Subject [GitHub] flink issue #4594: [FLINK-7517][network] let NettyBufferPool extend PooledBy...

Github user NicoK commented on the issue:

    Yes @zhijiangW, I kept the original logic.
    I guess, the reasoning behind using off-heap netty buffers only was to reduce the overhead
before transmitting messages over the wire: 1) we reduce GC overhead somewhat and 2) at some
point we need the memory to be off-heap and put into kernel space anyway - depending on netty,
this may be optimised if it is already off-heap.
    Also, starting with #4481 we will only be using off-heap network buffers anyway.
