The secret ARN is needed in the subsequent step.

Optionally, copy programmatic code for accessing your secret using your preferred programming languages (which is not needed for this post).Īfter you create the secret, you can retrieve the secret ARN by choosing the secret on the Secrets Manager console.For Select which RDS database this secret will access, choose your database.For Select the encryption key, choose DefaultEncryptionkey.For Select secret type, select Credentials for RDS database.On the Secrets Manager console, choose Secrets.

To store a new secret, complete the following steps: Storing credentials in Secrets Manager takes only a few minutes. Because Amazon Redshift retrieves and uses these credentials, they are transient, not stored in any generated code, and discarded after the query runs. AWS Secrets Manager provides a centralized service to manage secrets and can be used to store your MySQL database credentials. Configuring AWS Secrets Manager for remote database credentialsĪmazon Redshift needs database credentials to issue a federated query to a MySQL database. For more information about VPC networking, see Working with a DB instance in a VPC. If your Amazon Redshift cluster and Aurora MySQL instances are in the different VPC, you can set up VPC peering or other networking to allow Amazon Redshift to make connections to your Aurora MySQL instances. This way, you can add the security group for the Amazon Redshift cluster to the inbound rules of the security group for the Aurora MySQL DB instance. To make sure both Aurora MySQL DB instances can accept connections from the Amazon Redshift cluster, you should make sure that both your Amazon Redshift cluster and Aurora MySQL instances are in the same Amazon Virtual Private Cloud (Amazon VPC) and subnet group. To try this new feature, create a new Amazon Redshift cluster in a sql_preview maintenance track and Aurora MySQL instance and load sample TPC data into both data stores.

In this post, we share information about how to get started with this new federated query feature to MySQL. Your data can then be more available to other analytics and machine learning (ML) tools, rather than siloed in disparate data stores. With this lake house architecture expansion to support more operational data stores, you can query and combine data more easily in real time and store data in open file formats in your Amazon Simple Storage Service (Amazon S3) data lake. Today, we’re launching a new feature of Amazon Redshift federated query to Amazon Aurora MySQL and Amazon RDS for MySQL to help you expand your operational databases in the MySQL family. We’re always listening to your feedback and, in April 2020, we announced general availability for federated querying to Amazon Aurora PostgreSQL and Amazon Relational Database Service (Amazon RDS) for PostgreSQL to enable you to query data across your operational databases, your data warehouse, and your data lake to gain faster and deeper insights not possible otherwise. Since we launched Amazon Redshift as a cloud data warehouse service more than seven years ago, tens of thousands of customers have built analytics workloads using it.
