Guide to Using Metadata Security in Amazon Redshift for Multi-Tenant Applications

/ Tutorial

Introduction

Amazon Redshift, a fully-managed data warehousing service, has introduced a new feature – metadata security. This feature allows administrators to control the visibility of catalog data in a multi-tenant environment based on user roles and permissions. With metadata security, users can only access the metadata for databases, schemas, tables, and views that they have been granted access to. This guide will provide a detailed walkthrough of how to leverage metadata security in Amazon Redshift for developing and deploying multi-tenant applications.
