SymmetricDS is a data and file sync/replication solution. It is a platform-independent, web-enabled, and database-agnostic synchronization tool. SymmetricDS was built to replicate changes, bi-directionally, between remote nodes and a centralized node.

Features

  • Database Independent - Supports: Oracle, MySQL, PostgreSQL, Microsoft SQL Server, Microsoft Azure, HSQLDB, H2, Apache Derby, IBM DB2, Firebird, Informix, Greenplum
  • Transaction Aware - Data updates are recorded and replayed with the same atomicity
  • Guaranteed Delivery - Synchronized data is guaranteed to arrive at the target destination. If a synchronization fails, the same batch of data will be retried until it succeeds or manual intervention is taken. All other data synchronization is halted for the failed channel only.
  • Conflict Management - Data conflicts can be detected and resolved
  • Data Transformation - Data can be transformed to load into different structured tables
  • Data Channels - Table synchronizations are grouped into independent channels
  • Centralized Configuration - All configuration is downloaded from a central registration server
  • Data Filtering and Rerouting - Allows for localized passwords and sensitive data filtering/routing
  • HTTP Transport - Pluggable transport defaults to Representation State Transfer (REST-style) HTTP services
  • Initial Data Load - Prepare the satellite database with an initial or recovery load of data
  • Flexible Transport - Push (trickle-back data) or Pull (trickle-poll data) changes
  • Multiple Schemas - Supports multiple database schemas naturally through the existence of Data Channels
  • Simple Data Protocol - A fast streaming data format that is easy to generate, parse, and load
  • Bidirectional Synchronization - The same table can be synchronized both to and from the host system while avoiding update loops
  • Primary Key Updates - Captures the "before" and "after" data being changed, allowing updates to primary key data
  • Payload Compression - Optionally compresses data on transport
  • Extendable API - Add customizations through extensions and plug-in points
  • Auto Database Creation - Optionally allow creating and upgrading of database schema
  • Multiple Deployment Options - Standalone engine, web application, embedded software component
  • Embeddable - Small enough to embed or bootstrap within another application (i.e. a POS application)
  • Remote Management - Administration through a Java Management Extensions (JMX) console or REST
  • Remote Database Administration - SQL can be delivered and run at remote databases via the synchronization infrastructure
  • Database Versioning - Specify data synchronization by version of target database
  • Android Support - Independent client that works on Android
  • File Synchronization - Sync files as well as data
