> python typehints: reduce the number of runtime-type-check wrappers
> ------------------------------------------------------------------

> Key: BEAM-9489
> URL: https://issues.apache.org/jira/browse/BEAM-9489
> Project: Beam

>
> The --runtime_type_check flag is considered to be a performance penalty.
> One of the possible slowdowns is the wrapper around DoFn.process(), which
> adds an extra call to the wrapped process() method.
> Currently, there are 2 wrappers applied: OutputCheckWrapperDoFn and
> TypeCheckWrapperDoFn. These could be merged into one to possibly save on
> overhead.
