----------------------------------
[~szetszwo] Hi, sorry, I have one question.
When HDFS write data, does datanode need to copy data between off-heap and
on-heap ? Because ratis-streaming did not need to copy data between off-heap
and on-heap, maybe ratis-streaming have a better write performance than HDFS ?
