Aggregation

Message describing an aggregation. The message includes the aggregation type, parameters, and the field on which to perform the aggregation.

JSON representation 
{
  "field": string,

  // Union field aggregation_function can be only one of the following:
  "count": {
    object (Count)
  },
  "sum": {
    object (Sum)
  },
  "histogram": {
    object (Histogram)
  },
  "frequency": {
    object (Frequency)
  }
  // End of list of possible types for union field aggregation_function.
}
Fields
field

string

The name of the field on which to aggregate.

Union field aggregation_function.

aggregation_function can be only one of the following:
count

object (Count)

Count the number of matching objects.
sum

object (Sum)

Sum over a numeric field.
histogram

object (Histogram)

Creates a bucketed histogram of field values.
frequency

object (Frequency)

Creates a frequency distribution of all field values.

Count

This type has no fields.

Object count.

Sum

This type has no fields.

Sum of field values.

Histogram

Histogram of bucketed assets counts by field value.

JSON representation 
{
  "lowerBounds": [
    number
  ]
}
Fields
lowerBounds[]

number

Lower bounds of buckets. The response will contain n+1 buckets for n bounds. The first bucket will count all assets for which the field value is smaller than the first bound. Subsequent buckets will count assets for which the field value is greater or equal to a lower bound and smaller than the next one. The last bucket will count assets for which the field value is greater or equal to the final lower bound. You can define up to 20 lower bounds.

Frequency

This type has no fields.

Frequency distribution of all field values.

AggregationResult

Message describing a result of an aggregation.

JSON representation 
{
  "field": string,

  // Union field result can be only one of the following:
  "count": {
    object (Count)
  },
  "sum": {
    object (Sum)
  },
  "histogram": {
    object (Histogram)
  },
  "frequency": {
    object (Frequency)
  }
  // End of list of possible types for union field result.
}
Fields
field

string

Union field result.

result can be only one of the following:
count

object (Count)
sum

object (Sum)
histogram

object (Histogram)
frequency

object (Frequency)

Count

The result of a count aggregation.

JSON representation 
{
  "value": string
}
Fields
value

string (int64 format)

Sum

The result of a sum aggregation.

JSON representation 
{
  "value": number
}
Fields
value

number

Histogram

The result of a bucketed histogram aggregation.

JSON representation 
{
  "buckets": [
    {
      object (Bucket)
    }
  ]
}
Fields
buckets[]

object (Bucket)

Buckets in the histogram. There will be n+1 buckets matching n lower bounds in the request. The first bucket will be from -infinity to the first bound. Subsequent buckets will be between one bound and the next. The final bucket will be from the final bound to infinity.

Bucket

A histogram bucket with a lower and upper bound, and a count of items with a field value between those bounds. The lower bound is inclusive and the upper bound is exclusive. Lower bound may be -infinity and upper bound may be infinity.

JSON representation 
{
  "lowerBound": number,
  "upperBound": number,
  "count": string
}
Fields
lowerBound

number

Lower bound - inclusive.
upperBound

number

Upper bound - exclusive.
count

string (int64 format)

Count of items in the bucket.

Frequency

The result of a frequency distribution aggregation.

JSON representation 
{
  "values": {
    string: string,
    ...
  }
}
Fields
values

map (key: string, value: string (int64 format))

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.
