public final class DimensionKey

Describes a Data Feed Metric dimension name-value pairs.

A metric advisor data feed schema DataFeedSchema defines dimension names and metric for a data source, For example, a SQL data source for a wholesale company can have "product_category" and "city" as dimension names and "revenue" as a metric.

A combination of value for all dimension names identifies a metric time-series. A DimensionKey can hold such a combination, for example, [ product_category=men-shoes, city=redmond ] identifies one specific time-series.

A DimensionKey can also have partial dimensions, for example, [ city=redmond ] identifying a group of time-series having value for "city" dimension as "redmond".

Two DimensionKey with same dimension name-value pairs identifies the same time-series or time-series group, this means equals(Object o) return true.
