Changing a DB Instance Class

Scenarios

This section describes how to change the CPU or memory of your instance to suit your service requirements.

Precautions

  • Instances can be scaled up or down.
  • Services will be interrupted for 5 to 10 minutes when you change DB instance CPU or memory, so you are advised to perform these operations during off-peak hours.
  • You are not advised to perform DDL operations when changing the CPU and memory.

    A data definition language (DDL) is a syntax for defining data structures and database objects. Common examples of DDL statements include CREATE, ALTER, and DROP. DDL is used to create, modify, and delete database objects, such as tables, indexes, views, functions, stored procedures, and triggers.
