CompressedMetricsSink

A constant-memory-complexity data structure to store time series data points

It produces a ganglia-like feature, that if the new data to be added is newer than the maximum this can contain, a compact will be performed to increase the resolution (time range each bucket contains) according to getNextResolution, so this data structure can record newer data without losing the earliest data points.

When first created, the size of the array will be the number of buckets to keep in memory The time range represented by each bucket is configured by resolution

Since: 8/11/16.
