数据抽取是ETL流程的起始阶段，通常涉及从各种来源获取原始数据。这可能包括访问外部API、读取CSV文件、数据库查询等。Python的requests库用于HTTP请求，pandas库则能轻松读取和处理CSV文件。转换（Transform）数据转换阶段涉及到对原始数据进行清洗、格式化和预处理。Pandas库提供了丰富的数据操作功能，如数据筛选、排序、聚合...
pipeline.add(sub_pipeline, ['ping_localhost']) pipeline.add(Task(id='sleep', description='Sleeps for 2 seconds', commands=[RunBash('sleep 2')]), ['sub_pipeline']) 可以看到,Task包含了多个commands,这些 commands会用于真正地执行动作。 而pipeline.add 的参数中,第一个参数是其节点,第二个参数...

Now, you can easily create your processing pipeline, and let Pathway handle the updates. Once your pipeline is created, you can launch the computation on streaming data with a one-line command: pw.run() You can then run your Pathway project (say,main.py) just like a normal Python script...
