- 背景介绍：
DBA 经常需要维护索引碎片保证查询效率，在维护索引的同时也会不可避免的造成部分语句的暂时block。出于工作需要，编写了这个简单的索引维护逻辑。
- 环境介绍
sql server 2016 单节点 / alway on
- 维护逻辑介绍
入下图所示：1.生成待维护的索引列表（monitor.dbo.dba_index_fragment）
2.启动job DBA_index_main 作为主进程 调用job DBA_index_optimize_01/02/0* 并行维护索引。可根据需要创建不同数量的job DBA_index_optimize_0* 来调节并行数量缩短index维护时间。
优缺点介绍：可以自动发现跳过长时间block其他session,继续维护队列内的下一个index. 可以根据需要调节并行维护的进程数量。该逻辑仅仅维护index 没有做统计信息更新
创建完成后默认会有3个job入下图所示

- 以下内容介绍如何根据需要个性化定制：
1. 维护时间窗口设置：
2.只维护特定的db， 特定的table， 获取索引碎片参数，历史记录保存时间
3. 修改procedure [updba_index_fragment] 逻辑过滤不需要维护的索引
