key-to-disk

基本解释

So you only have to remember one single master password or insert the key-disk to unlock the whole database.
因此，您只需记住一个主密码或插入密钥盘就能解锁整个密码数据库。
A key-value store is basically a hash table on disk, so the location of a piece of data can be guessed without having to consult an index.
键值存储从基本上说就是磁盘上的哈希表，因此在无需借助索引的情况下可以猜测一块数据的位置。
This means that when we create auto-increment primary key and insert records to a table, our sessions records are grouped together and saved sequentially on the disk.
InnoDB会根据主键将所有数据分组。这意味着当我们使用自增长主键并向表插入记录时，会话记录会被组到一起，顺序地存储在磁盘上。
