Yuxin Tan updated FLINK-30469:
------------------------------
Description:
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
