Azure Data Engineering Interview Questions Part4

1.What are mapping data flows?

Azure Data Factory has comprehensive data transformation and integration capabilities. For those looking for a simpler data integration experience compared to Data Factory Pipelines, Microsoft provides Mapping Data Flows which do not require writing any code.

Mapping Data Flows in Azure Data Factory are a visual way to design data transformation flows. The data flows created using Mapping Data Flows, internally become Azure Data Factory activities and get executed as a part of the Azure Data Factory Pipelines. The Data Flows are compatible with Azure Data Factory’s scheduling, control, flow, and monitoring features.

Mapping Data Flows can be created within the same Azure Data Factory resources pane as Pipelines.

Apart from the graphical user interface for creating Data Flows, there is a configuration panel at the bottom of the screen. Optimization Settings are available on the configuration panel with the options represented using pictures:
