Hi [~maoling], do you mean this
[backPressureHosts|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/service/StorageProxy.java#L1486]
?
IIf I'm right, I think it is better to provide some test data to prove that
this modification can really improve performance.
EDIT :
In my mind ,the backPressureHosts list is never used, but as the replica
nodes number can not be big (usually 3 or 5 ), so I want to know how to
improve the performance.
