Types of Aggregations
Elasticsearch provides a variety of aggregation types, each serving a different purpose. Here are some common types of aggregations:
- Metric Aggregations: Calculate metrics such as average, sum, min, max, etc., on numeric fields.
- Bucket Aggregations: Group documents into “buckets” based on certain criteria.
- Pipeline Aggregations: Perform aggregations on the results of other aggregations.
- Matrix Aggregations: Analyze multi-dimensional data in a matrix format.
