Use sorted input.
The aggregator stores data in the aggregate cache until it
completes aggregate calculations. When u run a session that
uses an aggregator transformation, the informatica server
creates index and data caches in memory to process the
transformation. If the informatica server requires more
space, it stores overflow values in cache files.
