- Average Aggregation: Calculates the average value of a numeric field.
- Sum Aggregation: Calculates the sum of values in a numeric field.
- Min Aggregation: Finds the minimum value in a numeric field.
- Max Aggregation: Finds the maximum value in a numeric field.
- Stats Aggregation: Provides statistics such as count, sum, min, max, and average.
Elasticsearch Aggregations
Elasticsearch is not just a search engine; it’s a powerful analytics tool that allows you to gain valuable insights from your data. One of the key features that make Elasticsearch so powerful is its ability to perform aggregations.
In this article, we’ll explore Elasticsearch aggregations in detail, explaining what they are, how they work, and providing examples with outputs to help you understand them better.
