What problem does it solve?

Enables robust parallel spawning and result aggregation for batch, tree, or crawl-style workloads where each child is an independent durable unit and parent processes must remain crash-safe and replayable.

Core Features & Use Cases

• Parallel durable spawning: Fire N child invocations using ctx.run or ctx.rpc and collect their DurableFuture results.
• Recursive traversal: Implement depth-limited tree or web crawling that spawns children of the same durable function.
• Bounded concurrency & failure modes: Process in chunks to limit in-flight work and optionally tolerate partial failures when awaiting children.
• Use Case: Enrich a large batch of order IDs in parallel, crawl a site to fixed depth, or implement map-reduce style workers with durable retries.

Quick Start

Fan out a list of order IDs in Rust using ctx.run or ctx.rpc to spawn parallel durable children, await their results, and return the aggregated list.
