Why Use Zarr? Storing and Accessing Large NumPy Arrays with mmap and Zarr

Zarr provides a modern, chunked and compressed storage format that lets you treat massive NumPy arrays like in‑memory objects, offering on‑demand loading, flexible back‑ends (disk, S3, zip), automatic caching, resizing, parallel reads/writes, and superior performance compared to traditional mmap‑based memmap files.
