  条理、逻辑、语言都极度舒服，尤其是每一章都引用了非常多的参考文献，这些参考文献大多数都值得一读。算是分布式系统工程概述性方面写得最好的书籍！

  真是一本好书，分析问题，解决问题，理论联系实践。有时间要二刷。PS：最后一章最后一节比一般技术书籍真是不知道要高到哪里去。2019.12.2 二刷完毕，感觉依然那么棒！

  However, in the move to dis‐ tributed (replicated and partitioned) databases, many systems have abandoned them, claiming that transactions are too expensive in terms of performance and availability, and asserting that eventual consistency is inevitable in a scalable system. There is some truth in that statement, but it is overly simplistic, and we will develop a more nuanced view over the course of the rest of this book.

  Index-range locksUnfortunately, predicate locks do not perform well: if there are many locks by active transaction, checking for matching locks becoms time-consuming. For that reason, most databases with 2PL actually implement index-range locking (also known as next-key locking), which is a simplified approximation of predicate locking.an approxinmation of the search condition is attached to one of the indexes. Now, if anohter transaction wants to insert, update, or delete a booking for the same room and/or an overlapping time period, it will have to update the same part of the index. In the process of doing so, it will encounter the shared lock, and it will be forced to wait until the lock is released.
