Thanks for your detailed approach @rat , When you say with smaller chunks approach getting 10 TB of data may take in days and The approach what I am seeing currently is Table API approach(https://docs.servicenow.com/bundle/utah-api-reference/page/integrate/inbound-rest/concept/c_TableAPI...) , where in its not supporting compress techniques and limited to only 10K records does not supports referenced data, DO you any other approach where Lets say If I get incident table will i get all referenced data?
