摘要

Although log-structured merge trees (LSM-trees) are commonly adopted in many NoSQLs as they can significantly improve the write performance in updating a database, most of the proposed LSM-trees are concentrated on storing a single version of data. On the other hand, in many Internet of Things (IoT) applications, it is important to maintain the old versions of data in addition to the latest versio...
