In this blog post, we will discuss AWS RDS option groups.

Option Groups:

Apart from parameter groups to define RDS instance type specific parameters, AWS RDS also support option groups. Options groups consist of optional features that can be added to your AWS RDS instance that are not already covered in parameter groups. Each AWS RDS instance type has its own set of options (parameter) that you can define using an option group.

By default, AWS RDS creates a default option group when you created your RDS instance. Like default parameter group, you cannot modify a default option group. To configure an option group, you need to create your own option group. Not all RDS instance type supports option group, for instance PostgreSQL does not support an option group.

Option groups options are of two types, persistent and permanent. Persistent options can’t be removed from an option group while DB instances are associated with the option group. On the other hand, permanent options cannot be removed event if no instance is associated.

Next, we are going to create an option group for MySQL RDS instance.
