| 689390592 | MDU6SXNzdWU2ODkzOTA1OTI= | 4394 | Is it possible to append_dim to netcdf stores | 90008 | closed | 0 | 2 | 2020-08-31T18:02:46Z | 2020-08-31T22:11:10Z | 2020-08-31T22:11:09Z | CONTRIBUTOR | Is your feature request related to a problem? Please describe. Feature request: It seems that it should be possible to append to netcdf4 stores along the unlimited dimensions. Is there an example of this? Describe the solution you'd like I would like the following code to be valid: ```python from xarray.tests.test_dataset import create_append_test_data ds, ds_to_append, ds_with_new_var = create_append_test_data() filename = 'test_dataset.nc' Choose any one ofengine : {'netcdf4', 'scipy', 'h5netcdf'}engine = 'netcdf4' ds.to_netcdf(filename, mode='w', unlimited_dims=['time'], engine=engine) ds_to_append.to_netcdf(filename, mode='a', unlimited_dims=['time'], engine=engine) ``` Describe alternatives you've considered I guess you could use zarr, but the fact that it creates multiple files is a problem. Additional context xarray version: 0.16.0 |
