Merge two streams, taking elements as they arrive from an input stream, and a trigger stream to start/stop the flow (pulling from trigger stream first, wait until true, then pulling from the input stream). (keep pulling from trigger stream, wait until false, then stop pulling from the input stream). (Repeat over)
A
TriggerMergehas oneoutport, oneinport and onetriggerinput port.Emits when the input stream has an element available, and the triggered is true Note that, trigger only impact the future input element(s), always allowing the in-flight element to go through
