Aggregations

Cross-entity aggregations allow you to create features at different granularities than their source data.

This is particularly useful in two scenarios:

1. When you need to transform data granularity as sources are not available

   • For example, aggregating a fact table by foreign keys to create array of rows

2. When high-granularity data is not necessary

   • For instance, aggregating metrics for page views or orders at a country level instead of individual records

Note: This functionality is available only for offline features.
