RDS Parameter Group

A Relational Database Service (RDS) Parameter Group in AWS is a collection of parameters that are applied to an RDS instance or cluster. These parameters control the configuration and behavior of the instance or cluster, such as memory and storage settings, I/O operations, transaction isolation levels, query processing options, and other database-related configurations. By using parameter groups with different sets of parameters for each instance or cluster in your environment, you can customize the performance and behavior of your databases to meet specific requirements.
