schema
This is a work in progress document. While this configuration applies to multiple resource types, the documentation has only been written for seeds.
Definition
Optionally specify a custom schema for a model or seed. (To specify a schema for a snapshot, use the target_schema
config).
When dbt creates a relation (table/view) in a database, it creates it as: {{ database }}.{{ schema }}.{{ identifier }}
, e.g. analytics.finance.payments
The standard behavior of dbt is:
- If a custom schema is not specified, the schema of the relation is the target schema (
{{ target.schema }}
). - If a custom schema is specified, by default, the schema of the relation is
{{ target.schema }}_{{ schema }}
.

Usage
Models
Configure groups of models from the dbt_project.yml
file.
models:
jaffle_shop: # the name of a project
marketing:
+schema: marketing
Configure individual models using a config block:
{{ config(
schema='marketing'
) }}
Seeds
seeds:
+schema: mappings
Tests
Customize the name of the schema in which tests configured to store failures will save their results:
tests:
+store_failures: true
+schema: the_island_of_misfit_tests
