The sample creates a simple keyspace and table with a multi-threaded app, and throws data in based on threads and no. of records.

• Before you can run this sample, you must have the following :
  • An Apache Cassandra cluster and networking access to it. Check out portal quickstart for Azure Managed Instance for Apache Cassandra.
  • 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.

1. Update cassandra-related parameters, and number of threads/records to load, in java-exmple/src/main/resources/application.conf.
2. Run mvn clean package from java-examples folder to build the project. This will generate cassandra-mi-load-tester-1.0.0-SNAPSHOT.jar under target folder.
3. Run java -jar target/cassandra-mi-load-tester-1.0.0-SNAPSHOT.jar in a terminal to start your java application. This will create a keyspace and user table, and then run a load test with many concurrent threads.
