Redis restore 命令

RESTORE key ttl serialized-value [REPLACE] [ABSTTL] [IDLETIME seconds] [FREQ frequency]

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.
(Redis 5.0 or greater).

For eviction purposes, you may use the IDLETIME or FREQ modifiers. See OBJECT for more information (Redis 5.0 or greater).

RESTORE will return a “Target key name is busy” error when key already
exists unless you use the REPLACE modifier (Redis 3.0 or greater).

RESTORE checks the RDB version and data checksum.
If they don’t match an error is returned.
