----------------------------------
> 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
> 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.
