This aggregate cache is the place where the aggregate stores the data until the completion of the aggregate calculations. In the case of a session which performs a aggregator transformation, the server being used by the Informatica will be creating an index & it is here where the data catches the memory in to commence with the PROCESS of the ongoing transformation. And also, in the cases where the server REQUIRES additional space, the cache FILES will be handy to store these OVERFLOW VALUES.
