"# Azure Machine Learning Pipeline with KustoStep\n",
|
|
"To use Kusto as a compute target from [Azure Machine Learning Pipeline](https://aka.ms/pl-concept), a KustoStep is used. A KustoStep enables the functionality of running Kusto queries on a target Kusto cluster in Azure ML Pipelines. Each KustoStep can target one Kusto cluster and perform multiple queries on them. This notebook demonstrates the use of KustoStep in Azure Machine Learning (AML) Pipeline.\n",

"## Before you begin:\n",
|
|
"\n",
|
|
"1. **Have an Azure Machine Learning workspace**: You will need details of this workspace later on to define KustoStep.\n",
|
|
"2. **Have a Service Principal**: You will need a service principal and use its credentials to access your cluster. See [this](https://docs.microsoft.com/en-us/azure/active-directory/develop/howto-create-service-principal-portal) for more information.\n",
|
|
"3. **Have a Blob storage**: You will need a Azure Blob storage for uploading the output of your Kusto query."
