30. Wrangler

    The Wrangler UI is accessible on every running CloverDX Server instance at the following URL: http://[host]:[port]/clover/wrangler. It can also be easily accessed from the Server’s login page by clicking on the Wrangler button.

    Wrangler Users

    To access and use the Wrangler UI, users must have permissions Access to the Wrangler UI and Create sandbox. It’s recommended to use the pre-configured user group called Wrangler, which already contains all the necessary permissions. See User groups for more information.

    Wrangler Workspaces

    Wrangler Workspace is a special type of sandbox used to store everything related to Wrangler. Every Wrangler user has their own Workspace automatically created when they log into the Wrangler UI for the first time.

    The name of the automatically created Workspace is wrangler_home__[username].

    The Wrangler Workspace contains the input files users uploaded into Wrangler UI; all created sources, jobs, targets and also all the output data of the executed Wrangler Jobs.

    Administrators can manage the Wrangler Workspace content in the Sandboxes section in the Server console.

    The storage for Wrangler Workspaces is by default the directory containing shared Server sandboxes, but the directory can be changed by using the workspaces.home server property. See workspaces.home for more information.

    Wrangler Jobs

    The jobs users create in CloverDX Wrangler are called Wrangler Jobs. They are saved in the Wrangler Workspace and can be executed by users.

    All executed Wrangler jobs can be viewed similarly to other Server jobs in Execution history. Every execution of a Wrangler Job is backed by a generated subgraph which implements all sources, steps and targets of the job. The jobs themselves do not have any tracking, but the underlying subgraphs track record numbers and other statistics like any other subgraphs.

    The jobs are always executed on Worker, and they are queued in the Job Queue when the load is high.


    The maximum number of Wrangler users is specified in the CloverDX Server license. The Server counts the number of used Wrangler seats as the number of currently existing Wrangler workspaces.

    To see how many Wrangler seats your license allows and how many are currently used, see license detail.

    When the number of existing workspaces exceeds the number of allowed Wrangler seats, a notification will appear in the header of the Server console. If you click on the message in the header, you will be redirected to the License section under Configuration, where you can see further information.

    If there are more used seats than the license allows, no Wrangler jobs will be executed, and users in the Wrangler UI will not be able to see data previews of their jobs. To remedy the situation, you can delete some of the existing Wrangler workspaces to decrease the number of used seats or reach out to to purchase additional Wrangler seats.
