Postordernodes
Postordernodes are a type of computational node used in directed graphs to enforce postorder execution semantics. In this model, a node executes only after all of its input dependencies have completed processing and produced outputs. The approach mirrors the postorder principle from tree traversal, where child tasks are resolved before their parent task.
Operationally, a postordernode registers its prerequisites and awaits completion signals from its predecessors. When all inputs
Key characteristics include a reliance on a directed acyclic graph, explicit dependency tracking, and barrier-like synchronization
Common use cases encompass parallel evaluation of expression trees, incremental data processing pipelines, and build or
Practical considerations include handling cycles or deadlocks, fault tolerance and recovery, and ensuring idempotent operations to
