> Currently, for sort blocking shuffle, the corresponding data reader always
> allocate a fixed size of 8M buffers for shuffle data reading. FLINK-28373 can
> increase buffer utilization, after which, we can reduce the buffer size per
> request to reduce the time waiting for buffers. (This change is guarded by
> TPC-DS test that there is no performance regression)
