Subsetting data during replication can improve the overall performance of your sync scenario and reduce the size of target databases.   This article will explain some of the ways SymmetricDS will allow you to subset your data and how to consider the performance implications with each case.

SymmetricDS was originally designed to support a use case with numerous client nodes spread out geographically in order to replicate to a centralized server.  The out of the box properties and configuration are optimized to support many other use cases and may not be sufficient when you need more than a couple dozen client nodes.   Check out some of the helpful hints below to assist in a successful synchronization rollout to numerous clients.
