File Upload Size Limits

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.

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.
