airflow 是能进行数据pipeline的管理,甚至是可以当做更高级的cron job 来使用。现在一般的大厂都说自己的数据处理是ETL,美其名曰 data pipeline,可能跟google倡导的有关。airbnb的airflow是用python写的,它能进行工作流的调度,提供更可靠的流程,而且它还有自带的UI(可能是跟airbnb设计主导有关)。话不多说,先放两...
PythonCoding Fundamentals Python provides full-fledged support for implementing your own data structure using classes and custom operators. In this tutorial, you will implement a custom pipeline data structure that can perform arbitrary operations on its data. We will use Python 3. ...
Once we receive the messages, we’re going to process them in batches of 100 elements with the help of Python’s Pandas library, and then load our results into a data lake. The following diagram shows the entire pipeline: The four components in our data pipeline each have a specific role...
