> When a DN has received a block, it immediately sends a block receipt IBR RPC to NN for
reporting the block.  Even if a DN has received multiple blocks at the same time, it still
sends multiple RPCs.  It does not scale well since NN has to process a huge number of RPCs
when many DNs receiving many blocks at the same time.
