We have some thoughts about how the new invalidation system will make offline a lot more feasible. In pub&#x2F;sub based Meteor apps you would need to reload all of the data if you took too long to reconnect, in the new system you will hopefully be able to get just the diff after a much longer reconnect gap, or possible indefinitely depending on implementation details. This is because the app server doesn&#x27;t need a copy of all of the client&#x27;s data anymore.
