AutoML() doesn't seem to use Ray's object store (for large datasets)

Hi there,

I have a large dataset (+100GB) that I have been trying to make FLAML (AutoML) work with, no success so far. Since FLAML uses Ray, shouldn't it take advantage of Ray's object store (object spill to disk)?
If not, any suggestions on how we should go about out-of-memory compute with FLAML?
