sqlmesh-cube 0.1.1.dev3

SQLMesh extension for generating Cube semantic layer configurations

SQLMesh is a next-generation data transformation framework designed to ship data quickly, efficiently, and without error. Data teams can efficiently run and deploy data transformations written in SQL or Python with visibility and control at any size.

It is more than just a dbt alternative.

Core Features

Get instant SQL impact analysis of your changes, whether in the CLI or in SQLMesh Plan Mode

Virtual Data Environments

• See a full diagram of how Virtual Data Environments work
• Watch this video to learn more

• Create isolated development environments without data warehouse costs
• Plan / Apply workflow like Terraform to understand potential impact of changes
• Easy to use CI/CD bot for true blue-green deployments

Efficiency and Testing

Running this command will generate a unit test file in the tests/ folder: test_stg_payments.yaml

Runs a live query to generate the expected output of the model

sqlmesh create_test tcloud_demo.stg_payments --query tcloud_demo.seed_raw_payments "select * from tcloud_demo.seed_raw_payments limit 5"

# run the unit test
sqlmesh test

MODEL (
  name tcloud_demo.stg_payments,
  cron '@daily',
  grain payment_id,
  audits (UNIQUE_VALUES(columns = (
      payment_id
  )), NOT_NULL(columns = (
      payment_id
  )))
);

SELECT
    id AS payment_id,
    order_id,
    payment_method,
    amount / 100 AS amount, /* `amount` is currently stored in cents, so we convert it to dollars */
    'new_column' AS new_column, /* non-breaking change example  */
FROM tcloud_demo.seed_raw_payments

test_stg_payments:
model: tcloud_demo.stg_payments
inputs:
    tcloud_demo.seed_raw_payments:
      - id: 66
        order_id: 58

      - id: 3
        order_id: 3
        payment_method: coupon
        amount: 100
outputs:

        new_column: new_column
      - payment_id: 109
        order_id: 95
        payment_method: coupon
        amount: 24.0
        new_column: new_column
      - payment_id: 3
        order_id: 3
        payment_method: coupon
        amount: 1.0
        new_column: new_column

• Never build a table more than once
• Track what data’s been modified and run only the necessary transformations for incremental models
• Run unit tests for free and configure automated audits

Level Up Your SQL

Write SQL in any dialect and SQLMesh will transpile it to your target SQL dialect on the fly before sending it to the warehouse.

• Debug transformation errors before you run them in your warehouse in 10+ different SQL dialects
• Definitions using simply SQL (no need for redundant and confusing Jinja + YAML)
• See impact of changes before you run them in your warehouse with column-level lineage

For more information, check out the website and documentation.
