I was hoping that canisters would simply have access to more memory through orthogonal persistence. Is there going to be some API that will be required? I think to be of the greatest benefit to developers, the heap of the canister needs to be greatly increased. You should be able to just create data structures and fill them with data, scaling up to the capacity of the subnet.
And in the future…I think it would be great to figure out a way to scale a single canister beyond the bounds of a subnet, but perhaps we can discuss that later.
