ScyllaDB is a high-performance, distributed NoSQL database designed to handle large volumes of data with low latency. It is compatible with Apache Cassandra and offers features such as automatic sharding, high availability, and horizontal scalability. ScyllaDB is often used in environments where high throughput and low latency are critical, such as real-time analytics, IoT, and time-series data applications.
When working with ScyllaDB, you may encounter an AuthorizationFailure error. This typically manifests as an error message indicating that the user does not have the necessary permissions to perform a specific operation. This can occur during various database operations such as reading, writing, or modifying data.
Unauthorized: User does not have permission to execute the queryAccess Denied: Insufficient privilegesThe primary cause of an AuthorizationFailure error in ScyllaDB is insufficient permissions for the user attempting the operation. This can happen if the user's role does not include the necessary privileges or if the permissions have not been correctly assigned.
ScyllaDB uses role-based access control (RBAC) to manage permissions. Each user is assigned a role that defines their access rights. If a user lacks the required role or permissions, they will encounter authorization errors.
To resolve an AuthorizationFailure error, you need to ensure that the user has the appropriate permissions. Follow these steps to address the issue:
Check the roles assigned to the user. You can do this by executing the following CQL query:
SELECT role FROM system_auth.role_members WHERE member = 'username';
Replace 'username' with the actual username.
If the user lacks the required permissions, grant them using the GRANT statement. For example, to grant read access to a keyspace:
GRANT SELECT ON KEYSPACE keyspace_name TO username;
Replace keyspace_name and username with the appropriate values.
Ensure that the roles are correctly structured and that inherited roles provide the necessary permissions. Use the following query to check role hierarchies:
SELECT * FROM system_auth.role_members;

By following these steps, you can effectively resolve authorization failures in ScyllaDB and ensure that users have the necessary permissions to perform their operations.
