Dynamically create collection with Mongoose

Question

I want to give users the ability to create collections in my Node app. I have really only seen example of hard coding in collections with mongoose. Anyone know if its poss

Answer 1

Say I have 20 different events. Each event has 1 million entries... As such if this is all in one collection I will have to filter the collection by event for every CRUD op.

I would suggest you keep all events in the same collection, especially if event names depend on client code and are thus subject to change. Instead, index the name and user reference.

mongoose.Schema({
  name: { type: String, index: true },
  user: { type: mongoose.Schema.Types.ObjectId, ref: 'User', index: true } 
});

Furthermore I think you came at the problem a bit backwards (but I might be mistaken). Are you finding events within the context of a user, or finding users within the context of an event name? I have a feeling it's the former, and you should be partitioning on user reference, not the event name in the first place.

If you do not need to find all events for a user and just need to deal with user and event name together you could go with a compound index:

schema.index({ user: 1, name: 1 });

If you are dealing with millions of documents, make sure to turn off auto index:

schema.set('autoIndex', false);
