Overview
A design pattern that composes multiple control flow primitives (conditions, loops, exit handlers) within a single pipeline to express complex execution logic.
Description
Real-world ML pipelines often require combining control flow patterns. Exit handlers wrap failure-prone sections. Parallel loops fan out over data items. Conditions within loops create nested decision trees. The composition follows nesting rules: ExitHandler at the outer level, ParallelFor for iteration, Condition for branching. Each context manager defines a scope — tasks within a scope inherit its execution constraints.
Usage
Use when a pipeline requires more than one control flow pattern — for example, parallel hyperparameter search with conditional model selection and guaranteed cleanup.
Theoretical Basis
Compositional control flow in DAG systems. Control flow contexts are composable — they can be nested to create complex execution patterns. The execution semantics are determined by the nesting order.
