Aggregations compile Signals into a set of summaries that you can use to enrich the search experience through recommendations and boosting.

Fusion uses SQL to produce these signal summaries. SQL is a familiar query language that is well suited to data aggregation. Fusion’s SQL Aggregation Engine is powerful and flexible.

Aggregations are created automatically whenever you enable signals or recommendations. This topic explains how to create or modify aggregations individually. You can do this using the Fusion UI or the Jobs API. For more information, see Creating Aggregations.
