I think the lengths for the corresponding fields can be seen clearly in the
below write method.

> URL: https://issues.apache.org/jira/browse/FLINK-7406
> Project: Flink
> Issue Type: Sub-task

> Reporter: zhijiang

>
> This is a part of work for credit-based network flow control.
> Currently {{PartitionRequestClientHandler}} receives and reads
> {{BufferResponse}} from producer. It will request buffer from {{BufferPool}}
> for holding the message. If not got, the message is staged temporarily and
> {{autoread}} for channel is set false.
> For credit-based mode, {{PartitionRequestClientHandler}} can always get
> buffer from {{RemoteInputChannel}} for reading messages from producer.
> The related works are:
> * Add the backlog of producer in {{BufferResponse}} message structure
> * {{PartitionRequestClientHandler}} requests buffer from
> {{RemoteInputChannel}} directly
> * {{PartitionRequestClientHandler}} updates backlog for
> {{RemoteInputChannel}}, and it may trigger requests of floating buffers from
> {{BufferPool}}
