Class MovFnPipelineAggregator
java.lang.Object
org.elasticsearch.search.aggregations.pipeline.PipelineAggregator
org.elasticsearch.search.aggregations.pipeline.MovFnPipelineAggregator
This pipeline aggregation gives the user the ability to script functions that "move" across a window
of data, instead of single data points. It is the scripted version of MovingAvg pipeline agg.
Through custom script contexts, we expose a number of convenience methods:
- max
- min
- sum
- unweightedAvg
- linearWeightedAvg
- ewma
- holt
- holtWintersMovAvg
The user can also define any arbitrary logic via their own scripting, or combine with the above methods.
