DataStax

This is the implementation of the DataStax data handler for MindsDB.

DataStax Astra DB is a cloud database-as-a-service based on Apache Cassandra. DataStax also offers DataStax Enterprise (DSE), an on-premises database built on Apache Cassandra, and Astra Streaming, a messaging and event streaming cloud service based on Apache Pulsar.

​

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:

• user is the user to authenticate.
• password is the password to authenticate the user.
• secure_connection_bundle is the path to the secure_connection_bundle zip file.

​

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": "user",
        "password": "pass",
        "secure_connection_bundle": "/home/Downloads/file.zip"
    };

You can use this established connection to query your table as follows:

SELECT *
FROM astra_connection.keystore.example_table
LIMIT 10;
