On 2013年06月5日, in soft, by netoearth

MongoDB 2.4.4发布. 2013-06-04 之前版本是2013-04-24发布的2.4.3。修正大量bug以及几个增强。 其他产品线2.2.4 2.0.9 开发版2.5.0。

MongoDB是一个介于关系数据库和非关系数据库之间的产品, 是非关系数据库当中功能最丰富,最像关系数据库的。他支持的数据结构非常松散,是类似json的bjson格式,因此可以存储比较复杂的数据类型。 Mongo最大的特点是他支持的查询语言非常强大,其语法有点类似于面向对象的查询语言,几乎可以实现类似关系数据库单表查询的绝大部分功能,而且还支持 对数据建立索引。

它的特点是高性能、易部署、易使用,存储数据非常方便。主要功能特性有:

  • 面向集合存储,易存储对象类型的数据。
  • 模式自由。
  • 支持动态查询。
  • 支持完全索引,包含内部对象。
  • 支持查询。
  • 支持复制和故障恢复。
  • 使用高效的二进制数据存储,包括大型对象(如视频等)。
  • 自动处理碎片,以支持云计算层次的扩展性
  • 支持RUBY,PYTHON,JAVA,C++,PHP等多种语言。
  • 文件存储格式为BSON(一种JSON的扩展)
  • 可通过网络访问

完全改进:

  • [SERVER-9542] – Incorrectly coded chunk/shard version comparison
  • [SERVER-9578] – mongos dies on SIGUSR1 instead of rotating logs
  • [SERVER-9618] – server8070.js failing intermittently across OS X builders
  • [SERVER-9621] – closeall.js failing on new windows 32-bit builder
  • [SERVER-9638] – no_empty_reset.js failing
  • [SERVER-9647] – Query using compound 2dsphere index with additional descending field can block indefinitely
  • [SERVER-9649] – No public role grants writebacksQueued
  • [SERVER-9658] – Reduce frequency of debug message “we think data is in ram”

Improvement

  • [SERVER-4739] – Race condition in log rotation (was: SIGUSR1 should set a flag rather than doing rotation)
  • [SERVER-9636] – Display chunk version, not memory address, in non-default log line

Task

  • [SERVER-8813] – Migrate to Cyrus SASL2 library for sasl authentication.

Sub-task
