class DedupValueFunction(step: Long, size: Int, next: ValueFunction) extends ValueFunction
If it is expensive to overwrite, then the immediate pass through behavior of other functions can be undesirable. This implementation uses a buffer to track the last n values over time for a given normalization function. This is typically to allow for use-cases where data may be reported on many nodes and thus some data is received out of order with many values for a given time.
Value parameters
- next
-
Normalized values will be passed to the this function.
- size
-
Size of the buffer.
- step
-
Step size between successive values.
