Qlik Analytics: Data file size exceeded file streaming buffer size. Adjust the StreamingBufferSizeMB setting.

Sonja_Bauernfeind — Tue, 17 Feb 2026 11:08:05 GMT

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

Resolution

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.

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

Hello @abTech

The Desktop Client also has a settings.ini, it is stored in C:\Users\USERNAME\Documents\Qlik\Sense.

Here's an article which documents the change of a specific setting; you can use that as a template: How to enable Qlik Sense Desktop debug level logging

All the best,

By the way is there any technical details about this setting (StreamingBufferSizeMB)?
I mean how does it influence on performance etc.
For example I have 24 running tasks at the same time, all of them are reading files. If I set StreamingBufferSizeMB to 1024 does it mean that the Qlik will reserve more memory like 24*(1024-<DefaultStreamingBufferSizeMB>)Mb?
And what is the default StreamingBufferSizeMB?
Or I can set 1024 and the memory consumption will be the same as I have set it to 256?

Its amazing to be able to stream from your google bucket into Qlik. Any approx date on when the max StreamingBufferSize will be increased to > 1024mb?

thanks in advance

Paul

What is a biggest available value for StreamingBufferSizeMB? 1024? Is it for each file that is retrieved from Dropbox, Office 365SharePoint, SFTP, Amazon S3 or sum for all running at the same time?

Sonja_Bauernfeind — Tue, 21 Jan 2025 09:46:27 GMT

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
