-------------------------------
Summary: Bump Beam to 2.19.0
Key: FLINK-15875
URL: https://issues.apache.org/jira/browse/FLINK-15875
Project: Flink
Issue Type: Improvement
Components: API / Python
Reporter: Dian Fu
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
as it includes several critical features/fixes needed, 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 whether the Python worker is started
successfully.
3) BEAM-7948: It supports periodically flush the data between the Java operator
and the Python worker. This's especially useful for streaming jobs and could
improve the latency.
