用的最广泛的Operator,在airflow1.0的时候,定义pythonOperator会有两部分,一个是operator的申明,一个是python函数。这时候函数传参是需要用到op_args 或者op_kwargs或者templates_dict 代码语言:javascript 代码运行次数:0 运行 AI代码解释 def_get_data(output_path,**cont
Deferrable Operators是sensor operator的替代品,其本质是应用了python的异步机制,有一个trigger process,当其符合特定条件后,就会将任务调度起来。如果用原生的Sensor Operator,并行150个任务的时候,会占用13G左右的内存,并且消耗CPU在无意义的轮询中;而用新的Deferrable Operators之后,额外使用的内存非常少只有几百兆。 ...
点击"Trigger DAG"图标,Airflow会触发一次批量执行,这种人为干预触发的批量,在"Tree View"页面里,其run_id上会显示以manual开头的字符串,表示该批次是手工触发执行。手工Trigger的Dag Run,Started参数与run_id参数比较一致,只是稍稍晚了几秒钟。 (图11) 手工Trigger的批次,和Airflow调度器自动Trigger的批次一样,也是...
但是除了“执行成功all_success”这个条件以外,还有其他的trigger rule,例如one_success, one_failed(至少一个上游失败),none_failed ,none_skipped DAG在配置的时候,可以配置同时运行的任务数concurrency,默认是16个。这个16,就是task slot,可以理解为资源,如果资源满了,具备运行条件的task就需要等待。 定义DAG的方式...
