android - Is Parse relations/ pointers bi-directional? -


this code sets customer class, creates object in , assigns pointer connecting customer object parseuser created it.

parseuser currentuser = parseuser.getcurrentuser();   customer.put("createdby", currentuser); customer.saveinbackground;  parsequery<parseobject> query = parsequery.getquery("customer"); query.whereequalto("createdby", currentuser);  query.findinbackground(new findcallback<parseobject>()

the pointer defined customer --> user query against customers. go user need check value in createdby column reverse entire query needed. need define pointer in other direction optimize query/ speed or parse enforce bidirectionality in pointers , relations?

in mongodb afaik pointers must defined in both directions optimum query speeds. using customer class more , app should work 100k users+ same doubt applies case of parserelations. know can use 'include' key query both ways equally optimized?
