 Dagster Pipes is a toolkit for building integrations between Dagster and external execution environments. It standardizes the process of passing parameters, injecting context information, ingesting logs, and collecting metadata all while remaining agnostic to how remote computations are launched in those environments. This enables the separation of orchestration and business logic in the Dagster ecosystem.
