> Today hdfs audit log/hive query log events are partitioned by user field and pass all the way from source to spouts, bolts
> But due to the existence of heavy user, the load of spout/bolt are skewed, especially for alert executors which may be computing/memory intensive
> We need to resolve this by dynamic partition events based on spout/bolt capacity
