Wait / Delay Node

Pause workflow execution using fixed durations, dynamic expressions, jitter variance, and rate-limit buffers.

The Wait / Delay Node (component-wait) pauses workflow execution between steps. It is designed to handle asynchronous settlement delays, rate-limit spacing, third-party webhook arrival windows, and external system consistency buffers.

1. Operating Modes

Fixed Duration

Pauses execution for an exact configured duration:

• Supported units: Milliseconds, Seconds, Minutes, Hours.
• Example: Wait 3000 ms to allow background ledger settlement before checking transaction status.

Dynamic Duration Expression

Derives the wait duration dynamically from upstream node responses or variables:

{{ResponseBinding.InitJob.body.retryAfterSeconds}}

• Fallback Duration: Configurable fallback value if the dynamic token evaluates to null or empty.

Jitter Variance

Introduces random variance to prevent “thundering herd” problems when running parallel stress flows:

• Base Duration: 5000 ms
• Jitter Percentage: 20% (delays randomly between 4000 ms and 6000 ms).

3. Enterprise Use Cases

• Settlement & Clearing Buffers: Introducing a brief 3-second buffer after dispatching an instant payment transfer before querying ledger settlement state.
• Rate-Limit Throttling: Placing a 250ms delay inside batch loops to stay strictly within third-party API rate limits.
• Asynchronous Provisioning: Giving cloud microservices adequate spin-up time before executing downstream integration assertions.
