How do I create a Cassandra DataBase?

Create a Cassandra Database: Complete the following steps to create and launch a Cassandra database using the DataStax Astra console.

Each Cassandra database launches with one Capacity Unit (CU) by default, which represents three database nodes that are grouped together. You can later resize the database to increase the number of CUs if increased capacity is required.

All Cassandra databases are created with a replication factor of three to provide optimal uptime and data integrity. Additionally, each Cassandra database provides the following specifications:

• A single datacenter
• 500 GB of storage per node
• A single keyspace
• Capacity for up to 200 tables

1. In the DataStax Astra console, click Create New Database.
2. Select the region where you want to launch your database from the dropdown menu.
   Note: Premium regions are denoted by an icon with double dollar signs ().
3. Define the database details:
   1. Enter a name for the database.
      Important: The database name cannot be altered after the database is created. Take care when entering a database name and use a meaningful naming convention.
   2. Enter the keyspace name where tables for the database will be created.
   3. Enter the name of the database user, which can be reentered as the database user for additional databases. DataStax Astra on Google Cloud Platform forces all names to lowercase; enclose the name in quotes to preserve case or use special characters in the name.
      CAUTION: Do not enter cassandra as the user name for the database. This user name is reserved as the superuser by default.
   4. Enter a password for the database user.
4. Choose the compute size for the database.
   Note: Compute size cannot be changed after database creation. However, you can add CUs to increase the storage size of the database for the selected service tier.
   • Developer: low-cost development option, 25 GB storage.
   • Startup: starter configuration for development and light production workloads.
   • Standard: higher throughput, lower latency, 99.9% uptime SLA, plus support.
   • Enterprise: highest throughput, lowest latency, 99.99% uptime SLA, and best support tier.
5. To view estimated costs for the database, select Per Minute or Per Month. The estimates are calculated both for when the database is running and parked.
   Note: Each Cassandra database launches with one Capacity Unit (CU) by default.
6. Click Launch Database to create the database.

An email is sent when database creation is complete, including a link to the database. Click View Database to view your database. When the database is active, you can access credentials for connecting your database.

You can then Connect to your database using DataStax Studio, Docker, cqlsh, or through one of the DataStax Drivers.
