spring quartz 12张表的效能作用

JobStore 是基于 JDBC 的，它需要一个数据用于 Scheduler 信息的持久化。Quartz 需要创建 12 张数据库表。表的名字和描述在表 6.1 中列出。

表 6.1. Quartz 需要下列表用于所有的 JDBC 的持久性 JobStore

| 表名 | 描述 |
| QRTZ_CALENDARS | 以 Blob 类型存储 Quartz 的 Calendar 信息 |
| QRTZ_CRON_TRIGGERS | 存储 Cron Trigger，包括 Cron 表达式和时区信息 |
| QRTZ_FIRED_TRIGGERS | 存储与已触发的 Trigger 相关的状态信息，以及相联 Job 的执行信息 |
| QRTZ_PAUSED_TRIGGER_GRPS | 存储已暂停的 Trigger 组的信息 |
| QRTZ_SCHEDULER_STATE | 存储少量的有关 Scheduler 的状态信息，和别的 Scheduler 实例(假如是用于一个集群中) |
| QRTZ_LOCKS | 存储程序的非观锁的信息(假如使用了悲观锁) |
| QRTZ_JOB_DETAILS | 存储每一个已配置的 Job 的详细信息 |
| QRTZ_JOB_LISTENERS | 存储有关已配置的 JobListener 的信息 |
| QRTZ_SIMPLE_TRIGGERS | 存储简单的 Trigger，包括重复次数，间隔，以及已触的次数 |
| QRTZ_BLOG_TRIGGERS | Trigger 作为 Blob 类型存储(用于 Quartz 用户用 JDBC 创建他们自己定制的 Trigger 类型，JobStore 并不知道如何存储实例的时候) |
| QRTZ_TRIGGER_LISTENERS | 存储已配置的 TriggerListener 的信息 |
| QRTZ_TRIGGERS | 存储已配置的 Trigger 的信息 |

--
-- A hint submitted by a user: Oracle DB MUST be created as "shared" and the
-- job_queue_processes parameter must be greater than 2
-- However, these settings are pretty much standard after any
-- Oracle install, so most users need not worry about this.
--
-- Many other users (including the primary author of Quartz) have had success
-- runing in dedicated mode, so only consider the above as a hint ;-)
