> 1.met same problem about this:
> https://issues.apache.org/jira/browse/CASSANDRA-9549
> I confuse about that this was fixed in release 3.3 according this page:
> https://github.com/apache/cassandra/blob/trunk/CHANGES.txt
> so I change to 3.4,and also have  found this problem again 
> I think this fix should be included in 3.3.3.4
> can you explain about this?
> 2.our write rate exceed the value that our cassandra env can support,
> but i think it should descrese the write rate,or block.consumer the writed data,keep
the memory down,then go on writing,not cause out-of-memory instead.
