221387277 MDU6SXNzdWUyMjEzODcyNzc= 1372 decode_cf() loads chunked arrays 4992424 closed 0     7 2017-04-12T20:52:48Z 2018-04-12T23:38:02Z 2018-04-12T23:38:02Z NONE      

Currently using xarray version 0.9.2 and dask version 0.14.0.

Suppose you load a NetCDF file with the chunks parameter:

python ds = xr.open_dataset("my_data.nc", decode_cf=False, chunks={'lon': 10, 'lat': 10})

The data is loaded as dask arrays, as expected. But if we then manually call xarray.decode_cf(), it'll eagerly load the data. Is this the expected behavior, or should decode_cf() preserve the laziness of the data?
