Feature Request: Parquet File Support

[tgruben]

Any hope of getting Parquet file support anytime soon or is CSV going to remain the format of choice

I'm guessing that Apache Arrow implements Parquet, and the etable.Tensor is Arrow compatible, so in principle this could be easy.. :)

hmm, it appears etensor.Tensor doesn't fully implement arrow's tensor.Interface. Missing Retain() and Release() i think.

@tgruben that link is taking ages to load. Here is the direct code link

@tgruben and @rcoreilly

Its might make sense to use DataFusions as the Data store backing all this. That means that S3 is the backing store.
