Loop Iteration Over Collections

via “iterative execution over collections with foreach”

A durable workflow execution engine for Elixir

Unique: Implements iteration as a workflow primitive with automatic persistence of iteration state, enabling resumable batch processing without custom loop logic. Each iteration is a separate step execution with independent retry and error handling, providing fine-grained observability into batch processing.

vs others: More declarative than manual loop logic in step functions and simpler than Temporal's activity loops (which require custom activity implementations). Iteration state is fully queryable and resumable.
