Durable execution¶
Category: Distributed systems · Status: stub
One line: Recording a long-running workflow's progress — checkpoints, an event log — so that after a crash it resumes where it stopped instead of starting over.
Also called: distributed async await, checkpointing, workflow engine, resume semantics.
