Metric aggregations
Metric aggregations let you perform simple calculations such as finding the minimum, maximum, and average values of a field.
Types of metric aggregations
There are two types of metric aggregations: single-value metric aggregations and multi-value metric aggregations.
Single-value metric aggregations
Single-value metric aggregations return a single metric, for example, sum
, min
, max
, avg
, cardinality
, or value_count
.
Multi-value metric aggregations
Multi-value metric aggregations return more than one metric. These include stats
, extended_stats
, matrix_stats
, percentile
, percentile_ranks
, geo_bound
, top_hits
, and scripted_metric
.
