This topic lists the primary instance types for ApsaraDB RDS for MySQL YiTian instances and their detailed configurations.
YiTian instance types currently support only MySQL 8.0, 8.4, and 5.7.
YiTian instance types for the High-availability Edition and Cluster Edition are available in the China (Hangzhou), China (Shanghai), China (Beijing), China (Zhangjiakou), China (Ulanqab), China (Shenzhen), China (Guangzhou), China (Chengdu), Indonesia (Jakarta), China (Hong Kong), and Singapore regions. Support for more regions is gradually being rolled out. See the buy page for the latest information.
See the buy page for the list of regions that support YiTian instance types for the Basic Edition.
The available instance types may vary by region. See the buy page for the latest offerings.
The "maximum connections" value in the tables indicates the maximum number of processes that can connect simultaneously to an ApsaraDB RDS for MySQL instance.
A general-purpose instance type does not guarantee maximum IOPS or maximum I/O bandwidth. If your workload is sensitive to IOPS, select a dedicated instance type.
YiTian instances of the High-availability Edition and Cluster Edition support automatic storage expansion and automatic performance expansion. For more information, see Automatic storage and performance expansion.
