> The key was generated by following forum:
> (timestamp - timestamp % range) + random.nextInt(range)
> where the default value of range is 60k(1 minute).  
> With the default "range" value, the key will have the same prefix in one minute. And
the process rate is around 40k/s ( namely 2400k/m ). And the key range is 60k, so roughly
40 operation for each key by average ( namely 1 insertion and another 39 update ).
> Following is the benchmark result: The highest is around 40K/s and lowest is around 28k/s,
average is around 35.5k/s
> See attached "ManagedStateBenchmark.png" for screen shot
