Description

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。
