Looker Labs features are new, in-progress features, whose details may change over time. They are split into two categories:
- Beta: These features are expected to remain in the product, and errors are expected to be resolved at some point. However, these features may change in detail, and errors may not be fixed with the same speed as with normal features. The list of current beta Labs features is in Beta Features, below.
- Experimental: These features may or may not remain in the product, and errors may or may not be corrected. They are intended to let you know what Looker is thinking about and to get your feedback. The list of current experimental Labs features is in Experimental Features, below.
You can choose to use these features or leave them disabled. You’ll see a list of these features on the Labs page in the General section of the Admin menu. The list of available features may vary, so the feature names and descriptions are blurred in this example:
Each feature has a short description underneath it explaining the functionality that it adds to or changes in Looker. If you would like more details about a feature, check out the Community Forums, which sometimes have more detailed descriptions, or reach out to Looker Support.
Enabling and Disabling Labs Features
To enable or disable a feature, click the switch next to the feature name.
Use caution when disabling a Labs feature. If users or developers have relied on the feature to create a certain behavior, disabling the feature will break that functionality.
Current Labs Features
Looker supports the following experimental and beta Labs features.
Beta Labs features are expected to remain in the product, and errors are expected to be resolved at some point. However, their details may change, and errors may not be fixed with the same speed as they would be for normal features.
Allows users to cross-filter dashboards (beta). Cross-filtering makes it easier and more intuitive for dashboard viewers to interact with a dashboard’s data and understand how one metric affects another. You must also enable the New Dashboard Experience Labs feature.
Cross-filtering is available only for dashboards (beta); it is not available for original dashboards.
Database Connection Pooling
Enables the use of preconfigured database connection pools on the Amazon Redshift, PostgreSQL, and Snowflake database dialects.
This option lets Looker use pools of connections through the JDBC driver. Database connection pooling enables faster query performance; a new query does not need to create a new database connection but can instead use an existing connection from the connection pool. The connection pooling capability ensures that a connection is cleaned up after a query execution and is available for reuse after the query execution ends.
The Extension Framework switch enables the integration of web applications built using the Looker extension framework and deployed through the Looker Marketplace. You must enable the Marketplace and Local Project Import Labs features to install and use Marketplace extensions.
The Looker Marketplace is a central location for finding, deploying, and managing any type of Looker content, such as Looker Blocks, applications, visualizations, and plug-ins. You must enable the Local Project Import Labs feature to install packages from the Marketplace. This Labs feature is enabled by default.
Sandboxed Custom Visualizations
Supports custom visualizations rendered in a sandbox.
Custom visualizations are a community-supported effort. Looker’s support team does not troubleshoot issues relating to custom visualizations or your custom visualization code. For tracking and closing out bugs, please use GitHub issues in the custom visualization’s repository, or visit Looker’s Community Forums for how-to articles, conversations, and tips regarding custom visualizations.
For more information about custom visualizations, see the Visualizations documentation page. However, Looker recommends exploring the visualizations available from the Looker Marketplace.
To enjoy full functionality of this Labs feature, admins for customer-hosted deployments should should be sure they have installed the appropriate version of the Chromium renderer.
SQL Runner Vis
Adds the ability to visualize ad hoc queries from SQL Runner.
System Activity Model
New in Looker 7.16, users with the
see_system_activity permission can use the System Activity model, dashboards, and Explores to view and explore the Looker internal database without having to enable a Labs feature.
Upgraded Explore Field Picker
When this feature is enabled, an Explore will display an upgraded field picker with a smarter search capability, easy view and management of selected fields, and user experience improvements.
When Visual Drilling is turned off, the drill overlay always displays the data table.
When Visual Drilling is enabled, the drill overlay selects the best visualization based on the underlying data, which may be a table visualization or some other visualization type. Or, with Visual Drilling enabled, a drill visualization can be customized by using the
link parameter, as shown on the link documentation page and in the More Powerful Data Drilling Help Center article. When the visualization from a drill is not a table, buttons allow the user to switch between the default visualization type and a data table.
For more information about visualization types, see the Visualization Types documentation page.
Experimental Labs features may or may not remain in the product, and errors may or may not be corrected. These experimental features are intended to show you functionality that could be incorporated into Looker in the future. We always welcome your feedback.
Lets users with the
create_table_calculations permission create additional, temporary fields on the Explore page that (unlike table calculations) become part of the query running in the database. Other users can see the new fields if they have the
create_table_calculations permission themselves, if they are given the Explore query’s URL, or if they are given access to a Look or dashboard that uses that field.
Use the Custom Fields Labs feature if you want to let some of your business users have these capabilities:
- Create semi-permanent measures and dimensions for a one-time or an infrequent analysis
- Create semi-permanent measures and dimensions without needing an analyst
- Visualize unmodeled data using Instant Explore from the SQL Runner
For more information, see the Adding Custom Fields documentation page.
Dashboards in Drill Menus
Automatically suggests dashboards with matching filters.
Suggested dashboards will appear in the drill menu. In systems with many dashboards, this feature decreases dashboard performance.
Dashboards display previous data while new queries are run.
If Instant Dashboards are enabled, when a dashboard loads, Looker pulls data from the cache to immediately display data from the previous run. The dashboard issues new queries that run in the background, and dashboard tiles are then updated as new data is retrieved. The spinner icon appears on the top right of each tile that is still loading, indicating that a query is running in the background and that the currently displayed data is from the last time the query was run. This has the advantage of users not seeing a blank dashboard while it’s loading, but the disadvantage of possibly showing stale data while the new queries run. Instant Dashboards are not supported by dashboards (beta).
Enabling Instant Dashboards also affects how long data is stored in the cache, since this feature relies on the existence of cached data to display.
Local Project Import
A LookML project can reference files in other locally maintained projects through the use of the
local_dependency keyword in a manifest file. Enabling this Labs feature is not required to use the
New Dashboard Experience
The New Dashboard Experience Labs feature allows users to create and view dashboards (beta), which have an updated look, customizable user-friendly filters, and a new editing flow. Turning this feature on will not impact existing dashboards. The Viewing Dashboards (Beta) documentation page provides more information.
New Groups Page
The Groups page in the Users section of the Admin menu lists and lets you manage all the user groups on your Looker instance. When New Groups Page is enabled, the Groups page displays a new, redesigned table and pagination that simplifies group management and increases performance on instances that have a large number of groups. For more information, see the New Groups Page section of the Groups documentation page.
Trend Lines in Visualizations
Enables the addition of trend lines to Cartesian charts.
This feature enhances the visualization options available for column, bar, line, area, and scatter charts using a variety of regressions.
