SymmetricDS is web-enabled, database independent, data synchronization/replication software. It uses web and database technologies to replicate tables between relational databases in near real time. The software was designed to scale for a large number of databases, work across low-bandwidth connections, and withstand periods of network outage.
You may know about the MySQL Cluster, which is a complex architecture to achieve high availability and performance. One of the advantages of MySQL Cluster is that each node is a peer to the others, whereas in a normal replicating system you have a master
Fast Replication With Low Network Demand LifeKeeper Data Replication replicates data at the block level, below the file system. Most importantly, LifeKeeper Data Replication only replicates changes in data and thereby minimizes the demand on systems and n
