What are the different types of coalesce?

hello!

I came across this question recently, can anyone clarify that are there different types of coalesce or not.

if there are then, 

what are the different types of coalesce present in SN and how do we differentiate between them.

Hi @saudfaisal 

As per Google search:

There are several types of coalesce configurations in ServiceNow, including:

• No coalesce: All imported rows are treated as new records, and no existing records are updated.
• Single-field coalesce: Updates a single record.
• Multiple-field coalesce: Coalesces on multiple fields to update an existing record.
• Conditional coalesce: Determines whether a table row should coalesce
