MySQL 5.5 版本发布

by Alpha 17. December 2009 14:08
  • 支持半同步复制,这个是从早期google 的semi-sync patch转过来的,能够做到master-slave的半同步复制
  • 集成Innodb plugin 1.0.6
  • 支持 SQL 标准 SIGNAL 和 RESIGNAL 语句
  • 增强XML功能,支持 LOAD XML 语句
  • 可通过 ALTER TABLE ... TRUNCATE PARTITION 来删除某个表在某个分区上的所有数据
  • 增加了 TO_SECONDS 函数
  • 新的 partition语法
  • Key caches are now supported for indexes on partitioned MyISAM tables, using the CACHE INDEX and LOAD INDEX INTO CACHE statements
这个版本还不适合用在正式环境。想想以后也许可以用mysql mmm + mysql 5.5提供可用性更好的服务,前提是它已经足够稳定,或者是percona版本?
