Throttle

Purpose​

Throttle Asset (Throttle Flow Asset)

The Throttle Asset allows you to slow down processing speed within the leg of a Workflow where this Processor is inserted.

Typical use cases are when you do not want to overburden an external system with too many requests in too little time. Using the Throttle Asset you can control throughput based on only a few parameters.

Prerequisites​

None.

Configuration​

Name & Description​

Name & Description (Throttle Flow Asset)

  • Name : Name of the Asset. Spaces are not allowed in the name.

  • Description : Enter a description.

The Asset Usage box shows how many times this Asset is used and which parts are referencing it. Click to expand and then click to follow, if any.

Asset Dependencies​

Use this section to add Formats which you plan to use as part of your filtering and routing rules.

Why do I have to add formats here?
Doesn't the system know which Formats I am using? layline.io automatically understands when you are using Formats as part of your input and output processors and automatically mounts them at runtime. But when you are referencing Formats which are not used as part of an input or output Processor directly, but rather referenced in a Javascript Flow Processor or Quickscript, then the system may not be aware that you are using this format within any of those scripts. This would result in a runtime error.

To avoid this, you can explicitly mention the Formats you are referencing in your scripts. This ensures, that these Formats will always be mounted at runtime. So it is best practice to add Formats which are referenced in this Asset here.

Asset Dependency

To add formats click on Add Dependency and select the Format you wish to add as a dependency. Repeat for any other Format dependency.

Input Ports​

Input Ports

This Processor can only have one Input Port from which it receives data to process.

A port can have a name and description. A Name is mandatory.

You cannot delete the only Input Port.

Output Ports​

This Processor can only have one Output Port to send messages on within the Workflow.

Output Ports

A port can have a name and description. A Port Name is mandatory.

You cannot delete the only Output Port.

Throttle Settings​

This is where you define how to actually throttle the flow. The paradigm is that you define how many messages per time interval should be allowed to pass.

Throttle Settings (Throttle Flow Asset)

What does this setting define?: "Throttle the processing flow to 500 messages for every one second."

  • Messages per Period: The number of messages which are allowed to pass per time period (interval).

  • Temporal amount of Period: This value is best described in the connection with the next parameter Temporal unit of Period. Let's assume the unit is Second, and the amount which we enter field is 2. This defines, that message throughput should be limited by e.g. 500 (defined in Messages per Period) message for each two second interval.

  • Temporal unit of Period: The interval unit, e.g. Seconds, Minutes, etc..
