问题 I'm having the following issue: I have an SSIS package that connects to an oracle DB using Attunity Connection Manager. It does connect in my local pc (to a remote oracle db server) and extracts and all, seems to work. The problem comes when I load it to SQL server to be run as a Job. I have ran other jobs so the setup is proper, set to run with 32 bit runtime, loading as a file system type. but when I try to execute the job it gives the following error: Executed as user: username.

问题 This is my second attempt at understanding how to pass arguments to dependencies in Luigi. The first one was here. The idea is: I have TaskC which depends on TaskB , which depends on TaskA , which depends on Task0 . I want this whole sequence to be exactly the same always, except I want to be able to control what file Task0 reads from, lets call it path . Luigi's philosophy is normally that each task should only know about the Tasks it depends on, and their parameters. The problem with this

问题 I've tried reading the Wikipedia article for "extract, transform, load", but that just leaves me more confused... Can someone explain what ETL is, and how it is actually done? 回答1: ETL is taking data from one system (extract), modifying it (transform) and loading it into another system (load). And not necessarily in that order. You can TEL, or ELT. Probably not LTE though. :-) It's a catch-all name for any process that takes data from one system and moves it to another. 回答2: ETL is commonly
