> I found that kafka is not on the server side, limiting the amount of data
> read per fetch request. This may cause the kafka server program to report an
> error: OutOfMemory. Due to unreasonable client configuration,
> fetch.message.max.bytes configuration is too large, such as 100M, because the
> kafka server receives a lot of fetch requests at a certain moment, causing
> the server to report an error: OutOfMemory。So I think this is a bug。
