Yes, there is a relationship between the size of the TDSQL-C MySQL version instance and the maximum IOPS. Generally, larger instances offer higher maximum IOPS due to their increased storage capacity and processing power.
For example, a smaller TDSQL-C instance might be limited to 1000 IOPS, while a larger instance could support up to 5000 IOPS or more. This variation is because larger instances often come with more disk space and better hardware specifications, allowing them to handle more input/output operations per second.
When choosing an instance size, consider your application's I/O requirements to ensure optimal performance. If your application needs high IOPS, selecting a larger instance size would be beneficial.
In the context of cloud services, platforms like Tencent Cloud offer various instance sizes for TDSQL-C MySQL, allowing you to choose based on your specific performance needs.
