If the source is RDMS, then you can write analytic function in the select statement to assign count to each row. And use this count column to route the records to respective target.

If the source is a flat (this is generally asked in interviews), then you can use aggregator to assign count to each row after grouping based on the key and use joiner to join back to source records that way all the rows coming from the SQ will have respective counts. Use router to route them to respective targets.
