Neo4j 2.1.2 发布,此版本是个维护版本,主要是 bug 修复和系统改进,建议每位用户都更新。
值得注意的更新内容如下:
Cypher uses indexes for resolving WHERE clauses which use the IN operator
Resolves a recovery issue, where multiple forced-restarts in a row, without clean shutdown or log rotation in between, could lead to some transactions not being replayed on recovery
Neo4j Browser now defaults to long intervals of heartbeat pings to server, lowering CPU use and network traffic
Corrects a critical issue that can occur during migration from previous Neo4j releases, which could lead to incorrect record structures if the previous store had a large volume of deleted data
更多更新内容请看发行说明。
Neo是一个网络----面向网络的数据库----也就是说,它是一个嵌入式的、基于磁盘的、具备完全的事务特性的Java持久化引擎,但是它将结构化数据存储在网络上而不是表中。网络(从数学角度叫做图)是一个灵活的数据结构,可以应用更加敏捷和快速的开发模式。
你可以把Neo看作是一个高性能的图引擎,该引擎具有成熟和健壮的数据库的所有特性。程序员工作在一个面向对象的、灵活的网络结构下而不是严格、静态的表中----但是他们可以享受到具备完全的事务特性、企业级的数据库的所有好处。
