Getting Started with DataStax Astra for Cassandra

1. Setup ASTRA

Create an Astra Instance
Create the Table

Once the database is ready go to CQLConsole and create the table

CREATE TABLE IF NOT EXISTS starter_orders (
  order_id uuid,
  product_id uuid,
  product_quantity int,
  product_name text,
  product_price decimal,
  added_to_order_at timestamp,
  PRIMARY KEY ((order_id), product_id)
 ) WITH CLUSTERING ORDER BY (product_id DESC);

Create an token with role Databse administrator

2. Build ASTRA SDK

git clone https://github.com/clun/astra-sdk-java.git
cd astra-sdk-java
mvn clean install -Dmaven.test.skip=true

Then add the SDK client to the pom.xmlL

<dependency>
    <groupId>com.datastax.astra</groupId>
    <artifactId>astra-spring-boot-starter</artifactId>
    <version>2021.1-SNAPSHOT</version>
</dependency>

3. Setup your application

Copy the db id, the cloud region and the apptoken in Application.properties

astra.cloudRegion=us-east-1
astra.databaseId=de9d6c10-c8e6-43f0-95dc-72517cf801ec
astra.applicationToken=AstraCS:lAkKZnycDWcAxCyOiBMdaoie:025dbbb5904xxx
astra.keyspace=bootiful

4. Run TESTS

Open this application in an IDE
Open pom.xml and check reference to the spring boot starter

<dependency>
  <groupId>com.datastax.astra</groupId>
  <artifactId>astra-spring-boot-starter</artifactId>
  <version>2021.1-SNAPSHOT</version>
</dependency>

Start working with AstraClientTest

should_list_available_db()
should_create_new_serverless_db()
should_create_cqlSession()

Back to the Astra UI create a new KEYSPACE namespace1
Update code to provide namespace name

should_use_documentAPI()

Run the Application

mvn spring-boot:run

5. Check in the DB
