Snowflake target endpoints filling disk space with CSV files

[raffaelec]

Hello everyone,

I have configured several replication tasks that read from Log Streams and replicate data to Snowflake targets.

Today, all replication tasks stopped because the disk space on the server became almost full. As a result, it wasn’t even possible to resume or reload the tasks.

After checking the disk, I noticed that all replication tasks targeting Snowflake were retaining CSV files (zipped as GZ files) related to applied changes in the cloud/bulk folder.

This behaviour is unexpected and was not observed prior to the recent Qlik Replicate upgrade. The current versions are:

• Qlik Replicate: November 2025
• Snowflake ODBC driver: 3.04.01.00

I reviewed the Snowflake endpoint configuration and didn’t find any setting that would indicate that CSV files should be retained locally. I’m aware of the internal parameter "keepCSVFiles", which causes Qlik Replicate to keep CSV files on disk. However, this parameter is not enabled on the Snowflake endpoints. When selected in the internal parameters list, it clearly shows as disabled, which I understand to be the default behaviour.

Could you please advise how to prevent Qlik Replicate from retaining these CSV files and avoid disk space saturation? Moreover, could this behaviour be related to the upgrade to Qlik Replicate November 2025?

Thank you in advance for your support.

Best regards

Hello @raffaelec ,

Thanks for the post.

Could you please help by sharing the following details?

1. The Replicate version number (for example, eg 2025.11.0.164)

2. The CSV file path and file name(s)

3. Please check the task log file(s) to see if any exceptions/warnings/errors before the CSV files accumulation

We’ll review the information and get back to you.

Please note that we may need you to open a support ticket and provide Trace-level task log files, as task logs cannot be uploaded here due to this being a public forum.

Regards,

John.

Hi @raffaelec ,

On the Snowflake endpoint's advanced setting, could you check whether keepCSVFiles is enabled?

Hi @raffaelec 

Please ensure also that keepErrorFiles is not enabled on the target endpoints, Advanced tab, Internal parameters. Since this and keepCSVFfiles are "off" by default, you should not see them in the list at all. When the checkboxes are not active, when you click OK you should be prompted that there are parameters that have default values that have not changed, asking if you want to change them. You should respond "no" which will actually remove these parameters from the list.

Thanks,

Dana

Hello everyone,

Thank you for your support.

Below are the requested details:

• The Qlik Replicate version in use is: November 2025 (2025.11.0.164).
• The CSV files are stored in the following directory:
  C:\qlikreplicate\tasks\task_name\cloud\bulk.
• The same issue is also occurring on another machine, where the files are stored under:
  E:\Qlik Replicate\data\tasks\task_name\cloud\bulk.
• There are no errors or warnings in the log files indicating that the CSV files are being retained on the local machine.
• When I search for keepErrorFiles and keepCSVFiles under the Internal Parameters tab, both parameters are unchecked. When left unchecked, the UI prompts that they should be removed from the list unless their default values are being changed.
• I also increased the log verbosity to the highest level for the following parameters: SERVER, SOURCE_UNLOAD, SOURCE_CAPTURE, SORTER_STORAGE, TARGET_LOAD, TARGET_APPLY, TASK_MANAGER, TABLES_MANAGER, METADATA_MANAGER.
  In the logs, CSV files are referenced only for the following operations:
  • compression to GZIP;
  • upload to the Snowflake internal stage via PUT;
  • successful upload confirmation.
• There is no reference to the removal or cleanup of the CSV files.

Please let me know if you need any additional information or tests from my side.

Thank you again for your help.

Best regards

Hi @raffaelec ,

I am able to reproduce the issue. The CSV files are only overwritten when the task is restarted. Please open a support ticket.
