Managing changes only data from REST endpoints in VBCS application?

Content

Hi All,

Are there any ways to handle changes only records in VBCS applications.

Let's say, 

First time loading the application, need to fetch all the pending workers from HCM cloud through rest apis, how are we going to push these data into BOs from Service Connection's response? Please share any blogs which talks about this.

From second time loading the application, will call the atom feeds on the pending workers rest apis and get only the changed records - this time how can we manage the insertion/deletion of the records into the same BOs.
