    public final class Aggregation
extends com.google.protobuf.GeneratedMessageV3
implements AggregationOrBuilder
     Describes how to combine multiple time series to provide a different view of
 the data.  Aggregation of time series is done in two steps. First, each time
 series in the set is _aligned_ to the same time interval boundaries, then the
 set of time series is optionally _reduced_ in number.

 Alignment consists of applying the `per_series_aligner` operation
 to each time series after its data has been divided into regular
 `alignment_period` time intervals. This process takes _all_ of the data
 points in an alignment period, applies a mathematical transformation such as
 averaging, minimum, maximum, delta, etc., and converts them into a single
 data point per period.

 Reduction is when the aligned and transformed time series can optionally be
 combined, reducing the number of time series through similar mathematical
 transformations. Reduction involves applying a `cross_series_reducer` to
 all the time series, optionally sorting the time series into subsets with
 `group_by_fields`, and applying the reducer to each subset.

 The raw time series data can contain a huge amount of information from
 multiple sources. Alignment and reduction transforms this mass of data into
 a more manageable and representative collection of data, for example "the
 95% latency across the average of all tasks in a cluster". This
 representative data can be more easily graphed and comprehended, and the
 individual time series data is still available for later drilldown. For more
 details, see [Filtering and

      • getPerSeriesAlignerValue

        public int getPerSeriesAlignerValue()
         An `Aligner` describes how to bring the data points in a single
 time series into temporal alignment. Except for `ALIGN_NONE`, all
 alignments cause all the data points in an `alignment_period` to be
 mathematically grouped together, resulting in a single data point for
 each `alignment_period` with end timestamp at the end of the period.

 Not all alignment operations may be applied to all time series. The valid
 choices depend on the `metric_kind` and `value_type` of the original time
 series. Alignment can change the `metric_kind` or the `value_type` of
 the time series.

 Time series data must be aligned in order to perform cross-time
 series reduction. If `cross_series_reducer` is specified, then
 `per_series_aligner` must be specified and not equal to `ALIGN_NONE`
 and `alignment_period` must be specified; otherwise, an error is
 returned.

      • getGroupByFieldsList

        public com.google.protobuf.ProtocolStringList getGroupByFieldsList()
         The set of fields to preserve when `cross_series_reducer` is
 specified. The `group_by_fields` determine how the time series are
 partitioned into subsets prior to applying the aggregation
 operation. Each subset contains time series that have the same
 value for each of the grouping fields. Each individual time
 series is a member of exactly one subset. The
 `cross_series_reducer` is applied to each subset of time series.
 It is not possible to reduce across different resource types, so
 this field implicitly contains `resource.type`.  Fields not
 specified in `group_by_fields` are aggregated away.  If
 `group_by_fields` is not specified and all the time series have
