syncing schema changes to them when tables are altered is possible with SymmetricDS using a couple of simple techniques. First, tables can be created and populated as an initial load of data when the node is registered. Second, table definitions can be sent to nodes as needed to create or alter tables using the data definition language (DDL) of the database.
