Merge Typed Streams into One Pipeline

Combines multiple streams of the same message type.

When to use

Use Merge to converge equivalent branches without business logic.

  • Forwards values as they arrive from any source.
  • Does not generate a function or alter the value type.

PropertyTypeDescription
sourcesStream[]

Additional upstream streams. Source count and type constraints depend on the operator.

xPosnumber

Horizontal designer coordinate. It has no runtime effect; missing positions can be supplied by layout.

yPosnumber

Vertical designer coordinate. It has no runtime effect; missing positions can be supplied by layout.
