The best Redis key (key) Tutorial In 2024, In this tutorial you can learn Redis keys command,
Redis key commands for managing redis keys.
The basic syntax Redis key command is as follows:
redis 127.0.0.1:6379> COMMAND KEY_NAME
redis 127.0.0.1:6379> SET w3bigkey redis OK redis 127.0.0.1:6379> DEL w3bigkey (integer) 1
In the example above is aDEL command,w3bigkey is a bond. If the key is removed successfully, command execution output(integer) 1, otherwise the output (integer) 0
The following table shows the basic commands associated with the Redis key:
No. | Command and description |
---|---|
1 | DEL key This command is used to delete key when the key presence. |
2 | DUMP key The sequence of a given key, and return the serialized value. |
3 | EXISTS key Checks if the given key exists. |
4 | Key the EXPIRE seconds The For a given key set an expiration time. |
5 | EXPIREAT key timestamp EXPIREAT EXPIRE similar role and are used to set the expiration time for the key. Except that time parameters EXPIREAT accepted command is a UNIX timestamp (unix timestamp). |
6 | PEXPIRE key milliseconds Setting key expiration time in milliseconds. |
7 | PEXPIREAT key milliseconds-timestamp Setting key expiration timestamp (unix timestamp) in milliseconds |
8 | KEYS pattern Find all match a given pattern (pattern) of the key. |
9 | MOVE key db The key to move the current database to a given database db them. |
10 | PERSIST key Remove key expiration time, key will endure. |
11 | PTTL key In milliseconds return key remaining expiration time. |
12 | TTL key In seconds, return the given key remaining time to live (TTL, time to live). |
13 | RANDOMKEY From the current database returns a random key. |
14 | RENAME key newkey Modify the name of the key |
15 | RENAMENX key newkey Only when newkey does not exist, the key renamed newkey. |
