Top 3 Reasons to Use SymmetricDS

Cross Platform

SymmetricDS can run on most platforms, from servers to laptops to mobile devices, and replicate from any database to any database, whether they are located on-premise, across a wide area network, or in the cloud. Based on the Java runtime, SymmetricDS can run on most operating systems, including Windows, Linux, Unix, Mac OS X, Android, and many others. For mobile devices like iOS and embedded systems, a minimal C-based client can handle the same core replication protocol.

SymmetricDS can replicate different databases together, so you can run SQLite on your mobile device, MySQL on the back office, and Oracle at the central office, all of them syncing data with each other. With support for most major database platforms, you can choose a database that is best suited to the application, and seamlessly integrate into a heterogeneous enterprise. Avoid vendor lock and gain the freedom of database independence.

Scale Out Performance

From two databases to several thousand databases, SymmetricDS is optimized to replicate data quickly and handle a large number of synchronization requests. By using web server technology, many simultaneous requests from remote databases can be handled to sync data to a central deployment. A multi-threaded architecture is key to maximum performance of replication. By assigning tables to channels, data can flow using separate threads to load data in parallel. Each channel uses separate threads for extract, transfer, and loading of data.

To handle more clients and improve availability of a central database, clustering allows for multiple instances of SymmetricDS to connect to the same database. Large networks of databases can be grouped into tiers for more control and efficiency, with each group syncing data to the next tier in an efficient multi-tier architecture.

Flexible Configuration

A powerful set of features for data replication give you flexibility to meet project requirements. Synchronize data across nodes on remote networks with low bandwidth usage and automatically handle periods of disconnected operation.

With asynchronous replication in the background and an efficient communication protocol, SymmetricDS guarantees replication by tracking batch data through automatic recovery and retry attempts. Data can be synchronized in one direction or both directions in a multi-master configuration.

You configure the nodes, groups, and how network connections are established. Push data at a short interval for real time integration or pull data periodically to work through firewalls and reduce connection overhead.
