zarr-store-2/
zarr-file-store-3

but raise `NotImplementedError` for

I don't know whether it would be easy to detect the `glob` pattern for the second example in all cases though.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,606683601

For e.g. `xr.open_dataset(..., format=""zarr"")`. 

This would then delegate to `open_zarr` or a new `open_netcdf` or `open_rasterio` as appropriate. Then `open_mfdataset` would just work for all these formats without requiring duplicate code.
