本文主要介绍缓存凯发k8官方网娱乐官方的服务支持的命令。
使用说明
鉴于标准版和集群版的架构差异，缓存服务对原生 redis 命令的支持程度有如下说明：
●由于集群版使用多分片存储数据，某些支持多 key 的命令，要求命令中所操作的 key 隶属于同一个分片，例如：rename <源 key> <目标 key>。
○集群版可通过 的方式支持。
○标准版使用单分片，所以满足这一要求。
●由于标准版/集群版内部自行维护分片数据，某些集群管理命令（例如 shutdown 等）不再适用。
●为了保证集群整体性能的最佳实践，某些线上不建议使用的命令（例如 keys 等）不提供支持。
以下的命令列表按功能分组展示，分组内按字母序排列。
说明：✓ 表示支持，✓slot 表示命令仅在不跨 slot 时支持，✗ 表示不支持，✗cluster 表示不适用于当前集群环境。
