Detect empty stream

Description

Detect Empty Stream checks whether the incoming data stream contains any rows. If the stream is empty, it outputs a single row with the same field structure but all values set to null; if the stream has data, it produces no output. Use this step when your workflow needs to take a specific action when no data is available — for example, sending a notification that a data source returned no records, or branching to an alternate path using a Filter Rows step downstream.
