Aggregation

Aggregation #

An aggregation summarizes your data as metrics, statistics, or other analytics.

Pizza organizes aggregations into the following categories:

  • Metric aggregations that calculate metrics, such as a sum or average, from field values.
  • Bucket aggregations that group documents into buckets, also called bins, based on field values, ranges, or other criteria.

Metric aggregations #

  • avg aggregation
    A single-value metrics aggregation that computes the average of numeric values that are extracted from the aggregated documents.
  • max aggregation
    A single-value metrics aggregation that keeps track and returns the maximum value among the numeric values extracted from the aggregated documents.
  • min aggregation
    A single-value metrics aggregation that keeps track and returns the minimum value among numeric values extracted from the aggregated documents.
  • percentiles aggregation
    A multi-value metrics aggregation that calculates one or more percentiles over numeric values extracted from the aggregated documents.
  • sum aggregation
    A single-value metrics aggregation that sums up numeric values that are extracted from the aggregated documents.
  • value_count aggregation
    A single-value metrics aggregation that counts the number of values that are extracted from the aggregated documents.

Bucket aggregations #

  • date_histogram aggregation
    A histogram aggregation that can only be used with date or date range values.
  • terms aggregation
    A multi-bucket value source based aggregation where buckets are dynamically built - one per unique value.
