# Nested Fields

[Nested fields](https://cloud.google.com/bigquery/docs/nested-repeated) represent complex data structures within a single column. This allows you to store arrays and structs in a column, enabling more sophisticated data modeling and reducing the need for complex joins.

This is why we have decided to include them in our ingestion to have as much visibility as possible when integrating with BigQuery.

## Columns

We treat the inner fields as first class columns. These columns have their own popularity and other attributes independent of each other, as they are all treated as separate columns.

## Lineage

When ingesting nested fields, you will be able to see lineage going to/from them.
