In the oplog instructions, is "local" a placeholder?


#1

I’m looking at https://github.com/meteor/meteor/wiki/Oplog-Observe-Driver, and several times “local” is mentioned. Is this a database called “local”, or a placeholder for whatever your app’s database is called? I.e.:

MONGO_OPLOG_URL=mongodb://oplogger:PasswordForOplogger@mongo-server-1.example.com,mongo-server-2.example.com,mongo-server-3.example.com/local?authSource=admin

Is “local” supposed to be my app’s database name?

If so, I wonder if it might be renamed to “meteor” or “app” since the page is discussing replica sets, where a given database named “local” might reasonably exist for some reason. :slight_smile: Or perhaps I’m the only one who has been confused by this? I’ve been using “local” in all my provisioning scripts, but as I prepare to go to production I wonder if I’ve been doing it wrong.

Thanks.

No, local is a special mongo db managed by internals
