RESTORE
RESTORE key ttl serialized-value [REPLACE] [ABSTTL] [IDLETIME] [FREQ]
- Available since
- 2.6.0
- Time complexity
- O(1) to create the new key and additional O(N*M) to reconstruct the serialized value, where N is the number of Redict objects composing the value and M their average size. For small string values the time complexity is thus O(1)+O(1*M) where M is small, so simply O(1). However for sorted set values the complexity is O(N*M*log(N)) because inserting values into sorted sets is O(log(N)).
- ACL categories
- @keyspace, @write, @slow, @dangerous
Create a key associated with a value that is obtained by deserializing the
provided serialized value (obtained via DUMP
).
If ttl
is 0 the key is created without any expire, otherwise the specified
expire time (in milliseconds) is set.
If the ABSTTL
modifier was used, ttl
should represent an absolute
Unix timestamp (in milliseconds) in which the key will expire.
For eviction purposes, you may use the IDLETIME
or FREQ
modifiers. See
OBJECT
for more information.
!RESTORE
will return a “Target key name is busy” error when key
already
exists unless you use the REPLACE
modifier.
!RESTORE
checks the RDB version and data checksum.
If they don’t match an error is returned.
Examples #
redict> DEL mykey
0
redict> RESTORE mykey 0 "\n\x17\x17\x00\x00\x00\x12\x00\x00\x00\x03\x00\
