What's the difference between a node and an engine in SymmetricDS?

https://www.symmetricds.org/doc/3.8/html/user-guide.html says

Multiple nodes can be hosted in a single SymmetricDS instance.
SymmetricDS will start a node for each properties file it finds
in the engines directory.

Each .properties file specifies an engine.name and an external.id. They are described as follows

  • engine.name: This is the engine name. This should be set if you have more than one engine running in the same JVM
  • external.id: The external id is usually used as all or part of the node id.

Based on this I would guess there is a 1-1 mapping between nodes and engines. Is this correct? Are nodes and engines kind of the same thing?

Solution

  • Yes, that's correct. The mapping is 1-1
