First of all I want to thank the developers for this amazing project :) Here's my question Imagine I have 100 users. Each has its own unique id. Let one user reserves table at specific time (basically writes to database) now when database is updated all of my users is notified and onDataAdded method is called. Is it possible to call onDataAdded method to only client that has updated database?

Thanks!

This is pretty much a general Meteor question, and not a question related to this library.

But anyway, the important idea is that your subscriptions and publications control which client gets to see certain pieces of information.

If you don't want everybody to receive the new information, you just push it to a publication that only the specific user will (and can) subscribe to, e.g. a publication of notifications that expects the user's ID as a parameter.

If you publish data to a place that all users subscribe to, on the other hand, you will send this update to all users, of course.
