Redis Cluster Version
Last Updated：2021-03-16
Redis instance with cluster architecture contains multiple multiparts and multiple proxy nodes. It is compatible with Redis 3.2 protocols and commands, adopts a distributed architecture, and supports horizontal and vertical capacity scaling (will be put into use). The cluster instance can scale the data capacity and improve network/CPU/QPS capabilities quickly by horizontally scaling the number of multiparts, and can carry much higher traffic capacity than the standard instances.
Redis cluster version of instance can freely choose the cache node specifications and number of multiparts and flexibly create the required instance specifications.

Cluster Specifications
| Item | Description |
|---|---|
| User’s total available memory | User’s available memory of cache node * Number of multiparts |
| Total maximum connections | Maximum connections of cache nodes * number of multiparts |
| Total maximum private network bandwidth | Maximum private network bandwidth of cache node * Number of multiparts |
| Total CPU processing power | CPU processing power of cache node * Number of multiparts |

Number of Optional Replicas
| Number of replicas | Data replica | Single multipart content | Description |
|---|---|---|---|
| 1 | Single replica of data | Contains 1 cache node: 1 master node | Do not provide the data reliability and do not support the backup and persistence |
| 2 | Double replica of data | Contain 2 cache nodes: 1 master node + 1 standby node | Provide the data reliability and support the backup and persistence |
