您可以从一个简单的表开始,该表具有以下用于存储计划的通用模式 (PostgreSQL)。考虑称为“作业”的调度运行的每个实例。
CREATE TABLE Schedule (
    id SERIAL UNIQUE,                      -- unique identifier for the job
    name varchar(64) NOT NULL,             -- human readable name for the job
    description text,                      -- details about the job
    schedule varchar(64) NOT NULL,         -- valid CRON expression for the job schedule
    handler varchar(64) NOT NULL,          -- string representing handler for the job
    args text NOT NULL,                    -- arguments for the job handler
    enabled boolean NOT NULL DEFAULT TRUE, -- whether the job should be run
    created_at timestamp NOT NULL,         -- when was the job created
    updated_at timestamp NOT NULL,         -- when was the job updated
    start_date timestamp,                  -- job should not run until this time
    end_date timestamp,                    -- job should not run after this time
    last_triggered_at timestamp,           -- when was the job last triggered
    meta json                              -- additional metadata for the job 
);
