c# driver and best practices/patterns for mongo access

[mrdiesel]

I want to use mongodb for a project.

OK yes, i able to connect to it and do things.

However, I want to be able to wrap the mongodb driver around a wrapper
so if i want to change the database, i want to be easily change it.

Repository pattern looks like something I can use with Mongodb, but I
m kinda over thinking where to start the connection? should i use a
singleton ?

Mongodb docs says that it is thread safe, so if i create a single
MongoServer and single MongoDatabase classes via Singleton and per
collection, I can have a method that return a collections.

Is this a bad design?

What would be a better design?

I want to use singleton to create connection to database cause I dont
want to keep creating connection per thread, if there is already a
persistent connection.

any experience with this?

It's OK to create a singleton in your code to hold a single reference to an instance of MongoServer (or even MongoDatabase or MongoCollection).

Note that as the documentation states whenever you call MongoServer.Create with the same connection string you get the SAME instance of MongoServer back, so it is not strictly necessary for you to create a singleton reference in your code.

Having a singleton reference in your code would be minutely faster, only because it eliminates a couple of dictionary lookups that MongoServer.Create does to check whether an instance of MongoServer already exists for that connection string.

I don't mind. It just gets confusing when there are two parallel threads going on... :)

Did you get all your questions answered?
