Limit MongoDB database size?

Question

We're interested in deploying MongoDB, but we need to know if we can limit database/table sizes?

For example:

db.user1.find() db.user2.find()

As you can see from the above, each user will have their own database. We want to limit each user's database so we don't have any one user eating up all our hard drive space.

Is this possible with MongoDB?

Thanks.

Answer 1

You can create a database per user and enable the --quota option. This will allow you keep any user from using too much space.

Answer 2

Try to

db.createCollection("mycoll", {size:100000})
