Azure Data Factory Part 5 - Types of Data Pipeline Activities
Summary
TLDRThis video from the Azure Data Factory series delves into the concept of pipelines and activities, explaining their roles in data processing. It clarifies the distinction between a pipeline, a logical grouping of activities, and an activity, a processing step within a pipeline. The video outlines three main types of activities: data movement, data transformation, and control flow, providing examples and emphasizing their importance in data factory operations. It also directs viewers to Microsoft's detailed documentation for further understanding.
