Under Vercel's stateless function model, time-consuming tasks should return a response as quickly as possible and then be moved to a queue or background task, and temporary state should be stored in external storage rather than process memory.

VerifiedTemporal addresses fault tolerance for long-running tasks by persisting execution state, enabling recovery from the point of interruption even if the process crashes.73% similarUnverifiedUnlike stateless "function-as-a-service" approaches, the always-on model requires maintaining contextual state across multiple event cycles, placing higher engineering demands on memory management and state persistence.72% similarUnverifiedThe core idea of persistent task frameworks (such as Temporal, Restate, Pi Durable) is to write the execution state of each step of a task to persistent storage, so that the task can resume from the breakpoint after a failure and the same task will not be triggered repeatedly.71% similarUnverifiedThe ledger mechanism is essentially a persistent task queue in engineering terms, decoupling task state from volatile session context by writing it to external storage, allowing agent work to be resumed after a session interruption.71% similar
