 output from a simulation or observational dataset that you would like to stitch
 together into a zarr store.  If you have a way of combining those files lazily —
 i.e. opening them into dask-backed arrays — into a single dataset with maybe

 contiguous group of dask "chunks." I.e. it can correspond to one or more chunks
 across any number of dimensions.  A key detail is no partition straddles any
 dask chunks; this makes writing from independent processes completely safe.
