CLUSTER KEYSLOT key

自3.0.0起可用。

时间严重年夜度:华夏棋牌 O(N)其中N是密钥中的字节数

华夏棋牌前往一个整数,用于标识指定密钥散列到的散列槽。该敕令主要用于调试和测试,由于它经由历程 API 地下了哈希算法的底层 Redis 完成。此敕令的示例用例:

华夏棋牌1. 客户端库可以应用 Redis 来测试他们自己的散列算法,天生随神秘钥并用它们的当地完成和应用 Redis CLUSTER KEYSLOT 敕令散列它们,然后检查效果能否类似。

华夏棋牌2. 人类可以应用此敕令来检查甚么是散列槽,然后是联系关系的 Redis 集群节点,担负给定的密钥。

示例

> CLUSTER KEYSLOT somekey11058> CLUSTER KEYSLOT foo{hash_tag}(integer) 2515> CLUSTER KEYSLOT bar{hash_tag}(integer) 2515

请重视,该敕令完成了完全的散列算法,网罗对散列标签的支持,这是 Redis Cluster 密钥散列算法的特殊属性,用于哈希中央的内容{}假定在密钥称谓内找到这样的形式,以便强迫多个键由统一个节点处置赏罚赏罚。

前往值

整数回复:散列槽号。
