实验证明,该方案不仅能节省存储空间,而且能实现基于疵病特征的随机读取和再现。
The experiment showed that this solution could not only save the storage space, but also implement random read and reconstruction in defect feature level.
当然,底层操作系统可能会随机读取数据的文件被打开时,为了节省时间,但那是你控制之外的所以实际上没关系。
Of course the underlying operating system might decide to speculatively read data when the file is opened, to save time later, but that's outside your control so in effect it doesn't matter.
使用该算法避免了对同一引用实例或是位于同一数据块上不同记录的重复读取,并将对磁盘的随机读取方式转变为按列表预取的读取方式。
It can avoid reading the same reference instance and records in the same data block repeatedly. Meanwhile it can convert random reading disk into doing by table.
