Redis Sentinel provides high availability (HA) services for open source Redis. Tair is compatible with Redis Sentinel to support services that run Sentinel. This topic describes how to enable the Sentinel-compatible mode in the Tair console.
Overview of Redis Sentinel
Redis Sentinel provides open source Redis with features such as master and replica monitoring, fault alerting, and automatic failover. Redis Sentinel is suitable for many business scenarios that use self-managed Redis databases and require high reliability. To facilitate the migration of these self-managed Redis databases to the cloud, Alibaba Cloud provides the Sentinel-compatible mode.
Tair uses the HA component developed by Alibaba Cloud without the need to use Redis Sentinel. For more information about the HA component, see Functions and features.
After you enable the Sentinel-compatible mode, you can run the Sentinel commands described in the following table.
