I am interested to implement an arrow based persisted cache store and I have a few related questions:
1. Is it possible just to use Plasma for this goal? (My understanding is that it is not persistable) Else, what is the recommended way to do so? 2. Is feather the better file format for persistence to avoid re-transcoding hot chunks? 3. When Pandas load data from plasma/arrow, is it doubling the memory usage? (One for the arrow representation, one for pandas representation) -- Thanks, Mike
