partitioning logic runs too often

[gordon chung]

gnocchi uses the reporting worker to partition tasks across each of the processing workers. by default reporter runs every 10s and processor worker every 5s. unfortunately, in any environment, small or large, the processor takes much longer than 10s to process it's data. because of that, the repartition messages that the reporter sends up queues up so the processor ends up running through a list of stale repartition messages before it can grab a new set of metrics.

we should either set reporter to report less frequently OR get it broadcast less frequently. i'm inclined to put a min period of 1min that the reporter can run at.

    Increase partitioning logic period

    gnocchi uses the reporting worker to partition tasks across each of
    the processing workers. by default reporter runs every 10s and
    processor worker every 5s. unfortunately, in any environment, small
    or large, the processor takes much longer than 10s to process it's
    data. because of that, the repartition messages that the reporter
    sends up queues up so the processor ends up running through a list
    of stale repartition messages before it can grab a new set of
    metrics.

    This calls for an increase in the period of which the reporter runs.
