public class EventTimestampIndexer
extends Object

Assigns indexes to event timestamps in order satisfy Cortex's time ordering constraint for samples.
For each time series samples must be written ordered by time. This class assigns index numbers to event timestamps that can be used as label values to differentiate different time series. Index numbers are guaranteed to be increasing for each event timestamp and event timestamps are guaranteed to be increasing for each index number.
