Instance Types

Last updated: 2022-05-09 14:53:41

This document describes the instance types of TDSQL-C for MySQL, including general and dedicated.

Instance Type Description
General
  • A general instance exclusively uses the allocated memory and disk resources and shares the CPU resources with other general instances on the same physical machine.
  • A general instance benefits from higher specifications at a lower cost by sharing CPU resources.
  • A general instance's disk capacity is unaffected by its CPU and memory specs.
  • Dedicated
  • A dedicated instance has exclusive access to the CPU, memory, and disk resources (if CPU pinning is enabled). It has long-term stability and is unaffected by the activities of other instances on the physical machine.
  • A dedicated instance with the highest configurations can monopolize a physical machine and all of its resources.
