Let me try to explain my problem.
I have resource heavy helper which I should run on page as rare as possible.
The helper contains a reactive variable:
When I update denormalized field
Meteor.user().statsCache.hits, not touching
Meteor.user().profile.gender my helper reactively updates without any need, lagging UI. I understand it is because subscription updates and sends a new User document to client.
But how can I prevent helper to rerun if its particular reactive document parameter doesn’t change?
I thought about somehow splitting it to 2 different subscriptions, but I’m not sure if this helps as server may still push change?
So any solutions would be appreciated.
