"MySQL 5.5官方手册提供了详尽的MySQL 5.5版本以及基于NDB CLUSTER 7.2的相关参考指南。手册涵盖了从5.5.28版本到MySQL Cluster 5.5.25a-ndb-7.2.8的所有功能。"
MySQL 5.5是MySQL数据库管理系统的一个重要版本,它引入了许多新特性,旨在提高性能、可扩展性和安全性。以下是一些关键知识点:
1. **InnoDB存储引擎增强**:MySQL 5.5中的InnoDB存储引擎得到了显著优化,包括支持更多的并行操作,如并行插入,提高了写入性能。此外,InnoDB还增加了自适应哈希索引,允许数据库根据工作负载自动创建和管理哈希索引,以提高查询速度。
2. **Full-text Search增强**:5.5版本引入了更强大的全文本搜索功能,包括对部分单词匹配的支持,改进的排序选项以及对多个字段的全文搜索。
3. **分区表**:在MySQL 5.5中,分区表功能得到了增强,允许用户根据需要对大型表进行分区,以改善查询性能和管理效率。
4. **复制改进**:MySQL 5.5的复制功能支持半同步复制,确保在主服务器上的事务提交之前,至少有一个从服务器接收到这些更改,从而提高了数据的一致性。
5. **性能提升**:MySQL 5.5包含了一些性能改进,例如,通过使用多线程查询执行来提高并发处理能力,以及更有效的内存管理,减少内存占用。
6. **存储过程和触发器**:手册中包含了关于创建和管理存储过程和触发器的信息,这些是数据库应用程序中常用的功能,用于实现复杂的业务逻辑和数据验证。
7. **安全性和权限**:MySQL 5.5增强了安全功能,包括更精细的权限控制,如GRANT和REVOKE语句的改进,以及更好的审计和日志记录能力。
8. **SQL语法**:手册详细介绍了SQL语言的使用,包括DML(数据操纵语言)、DDL(数据定义语言)和DQL(数据查询语言)等,以及优化查询性能的技巧。
9. **连接器**:MySQL 5.5支持多种编程语言的连接器,如Java的Connector/J,允许开发者在各种平台上轻松地与MySQL交互。
10. **安装与配置**:针对不同平台(如Linux/Unix、Mac OS X等)的安装和配置指南,帮助用户顺利安装和设置MySQL服务器。
11. **高可用性与可扩展性**:手册包含有关高可用性(HA)和可扩展性(Scalability)的指南,如如何设置主从复制、集群配置以及故障恢复策略。
12. **变更历史**:手册记录了MySQL 5.5自初始版本以来的所有变更,对于了解版本间的差异和改进至关重要。
MySQL 5.5官方手册是一部全面的参考资料,无论对于数据库管理员、开发人员还是初学者,都是学习和使用MySQL 5.5不可或缺的工具。
