Conditional Logic Execution

via “conditional step execution based on expressions and previous step outputs”

Kubernetes-native workflow engine.

Unique: Implements a lightweight expression evaluator in the workflow-controller (not in pods) that references step outputs and parameters, enabling decisions to be made before pod creation rather than within container logic. Expressions are evaluated synchronously during reconciliation loops.

vs others: More declarative than Airflow's branching (no custom Python operators needed) and simpler than Prefect's conditional tasks (no task-level state management), but less expressive than general-purpose programming languages.
