Yi discusses the advantages of using Kafka queues for communication between pipeline stages, highlighting improved failure isolation and guaranteed event order. He contrasts this with the limitations of RPC, noting the trade-offs in latency and precision. Additionally, he compares state store options in Flink and Spark, emphasizing that Flink offers a robust free solution with RocksDB, while Spark requires a paid option for larger states, impacting cost and performance.
