A document summarization pipeline processes 50,000 documents per day. — Agentic Systems Engineer Practice — Claude Cert Academy

A document summarization pipeline processes 50,000 documents per day. Each summary is independent of the others. Which architecture is most appropriate?

• Hub-and-spoke with a central coordinator that routes each document
• A leaderless swarm where workers pull from a shared queue
• A critic-generator loop where each document is reviewed before summarizing
• A sequential chain where each document passes through five specialist agents

Answer: A leaderless swarm where workers pull from a shared queue

Document summarization is embarrassingly parallel: each document is independent, the task is homogeneous, and no inter-document coordination is needed. A leaderless swarm (or thin-orchestrator swarm) where workers pull from a shared queue delivers near-linear throughput scaling. Hub-and-spoke adds unnecessary coordination overhead. Critic-generator loops and sequential chains both increase latency without benefit for this task class.
