Review request for mesos, Benjamin Hindman and Vinod Kone. Repository: mesos-git Description ------- The first part of this change is the removal of the archive operation. This also exposes a TimeSeries data structure used by Statistics. The goal here is to provide reasonable historical information for high frequency time series that rapidly exceed capacity. TimeSeries allows a window of values to be stored, while "sparsifying" older values when the capacity is exceeded. See the documentation on TimeSeries for details. An alternative, more deterministic approach, is to use sampling on older values. Both approaches have their advantages and disadvantages.
