Amazon RDS and Option Groups

Amazon RDS provides an empty default option group for each new DB instance.

You cannot modify this default option group, but any new option group that you create derives its settings from the default option group.

To apply an option to a DB instance, you must do the following:

1. Create a new option group, or copy or modify an existing option group.
2. Add one or more options to the option group.
3. Associate the option group with the DB instance.

snapshots Both DB instances and DB snapshots can be associated with an option group.

more memory Options require additional memory to run on a DB instance
