Class Group

java.lang.Object

io.fluxzero.common.api.search.Group

public class Group
extends Object

Represents a group key for aggregating documents in DocumentStats.

A Group consists of one or more path-value pairs used to categorize documents during aggregation. Each group corresponds to a unique combination of values across the specified groupBy paths.

Groups are typically created during the in-memory computation of statistics in a GetDocumentStatsResult, and identify which subset of documents a given DocumentStats applies to.

Example:
If grouping on "status" and "region", one Group might contain:
{"status": "active", "region": "EU"}
