Filter node

You can rename or exclude fields at any point in a stream. For example, as a medical researcher, you may not be concerned about the potassium level (field-level data) of patients (record-level data); therefore, you can filter out the K (potassium) field. This can be done using a separate Filter node or using the Filter tab on a source or output node. The functionality is the same regardless of which node it is accessed from.

  • From import nodes, you can rename or filter fields as the data is read into Watson Studio.
  • Using a Filter node, you can rename or filter fields at any point in the stream.
  • You can use the Filter tab in any of the above nodes to define or edit multiple response sets.
  • Finally, you can use a Filter node to map fields from one source node to another.
