Detect empty stream
Description
Detect empty stream is a step in the Flow Plugin for Process Studio Workflows. Detect empty stream step is used to detect an empty stream. This step outputs a single row if the input stream is empty (i.e. when input stream does not contain any row); and has the same fields as the input row, but all field values are empty (null). If the input stream is not empty, the step does not give any output.
