What is a Synchronous Orchestration?

A Synchronous Orchestration starts and completes without waiting for input from another process.

When should you use a Synchronous Orchestration?

For self-service applications that need Workday responses after successful data updates and for lightweight applications that can process quickly.

What can a Synchronous Orchestration receive and return?

It can receive custom requests and return custom responses, similar to a custom API.

Can a Synchronous Orchestration be invoked as an API?

Yes. You can invoke it as an API and define both the request and response.

What is the runtime duration limit for a Synchronous Orchestration for Extend apps?

5 minutes, according to the orchestration execution timeout table.

What is an Asynchronous Orchestration?

An Asynchronous Orchestration contains steps that can wait for other events to complete.

When should you use an Asynchronous Orchestration?

When the application doesn't require an immediate Workday response or needs to process a large amount of data.

What is the key difference between Synchronous and Asynchronous Orchestrations?

Synchronous orchestrations complete without waiting for other processes, while asynchronous orchestrations can wait for external or other process events.

What runtime duration does the detailed timeout table give for an Asynchronous Orchestration in an Extend app?

48 hours.

Does the provided material contain another timeout statement for orchestrations?

Introductory section states that orchestrations can run for a maximum of 20 minutes, while the detailed timeout table states 48 hours for asynchronous Extend orchestrations.

: What can trigger a Workday Business Process orchestration?

A Workday-delivered event or an Extend model business process.

When should you use a BP Triggered orchestration?

When you want to make a SOAP call for every Model BP initiation, update another system as part of a Workday Business Process, or replace a boomerang integration with an event-driven orchestration.

What is one use case for a BP Triggered orchestration?

Make a SOAP call each time the Model Business Process initiates.

What type of integration can a BP Triggered orchestration replace?

A boomerang integration, using an event-driven approach instead.

How can orchestrations be triggered or scheduled from a Workday tenant?

Through a Workday Integration System.

What is the key difference between an Orchestrate Integration and a BP Triggered orchestration?

An Orchestrate Integration is triggered/scheduled through an Integration System, while a BP Triggered orchestration is triggered by a Workday-delivered event or Extend Model BP.

Can you change an orchestration's template after creating it?

No. Once an orchestration is created with a particular template, its template cannot be changed.

Why is the orchestration template important?

It determines the type and execution model of the orchestration.

Why should orchestration steps have helpful names?

So you can easily identify where logged values came from.

How do you define input parameters that are passed from a Business Process to an orchestration?

Select Configure Request on the orchestration's Start step and add the input parameters as key/value pairs.

What is the runtime limit for a Workday Home Card orchestration?

5 minutes.

What is the runtime limit for a Synchronous Orchestration in an Extend app?

5 minutes.

What is the runtime limit for an Asynchronous Orchestration in an Extend app according to the detailed table?

48 hours.

What is the runtime limit for a Workday Integration System orchestration?

48 hours.

What is the Business Process orchestration runtime callback period?

90 days.

What does the 90-day callback period mean?

A Business Process triggered by an orchestration must complete within 90 days.

How many times can a Synchronous Orchestration recursively call itself before failing?

31 iterations

What is the maximum amount of concurrent data an orchestration can hold in memory?

200 MB.

What does the 200 MB in-memory limit include?

Data held by all in-scope values plus temporary values created while evaluating expressions

Does the 200 MB limit include orchestration heap space?

No

How can Workday handle large data items without keeping everything in memory?

Workday can manage large data items on disk using file-backed data structures.

What is the maximum concurrent data an orchestration can have on disk?

2G

What happens to data once values go out of scope?

The runtime cleans them up, and their associated disk data no longer counts toward the disk limit.

What is the maximum launch message size for an orchestration?

20 MB.

What is the maximum response message size from an HTTP API call?

500 MB.

What does the 20 MB launch message limit apply to?

The request message used to launch an orchestration.

What does the 500 MB response message limit apply to?

An individual HTTP response returned from an HTTP API call.

What is the processing time limit for a Synchronous Orchestration triggered by a presentation page?

25sec

Does the 25-second presentation-page timeout override the orchestration's configured timeout?

Yes. It takes precedence over other orchestration timeout settings.

What should you use if a presentation-page-triggered orchestration is expected to take more than 25 seconds?

Workday recommends using an Asynchronous Orchestration.

What is the maximum number of orchestrations and suborchestrations allowed in one app?

150

What is the maximum number of steps in one orchestration?

300

Synchronous vs. Asynchronous — core difference?

Synchronous waits for no other process; Asynchronous can wait for other events.

Use Synchronous for?

Quick, lightweight applications requiring an immediate Workday response.
