Loading files larger than 50MB from web storage connectors such Dropbox, Office 365SharePoint, SFTP, Amazon S3 and similar leads to: 

Data file size exceeded file streaming buffer size. Adjust the StreamingBufferSizeMB setting.

Environment

Qlik Sense Enterprise on Windows 
Qlik Cloud 

Resolution

Qlik Sense Enterprise on Windows (client-managed):

The solution requires us to modify the Qlik Sense Engine settings.ini. See How to modify Qlik Sense Engine settings.ini for details on the procedure.

1. Stop the Engine Server
2. Go to C:\ProgramData\Qlik\Sense\Engine
3. Create a backup of the Settings.ini 
4. Open the Settings.ini file
5. Add StreamingBufferSizeMB=1024 line  (higher values are not currently supported by connectors)
6. Add an empty line after the above parameter if the parameter is the last one to be added
7. Save
8. Restart the Engine Service

Qlik Cloud

The value cannot be configured in Qlik Cloud. A workaround is to split the big data files by e.g. months.

Hello @damianbadura1 higher values than 1024 are not currently supported by our connectors.

I recommend logging into our Ideation Platform and voting and commenting on 432087: Allow to increase the StreamingBufferSize on QlikSense Enterprise.

All the best,
Sonja
