Developing a Java app using Azure Managed Instance for Apache Cassandra (v4.x Driver).

Azure Managed Instance for Apache Cassandra provides automated deployment and scaling operations for managed open-source Apache Cassandra datacenters. It accelerates hybrid scenarios and reduces ongoing maintenance.

This quick start demonstrates how to connect to a Cassandra Managed instance cluster. You'll then build a user profile console app, output as shown in the following image, with sample data.

Prerequisites

• Before you can run this sample, you must have the following prerequisites:
  • An Azure Managed Instance for Apache Cassandra cluster. Check out our Quickstart guide here.
  • Networking access from this application to your Azure Managed Instance for Apache Cassandra cluster (the service only deploys private IP addresses injected into a Virtual network).
  • Java Development Kit (JDK) 1.8+
    • On Ubuntu, run apt-get install default-jdk to install the JDK.
  • Be sure to set the JAVA_HOME environment variable to point to the folder where the JDK is installed.
  • Download and install a Maven binary archive
    • On Ubuntu, you can run apt-get install maven to install Maven.
  • Git
    • On Ubuntu, you can run sudo apt-get install git to install Git.

Running this sample

1. Clone this repository using git clone https://github.com/Azure-Samples/azure-cassandra-mi-java-v4-getting-started.

2. Update parameters in src/main/resources/application.conf:

   1. Enter the datacenter name in the DC field.
   2. Enter username and password in datastax-java-driver.advanced.auth-provider section, and the IP addresses of your cluster seed nodes in datastax-java-driver.basic.contact-points.

3. Run mvn clean package from the top level folder to build the project. This will generate cassandrami-examples.jar under target folder.

4. Run java -cp target/cassandrami-examples.jar com.azure.cassandrami.examples.UserProfile in a terminal to start your java application.

About the code

The code included in this sample is intended to get you quickly started with a Java command line application that connects to Azure Managed Instance for Apache Cassandra.
