SAS Visual Investigator Scenario flow -Deduplicating Events

[krishnaavm123]

Hi 

I'm experiencing an issue with the scenario flow trigger and the refresh alerts job (initiated via an API call) taking longer than expected. Upon reviewing the GUI, I've noticed that one specific task(highlighted in below attached image) is consuming significantly more time than others.

I would appreciate any insights into what this task does, particularly how it handles the comparison of duplicate events. Additionally, I would be grateful for any suggestions on how to optimize and improve the performance of this job.
