What is Python-Blosc2?
Python-Blosc2 is a high-performance compressed ndarray library with a flexible compute engine, using C-Blosc2 as its compression backend. It allows complex calculations on compressed data, whether stored in memory, on disk, or over the network (e.g., via Caterva2). It uses the C-Blosc2 simple and open format for storing compressed data.
