255897797 MDU6SXNzdWUyNTU4OTc3OTc= 1559 Subsetting not reducing memory consumption with mfdataset on Windows 761677 closed 0     5 2017-09-07T10:58:30Z 2017-09-14T09:51:51Z 2017-09-14T09:51:51Z NONE      

On Windows, with the following code I run out of memory: d = xr.open_mfdataset(filepath) sed = d.sediment_mass_per_unit_area.isel(time=-1) sed.load() d.close() but when using "open_dataset" I load the data instantly: d = xr.open_dataset(filepath) sed = d.sediment_mass_per_unit_area.isel(time=-1) sed.load() d.close() On linux both methods use minimal memory. The target file is 1.5 GB, and the target variable is 1460x862x900 floats. Filepath is a single file, not multiple files. Xarray 0.9.6 used on both systems, installed with conda.
