Question

Answer 1

pyTables is the Python interface to HDF5 data model and is pretty popular choice for and well-integrated with NumPy and SciPy. pyTables will let you access slices of databased arrays without needing to load the entire array back into memory.

I don't have any specific experience with sparse matrices per se and a quick Google search neither confirmed nor denied that sparse matrices are supported.
