Slice nodes help you retain fields that you require in subsequent nodes. You can use
the multiple slice nodes to create subsets of fields from one source node. Each slice node lets
you remove fields from any previously created nodes.

After you select a source node, select the fields that you want to keep. The fields that you
don't select are dropped from the dataset created by the slice node and the dropped fields
aren't available to use in nodes that use the slice node as source.
