 `arrival_rate_secs` is an estimation of the number of tuples that are inserted 
into the queue in one second, although it is actually the dequeue rate.
 The `sojourn_time_ms` is calculated from the arrival rate and is an estimate 
of how many milliseconds each tuple sits in the queue before it is processed.
 
-The queue has a set maximum number of entries.  If the regular queue fills up 
an overflow queue takes over.  The number of tuple batches stored in this 
overflow section are represented by the `overflow` metric.  Storm also does 
some micro batching of tuples for performance/efficiency reasons so you may see 
the overflow with a very small number in it even if the queue is not full.
