Describe the solution you'd like

We have started using xarray objects as "schema" for initializing zarrs that will be written to using the region argument of to_zarr. For example,

output_schema.to_zarr(path, compute=False) for region in regions: output = func(input_data.isel(region)) output.to_zarr(path, region=region)

Currently, xarray's tools for computing the output_schema Dataset are a lacking since rechunking existing datasets can be slow. dask.array.zeros_like takes a chunks argument, can we add one here too?

Describe alternatives you've considered
