Incremental refresh and hybrid tables
Incremental refresh or incremental data loading is a renowned technique for controlling how the data loads into a data store, so we keep the existing data and only load the changes. Let us look at it in more detail.
From a technical standpoint in data movement, there are always two options to transfer the data from location A to location B:
