Materialized segments are only available for BigQuery.
When to Use Materialized Segments
Use materialized segments when you need to target a specific list of users defined by complex queries in your data warehouse. Common use cases include:- Beta testers: Target users who have opted into beta programs
- High-value customers: Target users based on purchase history or engagement metrics
- Cohort analysis: Target users who signed up during a specific period
- Custom segments: Any segment that’s easier to define in SQL than with attribute criteria
How Materialized Segments Work
- You define a SQL query that returns a list of entity IDs
- Confidence runs this query against your BigQuery instance
- Confidence loads the resulting IDs into a segment
- You can use this segment for targeting in rules, experiments, and rollouts
