Compared with open source Redis clusters, Tair (Redis OSS-compatible) cluster instances have the following advantages in terms of security, kernel performance, load balancing, and scaling:
Kernel performance improvement: The kernel performance of Tair cluster instances is optimized. The following items list some of the optimizations:
Accelerates disaster recovery and prevents broadcast storm problems that may be caused by the gossip protocol.
Allows data to be automatically and imperceptibly distributed across shards during the scaling of cluster instances.
Supports a large number of short-lived connections.
Convenient O&M and management: Compared with self-managed Redis databases, Tair cluster instances support multi-dimensional access control, elastic scaling, a variety of performance metrics, and a wide range of high-availability disaster recovery solutions. For more information, see Comparison between Tair (Redis OSS-compatible) and self-managed Redis.
Support for the proxy mode: Tair cluster instances support the proxy mode. By means of proxy nodes, the proxy mode allows you to change the instance architecture and use a cluster instance in the same manner as you use a standard instance. Proxy nodes can also balance loads, route commands, manage the traffic to read replicas, cache hotkey data, and support multiple databases in a cluster instance. For more information, see Features of proxy nodes.
