delay

Passes a message through unchanged, after waiting a configured interval.

Properties

• delay (ms) — how long to hold the message before releasing it. Must be a positive number.

Behavior

The wait blocks the message's own source, not just this one message. A timer node ticking every 200ms feeding a delay of 5000ms will not keep ticking every 200ms once a message reaches the delay — the timer's next tick can't fire until the whole chain, including the delay, finishes. This isn't unique to delay (any slow node has the same effect on its own source), but delay's entire job is waiting, so it's worth knowing up front rather than discovering it as a mysteriously slowing timer.
