Azure Data Factory - Incrementally load data from Azure SQL to Azure Data Lake using Watermark

Azure Data Factory - Incrementally load data from Azure SQL to Azure Data Lake using Watermark
In a data integration solution, incrementally (or delta) loading data after an initial full data load is a widely used scenario. The tutorials in this section show you different ways of loading data incrementally by using Azure Data Factory.

In this case, you define a watermark in your source database. A watermark is a column that has the last updated time stamp or an incrementing key. The delta loading solution loads the changed data between an old watermark and a new watermark.

In this Demo we will do following
