Q1Domain Verified
In the context of "The Complete Elasticsearch Metrics & Analytics Course 2026," which of the following aggregation types is *most* suitable for performing a running total calculation across a series of documents, especially when dealing with time-series data where the order of aggregation matters?
`avg` aggregation
`percentiles` aggregation
`sum` aggregation
`scripted_metric` aggregation
Q2Domain Verified
According to "The Complete Elasticsearch Metrics & Analytics Course 2026," when analyzing large datasets with nested structures for metrics, which aggregation strategy offers the best balance between performance and the ability to drill down into specific sub-fields without incurring excessive overhead?
Converting nested fields to a single string field and using `terms` aggregation.
Utilizing the `nested` aggregation with appropriate path definitions.
Flattening the nested documents into separate parent documents before aggregation.
Employing a `terms` aggregation on the root document fields and then manually processing nested data.
Q3Domain Verified
In "The Complete Elasticsearch Metrics & Analytics Course 2026," consider a scenario where you need to identify the top N most frequent occurrences of a particular field and simultaneously calculate the average value of another field for each of those top N occurrences. Which aggregation combination is the most idiomatic and efficient way to achieve this?
Two independent `terms` aggregations, one for frequency and another for average, then merging the results client-side.
A `terms` aggregation with a `top_hits` sub-aggregation to retrieve document details.
A `terms` aggregation followed by a separate `avg` aggregation on the entire dataset.
A `terms` aggregation with an `avg` sub-aggregation nested within it.
