Compute Unit

Last updated: 2025-11-27 17:00:28

This document describes the computing power specification of TDSQL-C for MySQL Serverless.
Note: 
The current list of compute unit configurations may include some specifications that have been discontinued. Refer to the actual purchase page for the available specifications.
The compute unit configurations supported vary by region. Refer to the table below for the support status in each region.
For the purchase of compute unit configurations of 32 CCU and above, submit a ticket to contact our staff for assistance.
Starting from October 12, 2024, TDSQL-C for MySQL will optimize and adjust the maximum storage capacity, maximum IOPS, and I/O bandwidth corresponding to each instance specification through technical upgrades. For Serverless-related adjustments, see Serverless Limitation Changes.
