Drupal 8 commerce (2.x) - multi currency how to

For multi-currency in drupal 7 commerce we had it all running out of the box with drupal multicurrency modul. You had price fields per currency and rules that would solve that. There is no out of the box solution like that yet, but this module is pretty close to it.

Clear cache of particular entity

For debugging purposes I need to clear cache for particular drupal commerce order, but this can be done for any entity, just replace table name and id's in code below

 $table = 'cache_entity_commerce_order';
 $id ="776764";
 cache_clear_all($id, $table);
