Union Streams Step

Merges input formats of two defined inputs into a single output format (horizontal merge). Data is read from the individual inputs (in_a or in_b) and written to the output.

This step is available for standalone plans, embedded plans, and transformation catalog items.

Therefore, in the output there are merged-format data records, where each row contains data read from either in_a or in_b input.

Configuration

  1. From other steps, create a connection to in_a and in_b, as required.

  2. Select Add Union mapping and specify:

    1. Destination: Destination column name.

    2. In a: Data to be input from in_a.

    3. In b: Data to be input from in_b.

  3. Repeat as necessary.
