Yes, TencentDB for SQL Server has an upper limit on IOPS (Input/Output Operations Per Second), which depends on the specific instance type and configuration you choose.
For example, if you select a standard instance with default settings, the IOPS may be capped at a certain level (e.g., 20,000 IOPS). However, you can increase the IOPS by upgrading to a higher-performance instance or enabling additional storage options like SSDs.
Tencent Cloud offers TencentDB for SQL Server with flexible performance tiers. If your workload requires higher IOPS, you can choose a high-performance instance or scale up storage to meet demanding requirements. Additionally, Tencent Cloud provides automatic performance optimization features to help maintain stable I/O operations.
For specific IOPS limits, refer to the official Tencent Cloud documentation or consult with their support team to select the best configuration for your needs.
