Aggregate based on Col1 and count.

If you have more than one column and you want other columns to be intact, you need to split it using a copy stage aggregate it on COL1 and then join it back with the original stream on COL1

If your source is a database you can select that column and a count(*) next to it, with the first column in the group by clause.

use the aggregator stage with columns COL1 and count(COL1).
