Openlayers Quick Query

OpenLayers Quick Query: Have you tried using geofield with openlayers_views and a map with 5000 nodes? No? I have and the result is: 280 MB, 2 min load time and all nodes are loaded into memory. But slow is not the entity_load, but the field_attach. With this short module and some custom code you can easily make your layers fast again:

Example

function hook_openlayers_quick_query_info($view) {
  if ($view->name == 'my_map') {

    // Add wkt field information
    $info['wkt_field'] = 'field_geolocation';

    // Add needed fields
    $info['fields'][] = [
      'field_name' => 'field_geolocation'
    ];
    $info['fields'][] = [
      'field_name' => 'field_other',
      'additional_fields' => TRUE,
    ];

    return $info;
  }
}

For a complete example see openlayers_quick_query.api.php.

Explanation

With this little code OL quick query takes over for this map view and the render and field_attach for the data layer view are never called. Instead all processing is done directly via the supplied information.

Assumptions

* You have a geo field called field_geolocation in your content type.

Of course for other projections and maps other parameters might be needed and this really only supports wkt fields at the moment.

You might also consider using an ajax loading for the popup bubbles instead.
