redis_cron redis_cron是Redis一个基于cron表达式的简单作业调度程序,它在redis中作为模块运行。 它使用与常规cron相似的语法,并允许您直接在redis上调度redis命令。 这个项目的灵感来自PostgreSQL扩展 。 由于redis命令只能在redis中一次由一个线程运行,因此redis_cron在单个线程中按顺序运行计划的作业。 安装 $ cargo ...
pg_cron 是由 citusdata 公司开发的一个 PostgreSQL 定时任务插件(类似于 Oracle 中的 DBMS_SCHEDULER)。pg_cron 作为一个后台工作进程运行,使用类似 cron 的编辑语法,允许直接在数据库中执行定时任务。例如: -- 每周六 3:30am (GMT) 删除历史记录SELECT cron.schedule('30 3 * * 6', $$DELETE FROM event...
I find pg_cron to be super useful. And some have gone so far to say that it’s “really cool” to have the scheduler within the database, and tied to the data itself. We’re happy to see that pg_cron has gotten significant contributions f...
pg数据库需要定期维护,即所谓的清理。许多情况下,让autovacuum守护程序执行vacuum就足够了,一些DBA会希望用手动管理的VACUUM命令来补充或替换autovacuum(通常利用cron或Task Scheduler执行脚本)。为了正确设置手动管理的vacuum,必须理解接下来几个小节中讨论的问题。依靠自autovacuum的管理员也可阅读帮助理解和调整autovacuum。

Traditional job schedulers, such as cron or pg_cron, can either launch scripts or execute SQL. It can be very hard to combine those tasks, topping that off with problems of modularization. pg_timetable helps you to run those operations. “Base tasks” can be combined in a flexible way ...
2018-05-21 20:21:36.164 UTC [10109] LOG: pg_cron scheduler started That seems fine. Once your job is scheduled to run there should be some error if it is unable to connect. cosmindidis commented Jun 7, 2018 For what is worth: my v1.1 installation (built from sources) has the 'ac...
