Adding your configuration through env vars

Filters

Change Invalidation interval

Default interval is 1 minutes.

add_filter('c3_invalidation_interval', function( $interval_minutes ) {
    $custom_interval = 1;
    return $custom_interval;
} );

Change Invalidation retry interval

Default interval is 1 minutes.

add_filter('c3_invalidation_cron_interval', function( $interval_minutes ) {
    $custom_interval = 1;
    return $custom_interval;
} );

Change Invalidation items limit

Default limit is 100.

add_filter( 'c3_invalidation_item_limits', function( $limits ) {
    $custom_limit = 300;
    return $custom_limit;
} );

Customize/Overwrite the invalidation path

Using the c3_invalidation_items filter, we can update the invalidation path.

add_filter( 'c3_invalidation_items', function($items){  
        return array('/*'); 
});

add_filter( 'c3_invalidation_items', function( $items, $post ) {
    if ( 'should-overwritten' === $post->post_name) {
        return ['/slug-overwritten'];
    }
    return $items;
}, 10, 2 );

Change or Stop loading bundled AWS SDK (Since v6.0.0)

Use c3_aws_sdk_path filter, to relace the AWS SDK library path.

add_filter( 'c3_aws_sdk_path', function () {
	return 'YOUR/CUSTOM/AWS/SDK/ENTRY/POINT.php';
} );

If return null, the plugin will not load bundled AWS SDK.

add_filter( 'c3_aws_sdk_path', function () {
	return null;
} );
