gigaspace context in initial load

hi , is it possible to inject gigaspace context during initial load, basically, i have a customer table, which has a column partition id, and customer data gets bootstrapped into each partition however i am not willing to add partition id to other tables like agreement and description tables, also our domain model is such that agreement and description tables cannot be considered as a child to customer table they are separate business entities. for performance reasons i want to collocate all of customers data in same partition. so idea was to load databsequentially one data iterator after another n in agreement data iterator i first fetch the customers and for all those customers i query the db
