ScyllaDB

Summary​

This document covers the information to gather from ScyllaDB in order to configure a Qarbine data service. The data service will use the Qarbine DynamoDB API driver. You can define multiple data services that access the same ScyllaDB endpoint though with varying credentials. Once a data service is defined, you can manage which Qarbine principals have access to it and its associated Singlestore data. A Qarbine administrator has visibility to all data services.

Overview​

ScyllaDB has an interface for the Cassandra API and also one for the DynamoDB API. Qarbine currently supports the DynamoDB interface to ScyllaDB. It provides a fast, easy, and powerful API that enables analytics on DynamoDB data applications without any query changes, application migration, or data transformations. For detailed compatibility information and functional differences, it’s recommended to consult the ScyllaDB documentation at https://www.scylladb.com/alternator and
https://opensource.docs.scylladb.com/stable/alternator/compatibility.html.

ScyllaDB Configuration​

Qarbine requires the ScyllaDB endpoint and optionally a database to configure a data service using the DynamoDB API driver.

Open the ScyllaDB cloud portal at https://cloud.scylladb.com/.

Navigate to the General tab

  

Verify the following

  

Currently, Qarbine offers a DynamoDB API interface to ScyllaDB.

Navigate to the Connect tab

  

Click on the following row

  

Copy the endpoint as highlighted below.

  

This value will serve as the server template value in the Qarbine data service definition.

Your ScyllaDB cluster may have username and password authentication turned on. If so then when configuring the Qarbine data service, set the accessKeyId to the desired ScyllaDB username and the secretAccessKey to its corresponding password. Environment variables may be used to obtain these values.

To prevent accidental modifications to your data it is essential to have roles to limit permissions. For more details see
https://opensource.docs.scylladb.com/stable/operating-scylla/security/authorization#create-role

For more information about role-based access control and user management see

The above information can now be used in the steps described in the DynamoDB API Access document.
