Query Tag feature in DBT is a database-specific configuration. In this article, let see how to customize it for Snowflake.

Query tags are a Snowflake parameter that can be quite useful later on when searching in the QUERY_HISTORY view.

Default Query Tag can be set in the Profiles.yml

This will be applied to all the queries triggered from DBT to Snowflake.

3 ways to configure query tag

1. Configure it in dbt_project.yml, the drawback in this approach is we can only add string, can’t execute a macro with the current dbt version. For now, DBT supports only a few lists of contexts in the project YAML file.

2. Configure it under each model config, the drawback is repeating the same config in all models, which is not a good practice.

Solution

3. Override the default query tag macro and customize it based on the requirement.

Before each model, the Snowflake session-level query tags will be updated. Once the model run is completed, it will be automatically reset to default query tag which is set in profiles.yml

alter session set query_tag = ‘dbt_model_name’

The above same code is also maintained under this ever-growing git repository.
