Udi Meiri created BEAM-9489: ------------------------------- Summary: python typehints: reduce the number of runtime-type-check wrappers Key: BEAM-9489 URL: https://issues.apache.org/jira/browse/BEAM-9489 Project: Beam Issue Type: Bug Components: sdk-py-core Reporter: Udi Meiri
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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
