Cluster

Instances of the same type have different memory specifications. You can select instances of different specifications based on application scenarios.

This section describes cluster instance specifications. The instance specifications depend on the selected CPU model.

The default maximum number of connections has been adjusted. Query the number of connections based on the instance creation time. For details about the number of connections for instances created before July 2021, see Historical Node Specifications.
