# xarray.backends.NetCDF4DataStore.load

`NetCDF4DataStore.``load`()

  This loads the variables and attributes simultaneously. A centralized loading function makes it easier to create data stores that do automatic encoding/decoding.

  For example:

      class SuffixAppendingDataStore(AbstractDataStore):

          def load(self):
              variables, attributes = AbstractDataStore.load(self)
              variables = {'%s_suffix' % k: v
                           for k, v in variables.items()}
              attributes = {'%s_suffix' % k: v
                            for k, v in attributes.items()}
              return variables, attributes

  This function will be called anytime variables or attributes are requested, so care should be taken to make sure its fast.
