In data warehouses, you can use materialized views to precompute and store aggregated data such as the sum of sales. Materialized views in these environments are often referred to as summaries, because theystore summarized data. They can also be used to precompute joins with or without aggregatio...
Materializationsare strategies for persisting dbt models in a warehouse. There are five types of materializations built into dbt. They are: table view incremental ephemeral materialized view You can also configurecustom materializationsin dbt. Custom materializations are a powerful way to extend dbt's...
