Elasticsearch's aggregation analysis allows users to perform complex data aggregations and analyses on large volumes of data stored in Elasticsearch indices. It provides various types of aggregations, such as term aggregation, range aggregation, date histogram aggregation, etc., enabling users to extract statistical information and insights from the data.
For example, term aggregation can be used to count the number of occurrences of each value in a specific field. Suppose you have an index containing user logs, and you want to know how many times each user has logged in. You can use term aggregation on the "user_id" field to get this information.
In addition, range aggregation can be used to calculate statistical data within a specific range. For instance, if you want to know the number of requests per minute during a certain time period, you can use range aggregation on the timestamp field.
