ReactiveMongo automatically writing to Primary node

[Sid Feiner]

Hey,

In my application, I connect only to a replica node but I've noticed that when i use insert/update commands, they work as well. Does ReactiveMongo automatically finds the primary node and sends the inserts/updates to that node?

I'm used to working with Mongo from python scripts and with PyMongo, it doesn't do that by default and I get an error saying that I can't insert/update on a secondary node.

As any MongoDB driver, it uses ReadPreference and WriteConcern: http://reactivemongo.org/releases/0.1x/documentation/tutorial/connect-database.html
