Reloading app data in the cloud hub

Apps in the cloud hub do not automatically update when their data sources are updated. Reloading an app updates it with the latest data from the app data sources. You can manually reload your apps or schedule reloads for your apps.

Information note You cannot reload data in the cloud hub for apps published to the cloud hub from a Qlik Sense Enterprise on Windows deployment. Apps published from Qlik Sense Enterprise on Windows can be reloaded using the QMC in Qlik Sense Enterprise on Windows.

For information about which users can reload data, see:

You can check the reload status of an app. This can be Success, Reloading, or Failed.

  • In list view of apps in the Last modified column.
  • In the app card in tile view or grouped view.
Information noteThe maximum reload time for an app is three hours. If an app takes longer than this to reload, it will fail and you will receive a message.

Scheduling reloading app data

You can create a schedule for data reloading in your app. The schedule can be based on frequency, date, and time, or when a dataset in the app is refreshed.

To set a reload schedule for an app:

  1. Click More on the app and select Reload schedule.

  2. Click Add schedule.

  3. To schedule reloads when data is refreshed, select When a dataset is refreshed in Reload the app

    To create a time-based schedule, select any of the options under Time in Reload the app.

    Information noteIf the app does not contain a dataset that is created and refreshed by Qlik Cloud Data Integration, the Time heading and the When a dataset is refreshed option are not displayed.

Time-based schedules

When you create a time-based schedule, you can pick the interval and time of the reload. You can also set a start date and an end date. If you do not set an end date, the schedule will run perpetually. Repeating reloads can be set at the following intervals:

  • Hourly

    You can set the reload to be scheduled on the hour or with a number of hours interval.

  • Daily

    You can set the reload to be scheduled daily or with a number of days interval.

  • Weekly

    You can set the reload to be scheduled weekly or with a number of weeks interval. You can also select which days of the week to schedule the reload.

  • Monthly

    You can set the reload to be scheduled monthly or with a number of months interval. You can also select which day of the month and the time of day.

Event-based schedules

You can set a schedule to reload the app when a dataset in the app is refreshed. This option is only available for apps that contain a dataset that is created and refreshed by Qlik Cloud Data Integration. For more information, see Integrating data.

Managing reload schedules

You can edit scheduled reloads for all apps that you own. Tenant admins and analytics admins can view and delete, but not edit, scheduled reload tasks.

You can remove a scheduled reload from an app by setting the schedule to Inactive and saving.

Limitations and considerations for reload schedules

  • The reload schedule is inactivated if it fails to execute five times in a row.

  • If you have a high number of queued and executing data reload processes (and additional concurrent CPU and memory intensive processes), you might notice that some reload processes execute, in some cases, noticeably after their scheduled start time. If your organization requires predictable execution of data reload schedules (start on time), consider adding dedicated capacity to your Qlik Sense SaaS subscription. For more information, see Expanded apps and dedicated capacity.

  • If you cannot see the AM option when setting the reload time for a time-based schedule, use the scroll bar.

  • The dates and times in a time-based schedule use your current time zone. Qlik Sense determines your current time zone based on your browser settings.

  • Scheduled reloads are not included for the published copy of an app. Published apps must have scheduled reloads reconfigured on the app in the managed space.

  • If you move an app with a reload schedule between spaces, the reload schedule is deleted. Recreate the schedule in the new space if required.

  • If you add or remove datasets in an app with a When a dataset is refreshed schedule, you must remove the schedule and recreate it.

  • Partial reload is not supported for When a dataset is refreshed schedules.

Partial reload

Turn on Partial reload to run a pre-defined part of the load script and update the corresponding tables. Partial reload must first be configured in the load script in the Data load editor. For information, see Partial reload.

Manually reloading app data

You can reload an app manually, adding a reload task to the reload queue.

  • Click More on the app and select Reload now.

Viewing reload history for an app

Reload history contains the reload history for the selected app. Use it to help troubleshoot scheduled reload issues. You can view the status, start and end times, and duration of past and current reloads. You can also view and download a corresponding log file.

There are two ways to view the reload history for an app.

  • In the list view of apps, click the date in the Last modified column and select View reload history.
  • Select Details of an app, and click Reload history.

Reload history of an app

Screenshot of the Reload History menu in Qlik Cloud. The Reload History menu displays the status, start time, end time, and duration of reloads in an app. The cancel button is also shown in the screenshot.

On the Reload history page, click the View button to view the reload summary. Optionally, you can also download a detailed log file. When the limit for the number of logs stored is reached, new logs will replace the oldest logs, on a first in, first out basis.

You might want to cancel a reload of your app if the reload is taking too long or the app has been updated with new data and you want to start a new reload. To cancel a reload, go to Reload history, and click Cancel.

You can see the canceled reload in your Reload history.

Viewing and deleting reload schedules

Tenant and analytics admins can view and delete reload schedules from the Management Console. This is done on the Schedules tab.

Understanding timestamps: Updated, Modified date, and Last reload date

The Updated timestamp displays towards the bottom of each app tile in the cloud hub. It same value can also be viewed by selecting More on the app, then selecting Details. The same timestamp is listed in Details as Modified date.The format of the date may differ; for example, if the app was recently updated, the Updated value on the app tile may appear like: Updated 15 minutes ago.

Last reload date is viewed by selecting More on the app, then selecting Details. This value is only refreshed when the app's data is reloaded. A reload also changes the Updated and Modified date timestamp.

Modified date and Last reload date fields in app Details

Details view displays Last reload datea and Modified date timestamps

The following table lists the operations that refresh Updated(same as Modified date) and Last reload date timestamps:
