>                 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
>            Assignee: Yuxin Tan
>            Priority: Major
>
> 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].
> This is the umbrella ticket to track all the changes of this feature.
