Amazon Ads Source dbt Package (Docs)

What does this dbt package do?

• Materializes Amazon Ads staging tables, which leverage data in the format described by this ERD. These staging tables clean, test, and prepare your Amazon Ads data from Fivetran's connector for analysis by doing the following:
  • Names columns for consistency across all packages and for easier analysis
  • Adds freshness tests to source data
  • Adds column-level testing where applicable. For example, all primary keys are tested for uniqueness and non-null values.
• Generates a comprehensive data dictionary of your Amazon Ads data through the dbt docs site.
• These tables are designed to work simultaneously with our Amazon Ads transformation package.

How do I use the dbt package?

Step 1: Prerequisites

To use this dbt package, you must have the following:

• At least one Fivetran Amazon_ads connector syncing data into your destination.
• A BigQuery, Snowflake, Redshift, PostgreSQL, or Databricks destination.

Step 2: Install the package (skip if also using the amazon_ads transformation package or ad_reporting combo package)

If you are not using the Amazon Ads transformation package or the Ad Reporting combination package, include the following amazon_ads_source package version in your packages.yml file.

TIP: Check dbt Hub for the latest installation instructions, or read dbt's Package Management documentation for more information on installing packages.

packages:
  - package: fivetran/amazon_ads_source
    version: [">=0.4.0", "<0.5.0"] # we recommend using ranges to capture non-breaking changes automatically

Step 3: Define database and schema variables

By default, this package runs using your destination and the amazon_ads schema. If this is not where your Amazon_ads data is (for example, if your Amazon_ads schema is named amazon_ads_fivetran), add the following configuration to your root dbt_project.yml file:

vars:
  amazon_ads_database: your_database_name
  amazon_ads_schema: your_schema_name 

Step 4: Disable models for non-existent sources

Your Amazon Ads connector may not sync every table that this package expects. If you do not have the PORTFOLIO_HISTORY table synced, add the following variable to your root dbt_project.yml file:

vars:
    amazon_ads__portfolio_history_enabled: False   # Disable if you do not have the portfolio table. Default is True.

(Optional) Step 5: Additional configurations

Union multiple connectors

If you have multiple amazon_ads connectors in Fivetran and would like to use this package on all of them simultaneously, we have provided functionality to do so. The package will union all of the data together and pass the unioned table into the transformations. You will be able to see which source it came from in the source_relation column of each model. To use this functionality, you will need to set either the amazon_ads_union_schemas OR amazon_ads_union_databases variables (cannot do both) in your root dbt_project.yml file:

vars:
    amazon_ads_union_schemas: ['amazon_ads_usa','amazon_ads_canada'] # use this if the data is in different schemas/datasets of the same database/project
    amazon_ads_union_databases: ['amazon_ads_usa','amazon_ads_canada'] # use this if the data is in different databases/projects but uses the same schema name

NOTE: The native source.yml connection set up in the package will not function when the union schema/database feature is utilized. Although the data will be correctly combined, you will not observe the sources linked to the package models in the Directed Acyclic Graph (DAG). This happens because the package includes only one defined source.yml.

To connect your multiple schema/database sources to the package models, follow the steps outlined in the Union Data Defined Sources Configuration section of the Fivetran Utils documentation for the union_data macro. This will ensure a proper configuration and correct visualization of connections in the DAG.

Passing Through Additional Metrics

By default, this package will select clicks, impressions, cost, purchases_30_d, and sales_30_d from the source reporting tables to store into the staging models. If you would like to pass through additional metrics to the staging models, add the following configurations to your dbt_project.yml file. These variables allow the pass-through fields to be aliased (alias) and transformed (transform_sql) if desired, but not required. Use the following format for declaring the respective pass-through variables:

Note Ensure you exercised due diligence when adding metrics to these models. The metrics added by default (clicks, impressions, cost, purchases, and sales amount) have been vetted by the Fivetran team maintaining this package for accuracy. There are metrics included within the source reports, for example, metric averages, which may be inaccurately represented at the grain for reports created in this package. You want to ensure whichever metrics you pass through are indeed appropriate to aggregate at the respective reporting levels provided in this package.

vars:
    amazon_ads__campaign_passthrough_metrics: 
      - name: "new_custom_field"
        alias: "custom_field"
    amazon_ads__ad_group_passthrough_metrics:
      - name: "unique_string_field"
        transform_sql: "coalesce(unique_string_field, 'NA')"
    amazon_ads__advertised_product_passthrough_metrics: 
      - name: "new_custom_field"
        alias: "custom_field"
        transform_sql: "coalesce(custom_field, 'NA')" # reference alias in transform_sql if aliasing 
      - name: "a_second_field"
    amazon_ads__targeting_keyword_passthrough_metrics:
      - name: "this_field"
    amazon_ads__search_term_ad_keyword_passthrough_metrics:
      - name: "unique_string_field"
        alias: "field_id"

Changing the Build Schema

By default, this package will build the Amazon_ads staging models (11 views, 11 tables) within a schema titled (<target_schema> + amazon_ads_source) in your destination. If this is not where you would like your Amazon Ads staging data to be written, add the following configuration to your root dbt_project.yml file:

models:
    amazon_ads_source:
      +schema: my_new_schema_name # leave blank for just the target_schema

Change the source table references

If an individual source table has a different name than the package expects, add the table name as it appears in your destination to the respective variable. (This is not available when running the package on multiple unioned connectors):

IMPORTANT: See this project's dbt_project.yml variable declarations to see the expected names.

vars:
    amazon_ads_<default_source_table_name>_identifier: your_table_name
