Mastering Data Pipeline Efficiency: A Comprehensive Guide to Implementing Snapshot and Incremental Loads with dbt

Understand the Data Model:

Example: Suppose you have a data model with tables for orders, customers, and products. 

Understand the relationships between these tables, such as orders belonging to customers 

and products associated with orders.

Set Up dbt Project:

Reference: Follow the dbt Quickstart guide to set up your dbt project: dbt Quickstart.

Configure dbt Profiles:

Example: Configure your profiles.yml file with connection details for your data warehouse:

my_profile:
  target: dev
  outputs:
    dev:
      type: snowflake
      account: my_account
      user: my_user
      password: my_password
      warehouse: my_warehouse
      database: my_database

Create dbt Models:

Example: Create a dbt model to transform the orders data:

-- models/orders.sql
{{ config(materialized='table') }}
 

select order_id, 
customer_id,
order_date,
total_amount from   
{{ ref('stg_orders') }}

Implement Snapshot Loads:
Example: Use dbt's {{ config(snapshot_strategy='timestamp') }} to create snapshots:

-- models/orders_snapshot.sql
{{ config(snapshot_strategy='timestamp') }}

select
    order_id,
    customer_id,
    order_date,
    total_amount
from
    {{ ref('stg_orders') }}

Implement Incremental Loads:

Example: Use dbt's {{ config(incremental_strategy='timestamp') }} to create incremental models:

-- models/orders_incremental.sql
{{ config(incremental_strategy='timestamp') }}
select
    order_id,
    customer_id,
    order_date,
    total_amount
from
    {{ ref('stg_orders') }}

Testing:
