key operation method

Method list

Method name Parameter Description Notes
del $key Delete a key
dump $key Serialization
exists $key Whether the query exists
expire $key, $expireTime = 60 Set the expiration time (in seconds) for the key
pExpire $key, $expireTime Set the expiration time (in milliseconds) for the key
expireAt $key, $expireTime Set the expiration time of the key in UNIX timestamp format The function of expireat is similar to that of expiration, which is used to set the expiration time for the key. The difference is that the time parameter accepted by the expireat command is UNIX timestamp. At, as the name suggests, will expire at some point in the future
keys $pattern Match key
move $key, $db Move key Cluster mode cannot be used
persist $key Remove the expiration time of the key
pTTL $key Return millisecond expiration time
ttl $key Return expired time
randomKey Randomly return a key
rename $key, $new_key Modify the name of the key Cluster mode cannot be used
renameNx $key, $new_key Modify the key name when newkey does not exist Cluster mode cannot be used
type $key Returns the data type stored by the key
