Dataflow Architecture

Kind: style

Layer: Execution Core

Record: architecture:dataflow-architecture

Severity: contextual

Scope: processing, workflow, stream

Canonical: Ontology

A convention of arranging processing as a graph of stages connected by explicit data edges, where a stage runs when its inputs arrive.

Listed in Architecture principles, after Forward-Only Processing and before Stateless Processing.
