This file implements the logic for applying reduce-to operators to time series data. Reduce-to operators aggregate multiple data points in a time series into a single value, allowing for concise representation of data in table or value panels.

Detailed Documentation​

applyReduceTo​

Purpose:​

Applies a reduce-to operator (e.g., last, sum, avg, min, max) to each time series in a query result, reducing the series to a single data point representing the aggregated value.

Parameters:​

  • result ([]*v3.Result): The slice of query results to process.
  • queryRangeParams (*v3.QueryRangeParamsV3): The query range parameters, including the composite query and builder queries containing the reduce-to operator definition.

Returns:​

None. The function modifies the result slice in place, reducing the series to single values as necessary.
