Zarr
Zarr is a chunked, compressed array storage format designed for scalable analysis of large multidimensional datasets, especially in cloud and parallel workflows.
Why it matters
Zarr matters because storage layout becomes part of the performance story. Chunking, compression, and cloud-friendly access patterns can decide whether a dataset feels interactive or painful.
Where it fits
It is especially relevant in modern geoscience and Earth-system computing where high-dimensional arrays need lazy access, parallel processing, and distribution-friendly storage.
