Hey @viper-kun,
I played around with this optimization myself at one point. If I remember
correctly, I think that you might have to update other parts of the code to
account for the fact that empty partitions' files will now be missing instead
of empty.
Do you have performance benchmarking results that motivated this change?
Just curious to know how much of a speedup / benefit this gives.
