Or with a context manager, e.g.,
```python
for num in range(100):
    with xr.open_dataset('data.{}.nc'.format(num)) as ds:
        # do some stuff, but NOT assigning any data in ds to new variables
        ...

It's a bit of a short in the dark, but that might help here.

Memory growth with `xr.open_dataset('data.nc', chunks=None)` is expected, because by default we set `cache=True` when not using dask. This means that variables get cached in memory as NumPy arrays.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,326533369
