Tableau Prep shifts this paradigm by bringing self-service data preparation to everyone, rather than just those with specialized skills. ![]() The Harvard Business Review even found that many analysts spend 80% of their time preparing their data, spending only 20% of time for analysis. From working with customers over the years, we hear, anecdotally, that cleaning data for analysis is a cumbersome process. However, to make better use of the horizontal scalability and fault tolerance of Airflow and Docker, deploy with Docker Swarm or Kubernetes.In our role as solution engineers at Tableau, we get hands-on with customers every day, and get to see how companies - big and small - use Tableau Prep to clean and prepare their data. docker compose on a single machine is great for Development and Test environments where containers can be quickly spun up and linked.To run in production, you would want to modify the airflow.cfg file to enable your desired authentication method. By default, Tableau Prep Orchestrator does not use authenticaion.Everything is preinstalled and templated to further automate and extend your Tableau environment as more needs arise. This can be used to manage backups or automate permissions and licensing on your Tableau Server. Add new DAGs or alter current ones to add any other workflows to run in tandem to Prep Flows.Edit the Airflow config and dockerfiles to customize the implementations of Airflow and how it is deployed.Edit each DAG to change timezone, scheduled execution times, and how to handle task failures.One of the bigget benefits to Tableau Prep Orchestrator is it's also a full intance of Airflow with limitless was to customize and extend its functionality. You can view a short video of the process here: Customizations In the DAG graph view, press the refresh button in the top-right corner periodically to watch Airflow run each Flow on Tableau and monitor its timing and progress. Toggle it to "On" as well and click the linked DAG name to navigate to the graph view. Refresh your browser and see the newly created "orchestrate_prep_flows" DAG. This gather the Flows metadata from Tableau and use it to create the orchestration DAG. Toggle the DAG to "On" and wait a few seconds for it to run. Open a browser window and navigate to to start using Tableau Prep Orchestrator docker compose -f docker-compose-LocalExecutor.yml up -d.docker run -d -p 8080:8080 airflow tableau-prep-orchestrator.Run with docker run (Sequential Executor) Open terminal or cmd and navigate to the directory where you cloned the GitHub Repo then run the commands below that correspond to the setup you would like. # Tableau Server API Info tableau-base-url: " " tableau-site: "my-tableau-site " tableau-username: " tableau-password: "super-secret-password " # leave blank to gather flows from all projects projects-to-refresh-from: Otherwise, leave empty and all Flows on the site will be pulled in for orchestration. If you only want to orchestrate Tableau Prep Flows in certain projects, fill out the projects-to-refresh-from section with a list of projects. Fill out tableau-config.yml file with your Tableau Server/Online connection info.Clone this repo onto your local machine.Setup Setup Dockerīefore you can use Tableau Prep Orchestrator, you will need to install Docker. Any changes made are automatically added at a configurable interval (every 5 min by default) and will integrate into your existing DAG with no manual intervention required. yml file with your Tableau Server login info and spinning up this Docker container (setup instructions below), your Prep Flows are automatically profiled and an Airflow DAG is generated with all dependencies and order of operations handled for you. ![]() It combines Airflow with Tableau's Metadata and REST APIs to create a standalone server for scheduling, running, and managing dependencies around Tableau Prep Flows published to Tableau Server. Tableau Prep Orchestrator is an opinionated docker deployment of Apache Airflow that has been preconfigured to work with Tableau Server/Online and acts as an open-source alternative to Tableau Prep Conductor.
