每个查询的Mgo会话模式更改

I am initializing my master *mgo.Session mode value to mgo.Monotonic when I first create a MongoDB connection. I was wondering if anyone has seen any issues if we change the mode to say mgo.Strong for the copied session using masterSession.Copy()

The reason I am trying to do this is because there are times when I would prefer to read from the primary node to avoid any issues with replica set lag and there are cases where it's okay to rely on read from secondary or replica node.

Would love to know how developers out there handle this similar scenarios Thanks
