Projection Operator

The Projection operator lets you modify a schema.

You can pass columns through to the output unaltered, you can remove columns completely, and you can create new columns using JavaScript expressions.

By default, Projection produces one row of output for every row of input. You have the option of omitting duplicate rows from the output result set.
