Hi, devs, I'd like to start a discussion about FLIP-266: Simplify network memory configurations for TaskManager[1].
When using Flink, users may encounter the following issues that affect usability. 1. The job may fail with an "Insufficient number of network buffers" exception. 2. Flink network memory size adjustment is complex. When encountering these issues, users can solve some problems by adding or adjusting parameters. However, multiple memory config options should be changed. The config option adjustment requires understanding the detailed internal implementation, which is impractical for most users. To simplify network memory configurations for TaskManager and improve Flink usability, this FLIP proposed some optimization solutions for the issues. Looking forward to your feedback.
