Aggregations
An aggregation summarizes data as metrics or statistics. They can answer questions like
- What is the total number of products in my catalog?
- What is the average rating of each product per customer segment?
ParadeDB supports two types of aggregations: bucket and metric aggregations. Bucket aggregations group the data into buckets based on certain fields. For instance, a histogram is a type of bucket aggregation. Metric aggregations compute statistics over a field. For instance, an average is a type of metric aggregation.
