1 year ago Another project already doing something similar - https://github.com/mattbellis/hepfile Not sure how close hepfile's HDF5 schema is to HDTree's but I can play around with it and see.
Similar to the C++ API, there already exists a lower-level HDF5 API that will do the heavy lifting for us. h5py
My general plan would be to make the interface
uproot-like where browsing can be done without loading data into memory and then users can request certain trees/branches/groups of them to be loaded into a specific object in memory (dataframe, numpy, awkward, etc..)
