However, we understand that you need to get your users connected to data today. So in this section we provide some guiding principles that you can use to make sound data access decisions as you roll out your shiny new Tableau Server. Extracts are great for enabling flow for your data analysts. When an extract is embedded in a workbook, all of the data is already available to Tableau Server, which stores the extract in a high-performance database. This generally results in good performance.
When users drag dimensions and measures, apply filters, and add visualizations, they see the results immediately. Because users are interacting with a snapshot of data and are not working directly with live data, the underlying source of data is not taxed as users analyze and visualize the data in Tableau. A note about using Tableau Server for warehousing: if the workbooks that people in your organization are using are really hitting a database hard with repeated queries for fresh data, you might be tempted to use Tableau Server to host extracts in an attempt to offload queries from the relational databases that people are using.
Generally, we don't recommend using extracts just to offload queries. This isn't an economical use of Tableau Server, which is designed for data analysis, not data warehousing. If you find that users are creating a lot of extracts because performance suffers when they use live connections to data, you should consider performance optimizations at the database rather than warehousing extracts on Tableau Server. Many data analysis scenarios require real-time data.
For example, finance operations that model transactions during trading hours usually require real-time data. Similarly, polling scenarios often require near real-time data freshness to provide quick analysis.
Generally, if the data analyses that your users are working on require data freshness that is measured in minutes or seconds, workbooks should be built using a live connection. Extracts can be refreshed frequently, but as we explained earlier, these updates can be processor-intensive and can slow the performance of the server.
At the same time, heavy use of live connections, especially with complex workbooks, can stress traditional databases. Therefore, you'll need to make sure that the Tableau Server processes are appropriately scaled for heavy use of live connections and your databases are up to the task of the query load from Tableau Server.
For information about tuning your server, see the Notifications, Monitoring, and Tuning chapter. Remember that the results from queries using live connections might be cached on the server.
Therefore, if you require true real-time data, make sure that you configure the cache to refresh more often, as we discussed earlier under Configure data connection caching. As we were saying earlier, you must decide whether you'll allow users to embed credentials in workbooks and data sources when they publish.
Your organization's security and privacy policy should dictate whether you allow users to embed credentials. If your organization enforces user-level permissions to databases, use a live connection for workbooks that connect to those databases. That way, users who interact with workbooks and data sources that require authentication will be prompted for credentials. People often ask which is faster: an extract or a live connection?
If you've read all the way through this, you understand that the answer is "it depends. In the end, the best way to answer this question is to build a workbook with a live connection to your database. In most cases, the performance differences are obvious as you build your workbook and view the results.
For more in-depth analysis, Tableau includes tools more information below that you can use to measure workbook performance on both Tableau Server and Tableau Desktop. Use those tools to profile the performance of the workbook that uses the live connection. When you've got that data, change the workbook to use an extract and then measure performance again. When you compare these results, a clear winner may emerge. If it's close, you can use the data to guide you in possible ways to improve performance.
For example, filtering to use only the subset of data that is required by the workbook might give you an obvious winner. Here are some links to the Tableau Help and the Tableau Server Help for information about how to run and interpret a performance recording:. Continue to Notifications, Monitoring, and Tuning. Connecting to Data Sources Version: Current. Think about data in Tableau Server terms If you use only Tableau Desktop, you manage all your own connections to data.
With Tableau Server available to your users, you can share data in several ways: Create and publish packaged workbooks that contain extracts created in Tableau Desktop. Think about optimizing data access and security In addition to thinking about ways you can share data access, you and your users must learn how to make the most efficient use of data.
As you become familiar with Tableau Server and learn how to optimize data access for your scenarios, your users will see these benefits: Performance. Before you begin We've written this chapter for Tableau Desktop champions who have been tasked with managing Tableau Server. You should be comfortable with the following terms and concepts: Data source. What do you need to do? This chapter of Tableau Server: Everybody's Install Guide discusses the three basic steps that you must perform in order to get started in your new role as a data administrator on Tableau Server: Provide access to data sources.
Deepen your understanding of the tradeoffs between using a live connection and an extract. Test the performance differences that might occur between a live connection and an extract. Provide access to data sources Providing access to data sources starts with understanding how various data sources handle authentication—that is, sign in.
Let users embed credentials or not As administrator, you can decide to let users embed passwords which are encrypted in the workbooks and data sources that they publish to the server. To enable or disable embedded credentials, sign in to Tableau Server.
This is a server-wide settings—the setting you make here applies to all workbooks on all sites. Set data source permissions Publishing data sources to Tableau Server lets people on your team provide centralized access to data. You can configure access by setting the following permission roles for the project or for individual data sources: Connector.
To set permissions on data sources in a project, follow these steps: Sign in to Tableau Server. Click site menu at the top of the page, and then select the site to work with. Under Actions , click Permissions. Select or add the user or group that you want to assign data source permissions to. Click Save. Get started on the right foot. Be in the know.
