java - Disable JPA query cache -


i have java ee program runs on wildfly 9 server. in program want record in database thousands of records in once. that's why in method use native query:

public int record(collection<myentity> entities) {      /**      * following query like:      * insert my_table (id, date, value) values      *   (1, '2016-02-24', 10),      *   (2, '2016-02-23', 8),      *   ...      *   (10000, '2016-02-01', 6);      */      stringbuilder querystring = new stringbuilder("insert my_table (id, date, value) values ");      (int = 1; <= entities.size(); i++) {         querystring.append("?,?,?)");         if (i < parameters.size()) {             querystring.append(',');         }     }      query query = getentitymanager().createnativequery(querystring.tostring());     int parameterposition = 0;     (myentity entity : entities) {         query.setparameter(++parameterposition, entity.getid());         query.setparameter(++parameterposition, entity.getdate());         query.setparameter(++parameterposition, entity.getvalue());     }      return query.executeupdate();  } 

my problem hibernate keeps in cache (i don't know how many) prepared statements. example if have 1 entity in collection, query insert my_table (id, date, value) value (?,?,?) cached, 2 entities insert my_table (id, date, value) value (?,?,?),(?,?,?) , on. said want record thousands of records, big strings cached , after while application crash ugly java heap space error.

so wonder if it's possible disable cache particular query ?
