---------------------------------
Fix Version/s: (was: 1.16.0)
> FLIP-206: Support PyFlink Runtime Execution in Thread Mode
> ----------------------------------------------------------
>
> Key: FLINK-25718
> URL: https://issues.apache.org/jira/browse/FLINK-25718
> Project: Flink
> Issue Type: New Feature
> Components: API / Python
> Affects Versions: 1.15.0
> Reporter: Huang Xingbo
> Assignee: Huang Xingbo
> Priority: Major
>
> We have provided PyFlink Runtime framework to support Python user-defined
> functions since Flink 1.10. The PyFlink Runtime framework is called Process
> Mode, which depends on an inter-process communication architecture based on
> the Apache Beam Portability framework. Although starting a dedicated process
> to execute Python user-defined functions could have better resource
> isolation, it will bring greater resource and performance overhead.
> In order to overcome the resource and performance problems on Process Mode,
> we will propose a new execution mode which executes Python user-defined
> functions in the same thread instead of a separate process.
