|
// the data and allow the user to specify a custom script that is executed for
|
|
// each window of data.
|
|
//
|
|
// You must pass a script to process the values. There are a number of predefined
|
|
// script functions you can use as described here:
|
|
// https://www.elastic.co/guide/en/elasticsearch/reference/7.0/search-aggregations-pipeline-movfn-aggregation.html#_pre_built_functions.

|
|
// Example:
|
|
// agg := elastic.NewMovFnAggregation(
|
|
// "the_sum", // bucket path
|
|
// elastic.NewScript("MovingFunctions.stdDev(values, MovingFunctions.unweightedAvg(values))"),
|
|
// 10, // window size
|
|
// )
