DataVault4dbt - A Comprehensive Guide

Below is an example model to illustrate this structure:

{%- set yaml_metadata -%} hashkey: ‘hk_account_h’ business_keys: - account_key - account_number source_models: stage_account {%- endset -%}

{%- set metadata_dict = fromyaml(yaml_metadata) -%}

{{ datavault4dbt.hub(hashkey=metadata_dict.get(‘hashkey’), business_keys=metadata_dict.get(‘business_keys’), source_models=metadata_dict.get(‘source_models’) ) }}

This example consists of the following parts:

1. DBT Configuration: • {{ config(materialized=’incremental’) }} : Sets the materialization type to incremental, meaning that the table will be updated incrementally rather than being rebuilt from scratch each time 2. Metadata Definition: • The yaml_metadata block contains the definition of the hash key, business keys, and source models in YAML syntax. This metadata must be written correctly to ensure accurate parsing and SQL generation
