ApsaraDB for Redis - Supports Proxy Query Cache to Address Problems Caused by Hotkeys
Target customers: customers that use performance-enhanced cluster instances of ApsaraDB for Redis Enhanced Edition (Tair). Features released: ApsaraDB for Redis provides the proxy query cache feature to help customers address skewed requests caused by hotkeys that receive a large number of write requests. After you enable this feature, proxy nodes cache the request and response data of hotkeys. If a proxy node receives a duplicate request within the validity period, the proxy node directly returns a response to the client. This way, clients can receive responses without the need to interact with backend data shards. To use this feature, make sure that you use performance-enhanced cluster instances of ApsaraDB for Redis Enhanced Edition (Tair), and proxy nodes in your instances are upgraded to the latest minor version.
