In Tcl, asynchronous I/O is managed through thefileeeventcommand, which uses the same event loop used by Tk, timers, etc. It's fully detailed in thereference manual. It's used extensively in other parts of Tcl,

灵活性:可以定义复杂的响应逻辑,通过PL/pgSQL、PL/Tcl、PL/Perl等过程语言来实现。 事件触发器的使用场景 审计和日志记录:记录所有DDL操作的日志,以便进行审计或回滚。 安全策略实施:防止未经授权的DDL更改,或确保在更改前满足某些条件。 自动化任务:在数据库达到特定条件时自动执行维护任务,如清理日志、备份等。
