Redis SETEX 命令

Created2023-06-04|Updated2024-12-04|Redis教程

|Post Views:

从 Redis 2.6.12 版本开始，此命令被标记为已废弃。
在迁移或编写新的代码时，可以使用带有 EX 参数的 SET 命令替代。

语法

1	SETEX key seconds value

可用版本

≥ 2.0.0

时间复杂度

$O(1)$

ACL类别

@write, @string, @slow

设置 key 以保存字符串值，并将 key 设置为在给定的秒数后过期。此命令等效于：

1	SET key value EX seconds

当秒数无效时，返回错误。

返回值

如果正确执行，则返回 OK。

示例

redis> SETEX tt_key 1000 "JOHNSON"
OK
redis> TTL tt_key
(integer) 1000
redis> GET tt_key
"JOHNSON"

（END）

Introduction to Redis Bitmaps

Bitmaps are not an actual data type, but a set of bit-oriented operations defined on the String type which is treated like a bit vector. Since strings are binary safe blobs and their maximum length is 512 MB, they are suitable to set up to 2^32 different bits. You can perform bitwise operations on one or more strings. Some examples of bitmap use cases include: Efficient set representations for cases where the members of a set correspond to the integers 0-N. Object permissions, where each bit...

Redis HyperLogLog PFMERGE Command

The Redis PFMERGE command merges multiple HyperLogLogs into a single HyperLogLog. The cardinality estimate of the resulting HyperLogLog is calculated by taking the union of all the given HyperLogLogs. SyntaxThe basic syntax of the PFMERGE command is as follows: 1PFMERGE destkey [sourcekey [sourcekey ...]] The command merges multiple HyperLogLog values to approximate the cardinality of the union of the observed sets. The result is stored in a destination variable, which is created if it doesn’...

Redis Set SINTER Command

The Redis SINTER command returns the members of the set resulting from the intersection of all the given sets. Keys that do not exist are considered to be empty sets. With one of the keys being an empty set, the resulting set is also empty (since set intersection with an empty set always results in an empty set). For example: 1234key1 = {a,b,c,d}key2 = {c}key3 = {a,c,e}SINTER key1 key2 key3 = {c} SyntaxThe basic syntax of the SINTER command is as follow...
