> In ZooKeeper mode, large config values can be created by appending. In contrast, KRaft mode does not allow this. The root cause is that {{ConfigRecord}} assumes a maximum value size of {{{}Short.MAX_VALUE{}}}. This causes a runtime error, which is then converted to "UnknownServerException" for users, making the issue unclear.
