Dian Fu created FLINK-15875: ------------------------------- 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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
