what is incremental load and how it works?

Question

Accepted Answer

Incremental load is a process of updating a data warehouse or database by adding only the new or modified data.

Incremental load is used to minimize the amount of data that needs to be processed and loaded.
It involves identifying the changes in the source data and applying those changes to the target system.
Common techniques for incremental load include using timestamps, change data capture, or comparing checksums.
For example, in an e-commerce website, only the new orders since the last load would be added to the database.
Incremental load improves efficiency, reduces processing time, and ensures data consistency.
