How Scriptrunner Listener works internally with Events

[Sam007]

I am working on a project where I create a Jira ticket and it will also update one of my legacy system with same information using a rest call.

I have setup issue created event in Scriptrunner Listener. whenever an issue is created in JIRA it creates a POST call to the legacy system. In scriptrunner listener I have an asynchronous piece of code which initiate a post call so Jira doesn't have to wait for the response from the legacy system.

I want to know more details how scriptrunner listerner handles events internally, let's say if I create 1000 Jira tickets exactly at the same time, does Scriptrunner initiates 1000 create events for them at the same time?
