Zarr: Chunked, Compressed N-dimensional Arrays

Zarr is a Python package that provides an implementation of chunked, compressed, N-dimensional arrays. It is designed for efficient use in parallel computing and supports various storage backends, including local disk, cloud object stores (like S3), and in-memory stores. The library is actively maintained, with its current version being 3.1.6, and recently underwent a significant refactor with the release of version 3, which introduced support for the Zarr v3 specification and improved performance.
