SagaRegistry

Registry for managing multiple named, reusable saga templates.

A Saga instance is safe to Saga.execute more than once (its per-run tracking state is reset at the start of every execution), so storing one by name and re-running it is the main use case for this registry -- e.g. an "order-checkout" saga built once at startup and executed per order.

Example usage:

val registry = SagaRegistry.create()

val checkout = registry.getOrCreate<OrderResult>("order-checkout") {
    step("Reserve inventory", action = { inventoryService.reserve(items) })
    step("Charge payment", action = { paymentService.charge(amount) })
}

val result = checkout.execute()
