Removing duplicate values (i.e., deduplicating).Reformatting for consistency (e.g., dates, row and column headings).Filtering missing, blank, or unusable values (e.g., null cells).The transform step is equivalent to data preparation and can involve: Refining the extracted data to ensure data quality, integrity, and compatibility with the destination source. ETL has three main processes: ExtractĮxporting raw data from various structured or unstructured sources, such as: In order for Business Intelligence (BI) software, such as Power BI and Tableau, to draw quick insights from data, it is essential to bring data together in an organized manner. Many organizations store data across multiple databases, and thus, use ETL. What is ETL?ĮTL is the process of combining data from multiple sources into a centralized database, such as a data warehouse, through three steps: Extract, Transform, and Load. As a result, ETL tools that help with data preparation, such as Tableau Prep, Microsoft Power Query, and Alteryx Designer, are becoming more popular than ever before. Data preparation is critical in producing accurate data analytics, but it is time consuming. However, a 2016 survey by CrowdFlower reveals 60% of surveyed data analysts spend most of their time cleaning and organizing data. If the flow isn't open on the web you will need to click Edit Flow to open your flow in editing mode, then either click Publish to publish the flow, or accept the prompt to publish the flow, then click Run Flow.When you look at a data analyst’s workflow, you might think most of their time is spent analyzing data. This will run your entire flow.Ĭlick on an Output step in your flow, then in the Output pane, click Run Flow. On the server, from the Explore page, right-click or Cmd-click (MacOS) More actions and select Run Now from the menu. In Tableau Prep Builder or on your server, open your flow.įrom the top menu, click Run to run the entire flow, or click the drop down arrow to select a flow output in the list.For more information, see Tableau Cloud Site Capacity (Link opens in a new window) in the Tableau Cloud help. In Tableau Cloud, the number of flow runs you can perform in a day is also limited by the site administrator. For more information, see Publish a Flow to Tableau Server or Tableau Cloud. If running flows in web authoring (version 2020.4 and later) the flow must be published to the server to run it, and you can't run another flow until the first flow is finished, even from a separate tab. You can run the whole flow or run the flow for a selected output. When you run flows manually, you can run one flow at a time. For information about scheduling your flow to run automatically, see Schedule a Flow Task (Link opens in a new window) in the Tableau Server help. Your server must include Data Management with Tableau Prep Conductor enabled.įor more information, see Tableau Prep Conductor in the Tableau Server (Link opens in a new window) or Tableau Cloud (Link opens in a new window) help. Using a schedule: In Tableau Server and Tableau Cloud you can schedule single flows to run or run multiple flows one after the other using linked tasks. For more information, see Flow Methods (Link opens in a new window) in the Tableau REST API help. REST API: Use the Flow and Flow Task REST API methods in Tableau Server to run flows.For more information, see Refresh flow output files from the command line (Link opens in a new window).

Command Line interface: If you don't have the Data Management you can run flows one at a time using the command line interface.

For more information, see Publishing flows in the Tableau Server (Link opens in a new window) or Tableau Cloud (Link opens in a new window) help. Flows on the web must be published before they can be run.

Manual: Run your flows manually any time in Tableau Prep Builder and on the web.

Run your flows manually, from the command line, using Tableau Server REST API flow methods, or using a schedule. For more information about using parameters in flows, see Run flows with parameters. You can also enter any optional parameter values or accept the current (default) value for the parameter. You must enter required parameter values. Note: Starting in version 2021.4.1, when you run flows that include parameters, you'll be prompted to enter parameter values.

All of your cleaning operations are applied to your full data set, resulting in a tidy, clean data set that you can now use to analyze your data. When you run the flow, all of your data (not just the data sample you might be working with) is run through your flow steps.

To generate your flow output you need to run your flow.

It is only required (with Tableau Prep Conductor enabled) if you plan to run your flows on a schedule. Important: Starting in version 2020.4.1, Data Management is no longer required to run flows manually on the web.
