@shoyer, if if we are happy to open all netCDF files and read out the metadata from a master process that would imply that we would open a file, read the metadata, and then close it, correct?

Array access should then follow something like the @mrocklin's netcdf_Dataset approach, right?

Yes, this is correct.

In principle, if we have a very large number of files containing many variables each, we might want to do the read in parallel using futures, and then use something like futures_to_dask_arrays to bring them together. That seems much trickier to integrate into our current backend approach.
