> Key: FLINK-28377
> URL: https://issues.apache.org/jira/browse/FLINK-28377
> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / Network
> Reporter: Yingjie Cao
> Priority: Major
> Fix For: 1.16.0
>
>
> Currently, for sort blocking shuffle, the corresponding data reader always
> allocate a fixed size of buffers for shuffle data reading even when there is
> no much data to read which will cause buffer waste. We can optimize this to
> allocate less number of reading buffers if there is no enough data.
