在一个 AWS Redshift 实例下创建（实际上）多个数据库

Question

We are using AWS RDS Postgres at the moment and are thinking of shifting to AWS Redshift.

Problem

We want to create two databases (1 for STAGING, 1 for PRODUCTION) under it but we came to know that we can only create ONE database under an instance.

Research

I found this answer which said that I can create multiple schemas and then simply set the default schema for roles that way I can virtually achieve different databases for PROD and QA and I will not have to change any of my queries. But while reading the developer guide , at page 382 I read that DATABASE ROLES is listed under Unsupported PostgreSQL Features .

Question

How can I achieve this functionality given my use case in AWS Redshift?

Answer 1

With Redshift you can create multiple databases within one cluster. (max of around 60)

the command

create database newdbname;

will do this.

Any one query can ONLY access one database at a time so correct permissions can be set up per database.

So, I think you have everything you need.
