Migrates data pipelines between various frameworks

Databricks Workflows Migrator (wkmigrate)

Project Description

wkmigrate is a Python library for migrating data pipelines to Databricks workflows from various frameworks. Users can programmatically create or migrate workflows with a simple set of commands.

Pipeline definitions are read from a user-specified source system, translated for compatibility with Databricks workflows, and either directly created or stored in json or yml files.

Installation

Use pip install wkmigrate to install the PyPi package.

Compatibility

wkmigrate is a standalone project. Using some features (e.g. serverless jobs compute options) may require a premium-tier Databricks workspace.

Using the Workflow Migrator

To use the wkmigrate, install the library using the %pip install wkmigrate method or install the Python wheel directly in your environment.

Once the library has been installed, create source and target definition stores for the migration.

from wkmigrate.definition_store_builder import build_definition_store

# Create the source definition store (an ADF instance):
factory_options = {
    "tenant_id": "<TENANT_ID>",
    "client_id": "<CLIENT_ID>",
    "client_secret": "<CLIENT_SECRET>",
    "subscription_id": "<SUBSCRIPTION_ID>",
    "resource_group_name": "<RESOURCE_GROUP_NAME>",
    "factory_name": "<FACTORY_NAME>"
}
factory_store = build_definition_store(
    "factory_definition_store", 
    factory_options
)

# Create the target definition store (a Databricks workspace):
workspace_options = {
    "authentication_type": "pat",
    "host_name": "<DATABRICKS_HOST_URL>",
    "pat": "<DATABRICKS_PERSONAL_ACCESS_TOKEN>",
}
workspace_store = build_definition_store(
    "workspace_definition_store", 
    workspace_options
)                        

Use the load method to get definitions from a source.

pipeline = factory_store.load(pipeline_name="<PIPELINE_NAME>")                      

Use pipeline_translator.translate() to translate definitions for compatibility with Databricks workflows.

from wkmigrate import pipeline_translator
translated_pipeline = pipeline_translator.translate(pipeline)

Use the dump method to sync workflows into a target.

workspace_store.dump(translated_pipeline)
