             Summary: FLIP-266: Simplify network memory configurations for TaskManager
                 Key: FLINK-30469
                 URL: https://issues.apache.org/jira/browse/FLINK-30469
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Network
    Affects Versions: 1.17.0
            Reporter: Yuxin Tan


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 resolve the issues, we propose some improvement solutions. For more details see [FLIP-266|[https://cwiki.apache.org/confluence/display/FLINK/FLIP-266%3A+Simplify+network+memory+configurations+for+TaskManager].]
