Calling Other Processes

Learn how one process can call another process in Kognitos.

Overview

In Kognitos, one process can call and run another process. The called process is referred to as a subprocess. There are many advantages of using subprocesses:

• Modularity: Decomposing automations into smaller processes enhances structure and organization.

• Readability: Well-organized automations are easier to read and understand.

• Scalability: Automations can be scaled to handle multiple tasks.

• Maintainability: Isolated processes simplify debugging and updating individual components.

Mechanisms

There are several ways to call another process in Kognitos:

1. Calling a Process: This method is ideal for single-run scenarios where you need to capture the result and status of a subprocess.

2. Invoke: This method is useful for scenarios where the parent process can continue executing without waiting for the subprocess's status or completion.

3. Starting Parallel Runs: This method provides control over parallel execution when handling multiple subprocesses simultaneously.

Comparison

Aspect	Calling a Subprocess	Invoking a Subprocess	Starting Parallel Runs
Syntax	run <procedure name>	invoke <procedure name>	start a run where the procedure is <procedure name>
Execution Style	Sequential Processing	Sequential Processing	Parallel Processing
Performance	Slower overall (each subprocess runs separately)	Slower overall (each subprocess runs separately)	Faster for many items (since runs happen in parallel)
General Usage	When tasks or items are independent and you want the result / status of a run	When tasks or items are independent and you don't need the result / status or a run	When tasks or items are dependent or rely on one another
Document Processing	Use when each document is independent and can be processed in isolation	Use when each document is independent and can be processed in isolation	Use when documents are dependent on one another, or the final outputs need to be aggregated
Example	run "to process the sales order" the attachment	invoke "to process the sales order" with the file is the document	get the attachments process each attachment as follows start a run where the procedure is "to process the sales order" the attachment wait for the runs get the runs's results as the sales orders
