We have received many inquiries about the architecture of SymmetricDS lately. I think the user’s guide does a nice job of laying out how to implement and configure SymmetricDS, but we have noticed (after taking a step back) that it doesn’t provide a concise, technical overview. You can probably piece everything together from the guide, but it is probably worth some effort to describe how SymmetricDS works under the covers. We’ll be updating the documentation with this information in the near future.
