> The metrics of the queues for each component are very helpful to reason about the performance issues of a topology.
> For instance, for the applications with strong time constraint (e.g., threat detection), if the elements in the input queue of a bolt have a long sojourn time, it indicates that the user should increase the parallelism of that bolt to reduce the processing delay.
> However, the metrics on the DisruptorQueue currently available are limited. More useful metrics, such as average sojourn time and average throughput are expected.
