Syncing between 2 local databases currently possible?

Hi,

Do you know if having 2 local databases (one sync'ed from Dropbox on the local filesystem and another 'reference' one also on the local filesystem) is a possible use-case for the CBLDatabase -push/pull API? Couldn't find out how to setup this with current API. Thank you!

There is some partial support between syncing two local databases, but they have to be known to CBL already, i.e. both in the app’s database-manager directory. If the database is someplace external, you’d need to copy it into that directory first.

Putting a database in a Dropbox is kind of a weird idea. I assume you’re doing it to try to sync between devices, but then why wouldn’t you just use CBL’s replicator to do that?

OK, interesting. I'm not too familiar with CBL concepts. Using CBL replicator means having a server hosting the database, right? Our scenario here was to not have any hosted database, but instead only local ones. Then a user on a device could decide to share an object list (a DB subset) with another user (send by mail, Dropbox, whatever), who makes some changes, and then send it back to the orignal user for merging. Does that make any sense with CBL? Thank you.

The replicator handles peer-to-peer. If you want two devices to sync with each other, you start a listener on (at least) one of them, then the other one starts a replication to its address/port. I think there’s some description of it on the wiki.

Thank you. The copy file to db-manager probably makes more sense here, but I'll review the other one (peer-to-peer) too.
