Inside iQIYI's Agent Team: Automating Cross-Service Big Data Diagnosis

iQIYI built a Big Data Assistant using an Agent Team architecture where a Coordinator delegates tasks to domain-specific Service Agents (Scheduling, Spark, Flink, ML, Data Lake, StarRocks) that collaborate via a shared blackboard to diagnose cross-service issues, evolving from rule-based workflows to LangGraph-based agents with Harness engineering for context management, tool control, and observability.
