Redshift scoped permissions vs normal user permissions

Sure, I can explain the difference between scoped permissions and normal user permissions in the context of Amazon Redshift.

1. Normal User Permissions:

   • With normal user permissions in Amazon Redshift, you grant access to specific database objects (such as tables, views, schemas) or actions (such as SELECT, INSERT, UPDATE) to individual users or groups of users.
   • These permissions are granted directly to the user or group, and they apply across the entire database cluster.
   • For example, you might grant a user permission to read data from a specific table in a database.

2. Scoped Permissions:

   • Scoped permissions in Amazon Redshift are a feature that allows you to grant permissions within the context of a specific workload management (WLM) queue or a session.
   • With scoped permissions, you can control access to resources or actions based on the context in which they are being accessed.
   • Scoped permissions are typically used in conjunction with WLM queues to control access to resources based on workload priorities or resource utilization.
   • For example, you can grant a user permission to execute queries in a specific WLM queue, but restrict their access to certain tables or views based on the queue they are using.

In summary, the main difference between scoped permissions and normal user permissions in Amazon Redshift is the context in which the permissions apply. Normal user permissions apply across the entire database cluster and control access to specific objects or actions, while scoped permissions apply within the context of a specific workload management queue or session, allowing more granular control over resource access based on workload priorities or session characteristics.
