they will ensure that the computation is dispatched to the appropriate
backend. You can find them in the xarray.ufuncs module:

Default, pandas-backed indexes built-in Xarray:
indexes.PandasIndex indexes.PandasMultiIndex
These backends provide a low-level interface for lazily loading data from
external file-formats or protocols, and can be manually invoked to create
arguments for the load_store and dump_to_store Dataset methods:
