I have decided to do a Monthly webinar series showcasing some of the development & hacks at MeteorHacks. We had our first webinar yesterday and it was a success with over 50 live attendees. I mainly talked about FastRender and Subscription Optimization. Live Record and slides of the webinar will be available within this week.
Oplog integration is the meteor’s main approach for scaling at the moment. But in this case, we are backed by a single MongoDB server. (okay, we can do sharding). But there is a new approach for scaling discussed in the meteor-core mailing list. With that, you could be able to connect to a different DDP servers depending on the some logic in the client side. There is much work needs to be done, but preliminary work has been implemented.
