Common batch mode was enhanced in SymmetricDS 3.11 to allow any group of nodes to share batches. Let's look at what common batches are and why this is a big deal for database replication with more than a couple nodes.

For most of our large clients where SymmetricDS is playing a mission critical role in their organization, our customers take advantage of SymmetricDS Pro's out of the box capabilities to be load balanced. While SymmetricDS does a great job with hands off recovery in cases of hardware or infrastructure failure, most clients want as little downtime as possible. They simply don't want a single point of failure in their synchronization scenario. The good news is, with SymmetricDS Pro, load balancing is simple and straight forward.

Load testing of database replication finds the upper limit of how well the system can perform, and it provides assurance that replication will make it through times of peak usage. Let's look at how to simulate production activity for SymmetricDS data replication in a lower environment so you can deploy with confidence.

SymmetricDS 2.2.0 is a minor release that brings 15 bug fixes, 8 improvements, and 5 new features.  Some highlights include:

• The incoming data loader was changed to use a single connection to eliminate contention with a nested transaction and reduce the connection pool requirements. 
• The purge job that cleans up the runtime tables is now three separate jobs that can be scheduled independently.
• A new query plan is being used to route and batch data changes that is more efficient.

This release also includes a new project organization and reduced library dependencies in preparation for small footprint clients.  We've created a new Mobile Development forum to discuss plans for an upcoming mobile implementation.
