That depends on the backend. Each datastore in a sync config invokes the
backend, which then picks an actual database based on the "database"
parameter configured for the datastore.

Usually, that parameter is empty, which typically means "pick the
default". But that's entirely up to the backend. See
EvolutionSyncSource::findSource() for an example how that is done in
EDS.

No, your backend would only access one.

That confirms my theory: I bet your register_func object linked into
both shared modules, and then each module registers both kinds of data.

You need two registration files, one per module, and only register data
provided by that module in the file.
