This article describes the compute specifications of the TDSQL-C for MySQL Serverless service.
Note:
Currently, there may be some sold-out compute specifications in the configuration list. Please refer to the actual purchase page for the latest information.
Different regions support different compute specifications. Please check the regional support in the table below.
To purchase compute configurations of 32 CCU or higher, please 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.
Due to data center maintenance, the purchase channels for Guangzhou Zone 3 and Guangzhou Zone 4 have been temporarily closed since November 21, 2025. We apologize for any inconvenience caused.
