    The standard and cluster architectures of Redis 4.0, 5.0, 6.2, and 7.0 support the following commands: touch, restore, object, unlink, wait, dump, del, scan, exists, expire, expireat, keys, type, move, ttl, persist, pexpire, pexpireat, pttl, randomkey, rename, renamenx, and sort.
    Only Redis 6.2 and 7.0 support the copy and object help commands.
    In cross-slot scenes for the cluster architecture, the del and exists commands are supported, while unlink, rename, and renamenx are not supported.
    New commands supported in the Redis 7.0: sort_ro, expiretime, and pexpiretime.
