Aggregations
Cross-entity aggregations allow you to create features at different granularities than their source data.
This is particularly useful in two scenarios:
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
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.
