What exactly is a DB Drain in ServiceNow platform?

ServiceNow Inc. has created various DB Drain change records for our instances in the past few months; however those are not accompanied by the usual KB Article with additional information; so I will like to know:
1. What exactly is DB Drain in ServiceNow platform?

2. What are the steps for ServiceNow DB Drain?

3. What is the end goal of the DB Drain?

And in case you don't have access to the article:

And ofcourse you can always create a ServiceNow Support Case to get this further clarified.

Hi @KarenFinlay 

Its kind of data management process for large tables, identify and remove unnecessary or outdated data from the database in order to reduce its size and improve performance

Refer the below KB as shared by @Mark Roethof
