本章節主(zhu)要介紹Redis4.0的(de)命(ming)令。
DCS Redis4.0基(ji)于開(kai)(kai)源(yuan)4.0.14版本進行開(kai)(kai)發(fa)，兼容開(kai)(kai)源(yuan)的協(xie)議(yi)和命(ming)令。
本章節(jie)主(zhu)要(yao)介(jie)紹DCS Redis4.0命(ming)令的兼(jian)容性，包括支持命(ming)令列表，禁用命(ming)令列表。命(ming)令的具(ju)體詳(xiang)細語(yu)法，請前(qian)往查看。
DCS Redis緩存實例支持Redis的絕大部分命令，具體支持的命令，請參考Redis4.0命令，任何兼容Redis協議的(de)客戶端(duan)都可以訪問DCS。
- 因安全原因，部分Redis命令在分布式緩存服務中被禁用，具體請見Redis4.0禁用的命令。
- DCS集群實例支持多個key，但不支持跨slot訪問的Redis命令列表，如實例受限使用命令所示。
- 部分Redis命令使用時有限制，具體請見部分命令使用限制。
Redis4.0支持的命令
下表列舉了(le)Redis4.0單機、主備、cluster集群實(shi)例支持的Redis命令。
下表列舉了Redis 4.0 Proxy集群實例支持的Redis命令。
下表(biao)列舉了Redis 4.0讀寫分離實例支持(chi)的Redis命令。
說明
Redis高版本(ben)的命(ming)令，在低(di)版本(ben)中(zhong)不被兼容(rong)。判斷DCS Redis是否支(zhi)持某個命(ming)令，可通過(guo)在Redis-cli執行該(gai)命(ming)令，如果(guo)得到（error）ERR unknown command ‘xxx’的提示，則說明不支(zhi)持該(gai)命(ming)令。
Redis 4.0 Cluster版本集群(qun)實例使用pipeline時，要確保(bao)管(guan)道中的(de)命令(ling)都能在同一分片執行。
