Rechunker

Rechunker is a Python package designed for efficient and scalable manipulation of the chunk structure of chunked array formats, such as Zarr and TileDB. It takes an input array (or group of arrays) from persistent storage and writes out a new array with the same data but a different chunking scheme, often utilizing an intermediate temporary store. It is currently at version 0.5.4 and is actively maintained by the Pangeo community, with regular releases addressing compatibility and bug fixes.
