> Currently, the {{NetworkBufferPool}} always uses off-heap memory to reduce memory copy from flink {{Buffer}} to netty internal {{ByteBuf}} during transporting on sender side.
>
> But for {{SpillReadBufferPool}} in {{SpilledSubpartitionView}}, it still uses heap memory for caching. We can make it as off-heap by default similar with {{NetworkBufferPool}} or decide the type by the current parameter {{taskmanager.memory.off-heap.}}
