I would like to use Meteor (Node.JS) to develop an application that will be used by 3,000+ concurrent users on a large size database. I have looked at the nice examples and the idea to push changed data to the clients is very nice and very useful, but before I start the development I want to be sure how it works behind the scenes to be sure that when I have the application running with all these users it work fast with standard hardware. I also require this to use Oracle as a database, but not sure that it is supported and if not, what are the requirements from an Oracle package to enable this facility.
I think that the server is having an active on going non-blocking query on the OPLOG table in mongodb and that is how we get the callback for all the changes in the database. Is that correct ? if so, is there a similar way to do it in Oracle ?
Thanks Roni.

Nope, meteor is currently mongo-only as they have implemented an in-browser library called minimongo. My guess is this project will never support oracle, but who knows. There is no mention of oracle support on the meteor project roadmap
Just happened to come across this question while searching at google.
However, if there are no native solutions. We can always figure out a way for a medium language to issue publishing.
Example Case:
Python will be used for synchronising data between Mongodb and Oracle (24/7 operation using cx_Oracle and MongoDB drivers from python)
Meteor Server will keep watch on what to publish Meteor clients/browsers that subscribed to the channel that will be updated with oracle data.
