MapDB 同步读写示例 - Don't forget your dreams!
http://www.xn--7qv19ae78e.cn/utils/2016-01/mapdb-write-read-sync.html
Don't forget your dreams! MapDB 是一个快速、易用的嵌入式Java数据库引擎. 最主要的特点之一就是支持磁盘存储,直接把内存中的Hash Map同步写入到磁盘. 另外特别惊喜的是它支持ACID事务,MVCC隔离, 且有全职的开发者支持. 看完官方的文档与示例后,基本上可以确定它符合业务场景的使用要求.另外发现官方正在重构3.x的版本, 但应该不会这么快发布吧.用google搜索了下关于MapDB的使用案例, 也不是很多. 可能是本来官方的文档就齐全有关吧,API也不复杂,跟着官方的文档走一遍就可以上手了. 动手测试了简单的示例后, 突然冒出一个疑问, 如何实现同时操作磁盘上的一个数据库, 以及同一个HashMap呢? 这里需要明白的, MapDB存储到磁盘上的数据库文件,并非只是存放了一个HashMap, 这有点类似数据库里可以有多张表的概念相同. 那么数据库是可以支持多连接的, MapDB是否也同样支持呢?

Mercredi 28 mai 2014. Indexing keys and values in MapDB. Is a high performance pure java database, it provides concurrent collections (Maps, Sets and Queues) backed by disk storage or off-heap memory. It provides a powerful mechanism to synchronize collections that can be used to build multiple indexes on a primary collection. Follows is an example showing how to index keys and also values of main collection. 1 define a serializable class. 2 Define a map of persons by id. 3 Define a gender-based index.

Lundi 18 août 2014. Comparison between caching systems for Java. Servers are getting more and more powerful with a lot of RAM (up to hundred to thousands of giga bytes). However, it is still not possible to use most of the available capacity directly in java applications due to inherent limitations of the GC (Garbage Collector) on JVM that may pause the application for a long time (even up to many minutes) to move objects between different generations. 1 Infinispan (JBoss Data Grid Platform).
