Does the to_zarr method suffice: http://xarray.pydata.org/en/latest/generated/xarray.Dataset.to_zarr.html#xarray.Dataset.to_zarr ?

Question: how would one build a zarr-xarray dataset?

With zarr you can open an array that contains no data, and use set-slice notation to fill in the values (which is what dask's store essentially does).

If I have some pre-known coordinates and bigger-than-memory data arrays, how would I go about getting the values into the zarr structure? If this can't be done directly with the xarray interface, is there a way to call zarr's open/create/zeros such that the corresponding array will appear as a variable when the same dataset is opened with xarray?
