Azure Data Factory Orchestrator

Type	Pre-Set
Image	$DATAOPS_ADF_RUNNER_IMAGE

The Azure Data Factory (ADF) Orchestrator is a pre-set orchestrator that executes pre-existing pipelines registered in Azure Data Factory in the customer's Azure subscription account.

note

This orchestrator inherits from the Azure Orchestrator. Therefore, should you require further pre- or post-processing, call the Azure Orchestrator.

It is possible to mix the Azure and ADF orchestrator functionalities in the same job.

Usage

To use this orchestrator, the following must be created and present:

An Azure Resource Group
A working Data Factory instance
All of the required datasets
Any linked services used by the pipeline, like Azure Blob Storage and Office 365
The ADF pipeline and any child pipelines

In other words, you must ensure that the ADF pipeline and all of its dependencies are fully defined before using this orchestrator.

The following YAML script describes how to define an ADF job:

pipelines/includes/local_includes/adf_jobs/my_adf_job.yml
"My ADF Job":
  extends:
    - .agent_tag
  stage: "Batch Ingestion"
  image: $DATAOPS_ADF_RUNNER_IMAGE
  variables:
    DATAOPS_ADF_ACTION: START
    DATAOPS_ADF_FACTORY_NAME: XXXX
    DATAOPS_ADF_PIPELINE_NAME: XXXX
    DATAOPS_ADF_RESOURCE_GROUP: XXXX
    DATAOPS_ADF_TIMEOUT: 300
    DATAOPS_ADF_PIPELINE_RERUN_FROM: Failure

    # use one of the following connection methods
    # identity inheritance
    DATAOPS_USE_IDENTITY: 1

    # or default vault expansion
    SET_AZ_KEYS_TO_ENV: 1

    # or custom vault expansion
    AZURE_USER: DATAOPS_VAULT(PATH.TO.USERNAME.IN.VAULT)
    AZURE_PASSWORD: DATAOPS_VAULT(PATH.TO.PASSWORD.IN.VAULT)
  script:
    - /dataops
  icon: https://dataops-public-assets.s3.eu-west-2.amazonaws.com/adf.png

Connecting to Azure

To connect to Azure, the Azure Data Factory orchestrator supports two methods. Use one or the other but not both.

1. Username and password

To use the Azure orchestrator, you must provide your Azure username and password to the DataOps pipeline to connect to the Azure services, which will, in turn, connect to Azure Data Factory. Setting the environment variables AZURE_USER and AZURE_PASSWORD achieves this.

We recommend that you keep your third-party credentials in the DataOps Vault. Storing them at the default paths AZURE.DEFAULT.USER and AZURE.DEFAULT.PASSWORD allows you to retrieve them by setting the environment variable SET_AZ_KEYS_TO_ENV.

Use the DATAOPS_VAULT() functionality to retrieve your credentials if you have stored your credentials at different vault paths.

variables:
  AZURE_USER: DATAOPS_VAULT(PATH.TO.USERNAME.IN.VAULT)
  AZURE_PASSWORD: DATAOPS_VAULT(PATH.TO.PASSWORD.IN.VAULT)

2. Inheriting permissions from the virtual machine

The Azure Data Factory orchestrator also supports using the Virtual Machine's identity to connect to Azure. To utilize this, set the variable DATAOPS_USE_IDENTITY.

Supported parameters

Parameter	Required/Default	Description
`DATAOPS_ADF_ACTION`	REQUIRED	Must be `START` to use the orchestrator
`DATAOPS_ADF_FACTORY_NAME`	REQUIRED	The factory name
`DATAOPS_ADF_PIPELINE_NAME`	REQUIRED	The pipeline name
`DATAOPS_ADF_RESOURCE_GROUP`	REQUIRED	Resource Group name
`DATAOPS_ADF_PIPELINE_PARAMETERS`	Optional	File path for the ADF pipeline parameters (JSON)
`DATAOPS_ADF_PIPELINE_RERUN_FROM`	Optional. Defaults to `START`	Defines the ADF Pipeline recovery behavior in case the DataOps ADF job retries. Possible values are `FAILURE`, `START` and `<Name of activity>`
`DATAOPS_ADF_TIMEOUT`	Optional. Defaults to `300`	Time in seconds to wait for the completion of the ADF pipeline.
`DATAOPS_USE_IDENTITY`	Optional	If set, uses inherited Azure permission from VM
`SET_AZ_KEYS_TO_ENV`	Optional	If set, exports Azure username(`AZURE.DEFAULT.USER`) and password(`AZURE.DEFAULT.PASSWORD`) from vault to the variable

The following points expand on these supported parameters:

`DATAOPS_ADF_PIPELINE_RERUN_FROM`

The Azure Data Factory orchestrator supports the ability to rerun the ADF pipeline in the event of a failure or timeout by rerunning the existing DataOps pipeline instead of running a new DataOps pipeline.

caution

You cannot rerun a DataOps pipeline if another instance of the same DataOps pipeline has been run in the same environment.

The Azure Data Factory orchestrator uses the ADF pipeline runId to retry the run. Users can define the point where to resume the run in the variable DATAOPS_ADF_PIPELINE_RERUN_FROM.

The following DATAOPS_ADF_PIPELINE_RERUN_FROM values are available:

START

If this parameter is set to START, the ADF pipeline rerun will restart from the beginning.

FAILURE

If this value is set to FAILURE, the pipeline run will restart from the point where the ADF pipeline failed.

From Activity

The ADF pipeline run will restart from the specified activity name if defined.

Activity Name

START and FAILURE are case-sensitive reserved words for the Azure Data Factory orchestrator and cannot be used as an activity name.

Example jobs

Here are several examples of ADF orchestrator jobs:

Standard job setup for the ADF orchestrator

In the case of a failed ADF pipeline, use the default setup if you do not have to rerun the pipeline.

pipelines/includes/local_includes/adf_jobs/azure_data_factory_job.yml
"Azure Data Factory":
  extends:
    - .agent_tag
  stage: "Batch Ingestion"
  image: $DATAOPS_ADF_RUNNER_IMAGE
  variables:
    DATAOPS_ADF_ACTION: START
    DATAOPS_ADF_FACTORY_NAME: dataopslivedatafactory
    DATAOPS_ADF_PIPELINE_NAME: DummyPipeline
    DATAOPS_ADF_RESOURCE_GROUP: dataops
    DATAOPS_ADF_PIPELINE_PARAMETERS: $CI_PROJECT_DIR/dataops/azure/properties.json
    DATAOPS_USE_IDENTITY: 1
  script:
    - /dataops
  icon: https://dataops-public-assets.s3.eu-west-2.amazonaws.com/adf.png

Retrying the job from the failed ADF activity

Use the DATAOPS_ADF_PIPELINE_RERUN_FROM parameter if you do want to leverage the ADF pipeline recovery feature, as follows:

pipelines/includes/local_includes/adf/azure_data_factory_job.yml
"Azure Data Factory":
  extends:
    - .agent_tag
  stage: "Batch Ingestion"
  image: $DATAOPS_ADF_RUNNER_IMAGE
  variables:
    DATAOPS_ADF_ACTION: START
    DATAOPS_ADF_FACTORY_NAME: dataopslivedatafactory
    DATAOPS_ADF_PIPELINE_NAME: DummyPipeline
    DATAOPS_ADF_RESOURCE_GROUP: dataops
    DATAOPS_ADF_PIPELINE_PARAMETERS: $CI_PROJECT_DIR/dataops/azure/properties.json
    DATAOPS_ADF_PIPELINE_RERUN_FROM: FAILURE
    DATAOPS_USE_IDENTITY: 1
  script:
    - /dataops
  icon: https://dataops-public-assets.s3.eu-west-2.amazonaws.com/adf.png

Retrying the job from a specified ADF activity

Finally, here is an example of using a named ADF activity. Additionally, this example shows how to use the username/password authorization instead of the recommended inherited Azure identity.

pipelines/includes/local_includes/adf/azure_data_factory_job.yml
"Azure Data Factory":
  extends:
    - .agent_tag
  stage: "Batch Ingestion"
  image: $DATAOPS_ADF_RUNNER_IMAGE
  variables:
    DATAOPS_ADF_ACTION: START
    DATAOPS_ADF_FACTORY_NAME: dataopslivedatafactory
    DATAOPS_ADF_PIPELINE_NAME: DummyPipeline
    DATAOPS_ADF_RESOURCE_GROUP: dataops
    DATAOPS_ADF_PIPELINE_PARAMETERS: $CI_PROJECT_DIR/dataops/azure/properties.json
    DATAOPS_ADF_PIPELINE_RERUN_FROM: DummyActivity
    AZURE_USER: DATAOPS_VAULT(PATH.TO.USERNAME.IN.VAULT)
    AZURE_PASSWORD: DATAOPS_VAULT(PATH.TO.PASSWORD.IN.VAULT)
  script:
    - /dataops
