This document describes the latest specifications of TencentDB for SQL Server primary instances.
Note:
The memory defined in the specifications of single-node (formerly Basic Edition) instances of cloud disk edition and two-node (formerly High Availability/Cluster Edition) instances of cloud disk edition includes the memory used by the TencentDB management services, database services, and underlying operating system. Therefore, the displayed available memory of an instance is smaller than the actual memory defined in the instance specification.
