apache_beam.transforms.sideinputs module

For internal use only; no backwards-compatibility guarantees.

Important: this module is an implementation detail and should not be used directly by pipeline writers. Instead, users should use the helper methods AsSingleton, AsIter, AsList and AsDict in apache_beam.pvalue.
