# Dedup Processor Plugin
If a metric sends the same value over successive intervals, suppress sending
the same value to the TSD until this many seconds have elapsed. This helps
graphs over narrow time ranges still see timeseries with suppressed datapoints.
This feature can be used to reduce traffic when metric's value does not change over
time while maintain proper precision when value gets changed rapidly
Filter metrics whose field values are exact repetitions of the previous values.
