This is the implementation of the DataStax data handler for MindsDB. https://docs.datastax.com/en/astra-db-serverless/index.html[DataStax Astra DB] is a cloud database-as-a-service based on Apache Cassandra. DataStax also offers on-premises solutions, DataStax Enterprise (DSE) and Hyper-Converged Database (HCD), as well as Astra Streaming, a messaging and event streaming cloud service based on Apache Pulsar.

​
Prerequisites

Before proceeding, ensure the following prerequisites are met:
  1. Install MindsDB locally via Docker or Docker Desktop.
  2. To connect DataStax to MindsDB, install the required dependencies following this instruction.
  3. Create an Astra DB database.

​
Implementation

DataStax Astra DB is API-compatible with Apache Cassandra and ScyllaDB. Therefore, its implementation extends the ScyllaDB handler and is using the scylla-driver Python library. The required arguments to establish a connection are as follows:

​
Usage

In order to make use of this handler and connect to the Astra DB database in MindsDB, the following syntax can be used: 
CREATE DATABASE astra_connection
WITH
    engine = "astra",
    parameters = {
        "user": "token",
        "password": "application_token",
        "secure_connect_bundle": "/home/Downloads/file.zip"
    };
or, reference the bundle from Datastax s3 as: 
CREATE DATABASE astra_connection
WITH ENGINE = "astra",
PARAMETERS = {
    "user": "token",
    "password": "application_token",
    "secure_connect_bundle": "https://datastax-cluster-config-prod.s3.us-east-2.amazonaws.com/32312-b9eb-4e09-a641-213eaesa12-1/secure-connect-demo.zip?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=AK..."
}
You can use this established connection to query your table as follows: 
SELECT *
FROM astra_connection.keystore.example_table
LIMIT 10;
