Improved hop checkpoint compilation (awareness of local mem)
Improved hop checkpoint compilation (awareness of local mem)

So far the compilation of checkpoints was too conservative, i.e., we
often generated unnecessary checkpoints. Now this decision is made based
on the actual local memory budget which prevents unnecessary spark
context creation and hence improves performance for small use cases.
