> Key: FLINK-15875
> URL: https://issues.apache.org/jira/browse/FLINK-15875
> Project: Flink
> Issue Type: Improvement
> Components: API / Python
> Reporter: Dian Fu
> Assignee: Dian Fu
> Priority: Major
> Fix For: 1.11.0
>
>
> Currently PyFlink depends on Beam's portability framework for Python UDF
> execution. The current dependent version is 2.15.0. We should bump it to
> 2.19.0(the latest version) as it includes several critical features/fixes,
> e.g.
> 1) BEAM-7951: It allows to not serialize the window/timestamp/pane info
> between the Java operator and the Python worker which could definitely
> improve the performance a lot
> 2) BEAM-8935: It allows to fail fast if the Python worker start up failed.
> Currently it takes 2 minutes to detect the failure if the Python worker is
> started failed.
> 3) BEAM-7948: It supports periodically flush the data between the Java
> operator and the Python worker. This feature is especially useful for
> streaming jobs and could improve the latency.
