Sorry for late response. I was trying to read a big geotif file as follows. import xarray as xr xds = xr.open_rasterio(geotif_file)

My task was to array indexing and to save output into disk.

columns = [8,9,7,100,1050,......, 9000] rows = [18,19,17,1100,1105,......, 9100]

data = xds.isel(x=xr.DataArray(columns), y=xr.DataArray(rows))

np.save('output.npy', data)

Unfortunately, the performance in terms of time requirement seems quite unsatisfactory.

When I saw docs on xr.open_rasterio(), it mentions it is an experimental now. So, I'm curious if it could be much faster when it becomes stable.

I look forward to see it as stable version. Thank you so much.
