New feature The proxy query cache feature is released. After this feature is enabled for an ApsaraDB for Redis instance, the proxy servers of the instance can cache the requests and responses for hot keys. If the same requests are received from a client, the proxy servers retrieve the responses to the requests from the cache and send the responses to the client. This feature helps prevent skewed requests that are caused by hot keys. 2021-05-14 All regions Use proxy query cache to address issues caused by hotkeys
API operation More parameters are supported by the CreateInstance operation of ApsaraDB for Redis.
  • Port: specifies the port that is used by an instance.
  • Tag.N.Key and Tag.N.Value: specify the key and value of a tag that is added to an instance.
  • DryRun: specifies whether to perform a precheck.
