What is role of ‘type’ => ‘static’ in Magento 2 data patch?

Recently I saw Setup/Patch/Data with 'type' => 'static'

$eavSetup->addAttribute(
        MagentoCatalogModelProduct::ENTITY,
        'attribute_code',
        [
            'group' => 'General',
            'label' => 'Product Type ID',
            'type'  => 'static',
            'input' => 'select',
            'source' => VendorModuleModelSourceSource::class,
            'required' => false,
            'sort_order' => 1,
            'global' => Attribute::SCOPE_GLOBAL,
            'used_in_product_listing' => false,
            'visible_on_front' => false,
        ]
    );

How does this static type work and when should I use it?
Thank’s for any information))
