In this video we will cover how to perform Incremental data load with Python ETL pipeline. The incremental data load approach in ETL (Extract, Transform and Load) is the ideal design pattern. In this process, we identify and process new and modified rows since the last ETL run. Incremental data load is efficient in the sense that we only process a subset of rows and it utilizes less resources.
We will focus on Source Change Detection technique today.
