Azure Synapse Access Control client library for Java - version 1.0.0-beta.4

Artikel
07/26/2022

Azure Synapse is a limitless analytics service that brings together enterprise data warehousing and Big Data analytics. It gives you the freedom to query data on your terms, using either serverless on-demand or provisioned resources—at scale. Azure Synapse brings these two worlds together with a unified experience to ingest, prepare, manage, and serve data for immediate BI and machine learning needs.

The Azure Synapse Analytics access control client library enables programmatically managing role assignments.

Getting started

Adding the package to your project

Maven dependency for the Azure Synapse Access Control client library. Add it to your project's POM file.

<dependency>
    <groupId>com.azure</groupId>
    <artifactId>azure-analytics-synapse-accesscontrol</artifactId>
    <version>1.0.0-beta.4</version>
</dependency>

Prerequisites

Java Development Kit (JDK) with version 8 or above
An [Azure subscription][azure_sub].

An existing Azure Synapse workspace. If you need to create an Azure Synapse workspace, you can use the Azure Portal or Azure CLI.

az synapse workspace create \
    --name <your-workspace-name> \
    --resource-group <your-resource-group-name> \
    --storage-account <your-storage-account-name> \
    --file-system <your-storage-file-system-name> \
    --sql-admin-login-user <your-sql-admin-user-name> \
    --sql-admin-login-password <your-sql-admin-user-password> \
    --location <your-workspace-location>

Authenticate the client

In order to interact with the Azure Synapse service, you'll need to create an instance of the RoleDefinitionsClient or RoleAssignmentsClient class. You would need a workspace endpoint and client secret credentials (client id, client secret, tenant id) to instantiate a client object using the default DefaultAzureCredential examples shown in this document.

The DefaultAzureCredential way of authentication by providing client secret credentials is being used in this getting started section but you can find more ways to authenticate with azure-identity.

Create/Get credentials

To create/get client secret credentials you can use the Azure Portal, Azure CLI or Azure Cloud Shell

Here is an Azure Cloud Shell snippet below to

Create a service principal and configure its access to Azure resources:

az ad sp create-for-rbac -n <your-application-name> --skip-assignment

Output:

{
    "appId": "generated-app-ID",
    "displayName": "dummy-app-name",
    "name": "http://dummy-app-name",
    "password": "random-password",
    "tenant": "tenant-ID"
}

Troubleshooting

Default HTTP client

All client libraries by default use the Netty HTTP client. Adding the above dependency will automatically configure the client library to use the Netty HTTP client. Configuring or changing the HTTP client is detailed in the HTTP clients wiki.

Default SSL library

All client libraries, by default, use the Tomcat-native Boring SSL library to enable native-level performance for SSL operations. The Boring SSL library is an Uber JAR containing native libraries for Linux / macOS / Windows, and provides better performance compared to the default SSL implementation within the JDK. For more information, including how to reduce the dependency size, refer to the performance tuning section of the wiki.

Next steps

Several Synapse Java SDK samples are available to you in the SDK's GitHub repository. These samples provide example code for additional scenarios commonly encountered while working with Azure Synapse Analytics.
