入门
当
Tableau Prep Builder
首次发布时，许多人终于有机会建立自己的数据准备流程，
以减轻清理和合并数据集过程中烦琐和重复性的任务，从而实现有价值的数据分析。
一旦创建了流程，每次用户点击
Prep Builder
中的运行图标时，它都会被重新运行。
对于单个数据流来说，这很简单；但对于大量不同的数据源来说，它往往涉及多项
准备工作。此时就是
Tableau Prep Conductor
的用武之地：你可以在
Prep Builder
中
建立一个流程，但在需要时将其安排在
Prep Conductor
上运行。
本章将介绍何时可能需要使用
Tableau Prep Conductor
，它提供的功能，以及如何实
际使用
Prep Conductor
。

何时使用
Tableau Prep Conductor
Prep Conductor
主要用于按照设定的时间表运行上传的流程。这样做有很多好处：
•
流程不需要每天手动打开和运行。
•
执行过程中的错误会被记录在服务器上，而不是仅仅记录在个人的计算机上，
因此如果流程失败，你可以更容易地排除故障。
• Prep Conductor
很可能运行在一台比数据分析者的计算机拥有更多处理资源的计
算机上，所以准备流程会运行得更快。
• Prep Conductor
作为所有流程的中央存储库，有利于流程的重用。
