dbt-maxcompute 1.8.0a8

The MaxCompute adapter plugin for dbt

dbt-maxcompute

Welcome to the dbt-maxCompute repository! This project aims to extend the capabilities of dbt (data build tool) for users of Alibaba MaxCompute, a cutting-edge data processing platform.

What is dbt?

dbt empowers data analysts and engineers to transform their data using software engineering best practices. It serves as the T in the ELT (Extract, Load, Transform) process, allowing users to organize, cleanse, denormalize, filter, rename, and pre-aggregate raw data, making it analysis-ready.

About MaxCompute

MaxCompute is Alibaba Group's cloud data warehouse and big data processing platform, supporting massive data storage and computation, widely used for data analysis and business intelligence. With MaxCompute, users can efficiently manage and analyze large volumes of data and gain real-time business insights.

This repository contains the foundational code for the dbt-maxcompute adapter plugin. For guidance on developing the adapter, please refer to the official documentation.

Important Note

The README you are currently viewing will be updated with specific instructions and details on how to utilize the adapter as development progresses.

Adapter Versioning

This adapter plugin follows semantic versioning. The initial version is v1.8.0-a0, designed for compatibility with dbt Core v1.8.0. Since the plugin is in its early stages, the version number a0 indicates that it is an Alpha release. A stable version will be released in the future, focusing on MaxCompute-specific functionality and aiming for backwards compatibility.

Getting Started

Install the plugin

# we use python 3.9 for this example
conda create --name dbt-maxcompute-example python=3.9
conda activate dbt-maxcompute-example

pip install dbt-core
pip install dbt-maxcompute

Configure dbt profile:

1. Create a file in the ~/.dbt/ directory named profiles.yml.
2. Copy the following and paste into the new profiles.yml file. Make sure you update the values where noted.

jaffle_shop: # this needs to match the profile in your dbt_project.yml file
  target: dev
  outputs:
    dev:
      type: maxcompute
      project: dbt-example # Replace this with your project name
      schema: default # Replace this with schema name, e.g. dbt_bilbo
      endpoint: http://service.cn-shanghai.maxcompute.aliyun.com/api # Replace this with your maxcompute endpoint
      accessId: XXX # Replace this with your accessId(ak)
      accessKey: XXX # Replace this with your accessKey(sk)

Currently we support the following parameters：

Field	Description	Default Value
type	Specifies the type of database connection; must be set to "maxcompute" for MaxCompute connections.	"maxcompute"
project	The name of your MaxCompute project.	N/A (Must be specified)
endpoint	The endpoint URL for connecting to MaxCompute.	N/A (Must be specified)
accessId	The Access ID for authentication with MaxCompute.	N/A (Must be specified)
accessKey	The Access Key for authentication with MaxCompute.	N/A (Must be specified)
schema	The namespace schema that the models will use in MaxCompute.	N/A (Must be specified)

Notes: The fields marked as "N/A (Must be specified)" indicate that these values are required and do not have default values.

Run you dbt models

If you are new to DBT, we have prepared a Tutorial document for your reference. Of course, you can also access the official documentation provided by DBT (but some additional adaptations may be required for MaxCompute)

Developers Guide

If you want to contribute or develop the adapter, use the following command to set up your environment:

pip install -r dev-requirements.txt
