File Upload Size Limits

Squirro enforces a default 96 MB file upload limit via two settings that must be kept in sync:

1. frontend.max-file-size

   Server configuration

2. client_max_body_size

   Nginx proxy configuration

Modifying Upload Limits

To increase the file upload limit:

1. Update the frontend configuration

   Set frontend.max-file-size (in bytes) in the server configuration. This setting is managed through Squirro’s Configuration Service under the Server space.

2. Update the nginx configuration

   Edit the nginx configuration file /etc/nginx/nginx.conf to set client_max_body_size and restart the nginx service.

   sudo nano /etc/nginx/nginx.conf
   

   sudo systemctl restart nginx
   

An important rule to follow is to ensure that the frontend.max-file-size value is set to be less than or equal to the client_max_body_size value.

Note

Custom asset uploads, such as ui_bundle deployments made with squirro_asset or neo-ui deploy, use a separate limit of 512 MB. That limit is set on the /api/topic/v0/<tenant>/assets/ location in /etc/nginx/conf.d/topic.conf and is not affected by the client_max_body_size value in /etc/nginx/nginx.conf. To change it, edit topic.conf and restart nginx.

Example Configuration

To set a 200 MB upload limit, adjust the settings as follows:

1. Frontend Configuration (via Configuration Service)

   frontend.max-file-size = 209715200
   

2. Nginx Configuration

   client_max_body_size 200m;
   

Additional Considerations

• Datasource plugins

  They may have additional limits.

• Large file timeouts

  Consider adjusting client_body_timeout in nginx for slow connections.

• PDF conversion timeouts

  May need proxy_read_timeout adjustments for large PDF files.
