Connect to MySQL and MariaDB from Amazon Aurora and Amazon RDS for PostgreSQL using the mysql_fdw extension

When dealing with multiple database engines or schemas that share data with each other, you’re faced with the difficulty of establishing cross-engine database connectivity. To overcome this challenge, PostgreSQL offers foreign data wrappers (FDW), which are libraries that facilitate communication with external data sources by abstracting the complexities of data source connection and data retrieval. […]

Schedule scaling for Amazon Aurora replicas using AWS Application Auto Scaling

In this post, we demonstrate how to modify the Amazon Aurora reader auto scaling configuration on a schedule using AWS Application Auto Scaling, on top of the existing auto scaling policies. When your application grows, the load on your database will most likely grow as your application saves larger amounts of data. Whether it’s the […]

Automatically scale Amazon RDS storage using Amazon CloudWatch and AWS Lambda

Customer databases are constantly growing. When you increase storage for a database in Amazon Relational Database Service (Amazon RDS), you can’t make further storage modifications for either 6 hours or until storage optimization has completed on the instance, whichever is longer. Amazon RDS storage autoscaling increases storage by 10 GiB, 10% of currently allocated storage, […]
