Wrapping a `kerchunk.Array` object directly with xarray about xarray HOT 3 OPEN

One issue that came up around not being able to avoid creating indexes for 1D coordinates (@benbovy): #8107 (comment)

from xarray.

Another one is why does opening a dataset require indexing into it?

If I add a print(indexer) inside Variable.__getitem__ here

In [3]: xr.tutorial.open_dataset('air_temperature')
Out[3]: BasicIndexer((slice(None, 13, None),))
BasicIndexer((slice(-12, None, None),))
BasicIndexer((slice(None, 14, None),))
BasicIndexer((slice(-13, None, None),))
BasicIndexer((slice(None, 12, None),))
BasicIndexer((slice(-11, None, None),))

why is any of that indexing happening?

EDIT: Oh it's happening when the ds gets printed...

EDIT2: False alarm about this one 😅

from xarray.

It's interesting to define a minimal ConcatenatableArray and see what is required to get that to work inside xarray. Again we get problems with indexes being built unexpectedly.
