Icechunk

Icechunk is an open-source (Apache 2.0), transactional storage engine for tensor / ND-array data, designed for use on cloud object storage. It augments the Zarr core data model with features that enhance performance, collaboration, and safety in a multi-user cloud-computing context. The library is currently at version 2.0.1 and follows a versioning scheme where major versions align with the on-disk format, allowing for breaking API changes even in minor releases.
