Summary: Support to start up Python worker in process mode
Key: FLINK-14017
URL: https://issues.apache.org/jira/browse/FLINK-14017
Project: Flink
Issue Type: Sub-task
Components: API / Python
Reporter: Dian Fu
Fix For: 1.10.0
We employ Apache Beam's portability frameowork for the Python UDF execution.
However, there is only a golang implementation for the boot script to start up
SDK harness in Beam. It’s used by both the Python SDK harness and the Go SDK
harness. This is not a problem for Beam. However, it’s indeed a problem for
Flink as it indicates that the whole stack of Beam’s Go SDK harness will be
depended if we use the golang implementation of the boot script. We want to
avoid this by adding a Python boot script.
