Introduction to DataFlow

Share this page

This section covers high-level concepts about dataflows and the Actian DataFlow architecture. It is a good place to start learning about the building blocks of DataFlow before creating applications or custom operators.

• For an understanding of the basic computing issues DataFlow is intended to address, see Overview.

• To learn about how applications are described and executed in DataFlow, refer to Application Model and Execution Modes. Functions discusses a refinement to these models, and Expression Language presents an alternative way to compose functions.

• To learn about how DataFlow represents data, see Tokens and Types.

• To learn about how DataFlow conceptually works with files, refer to Input/Output and Formats and Schemas.

• To learn about how YARN on a Hadoop cluster works with DataFlow Cluster Manager, see YARN on Hadoop Cluster.

• To learn about supported file systems, formats, and text types, see Supported Files and Formats and Supported Text Types.
