What is SymmetricDS

SymmetricDS is open source software for both file and database synchronization with support for multi-master replication, filtered synchronization, and 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 data as a scheduled or near real-time operation. The software was designed to scale for a large number of nodes, work across low-bandwidth connections, and withstand periods of network outage. It works with most operating systems, file systems, and databases, including Oracle, MySQL, MariaDB, PostgreSQL, MS SQL Server (including Azure), IBM DB2, H2, HSQLDB, Derby, Firebird, Interbase, Informix, Greenplum, SQLite (including Android), Sybase ASE, and Sybase ASA (SQL Anywhere) databases.

SymmetricDS 是一款用作文件和数据库同步的开源软件，支持多主机复制、同步过滤及支持多种网络环境的传输。它支持多个订阅者从一个方向或双向异步数据复制。使用了网站和数据库技术来制定复制计划和近实时的操作。该软件设计上考虑了大量节点、低网络带宽的情况，可承受网络中断的异常情况。可以工作在大部分操作系统、文件系统及数据库上，包括Oracle，MySQL，MariaDB，PostgreSQL，MSSQL（包括Azure），IBM DB2，H2，HSQLDB，Derby，Firebird，Interbase，Infomix，Greenplum，SQLite（包括Android），Sybase ASE及Sybase ASA（SQL Anywhere）。
