   > > Introduce a new configuration rss.server.hdfs.speed. We record the 
timestamp which the partition start to receive data. And then we record the 
timestamp which the partition start to flush data. We can use two timestamps to 
calcuate partition receive data speed. We use (partition receive data speed / 
HDFS write speed) to calculate how many threads which we need to write HDFS 
data. We use the number to create HDFS writer.

   > It looks too complex, the initial goal is to solve the single partition 
lock problem. Does above solution will solve this?
   
   Yes, we don't need to adjust the parameter by hand.
