For details about the service model corresponding to the service model number, see Service model.
Operations per Second (OPS): number of operations executed per second by a database

In different service models, test the OPS of DB instances 4.0 with different shard classes based on the preset low-level data volume in 2. For details, see the content in bold in Table 1.

The table lists only the performance data in typical scenarios.
