For a master/standby DCS Redis 4.0 or later basic instance, there are two domain names displayed on the instance details page of the console: a read/write address (master node) and a read-only address (standby node).
Proxy Cluster Redis DCS for Redis provides Proxy Cluster instances, which use Linux Virtual Server (LVS) and proxies to achieve high availability. Proxy Cluster instances have the following features: The client is decoupled from the cloud service.

Self-Hosted Redis Cluster Migration with redis-shake (Online) redis-shake is an open-source tool for migrating data online or offline (by importing backup files) between Redis Clusters.
Two replicas mean that the instance has two nodes (one master and one standby). AZ AZs where the master node and standby node of the instance are located. Configure instance network settings. Select the created VPC and Subnet.
Importing the Backup File Import the RDB file (or files) to the cloud server. The cloud server must be connected to the target DCS instance.
This parameter specifies the maximum number of connections on a single node (single shard).
This parameter specifies the maximum number of connections on a single node (single shard).
This parameter specifies the maximum number of connections on a single node (single shard).
Using ELB for Public Access to DCS Overview Currently, Huawei Cloud DCS Redis 4.0 and later cannot be bound with elastic IP addresses (EIPs) and cannot be accessed over public networks directly.
Use persistent connections ("pconnect" in Redis terminology) to ensure performance.

The addresses remain unchanged before and after master/standby switchover. You can use either address to connect to the instance. Master/Standby (basic edition): Each instance has one IP address and two domain name addresses.

QPS per shard for a Redis 6.0 enterprise (performance) instance node: 400,000/s; QPS per shard for an enterprise (storage) instance node: 70,000/s. Monitoring Provides only basic statistics. Provides more than 30 monitoring metrics and customizable alarm threshold and policies.
Master/Standby, read/write splitting, and Redis Cluster instances Scaling out/in (replica quantity change) Before adding or removing replicas for a Redis Cluster instance, ensure that automated cluster topology refresh is enabled.
Is the Read-only Address of a Master/Standby Instance Connected to the Master or Standby Node?
