elvis@omarsar0 · X智能体RAG流程的瓶颈通常不在大语言模型调用，而在于底层数据平面的序列化与分布式协调开销。新研究提出的AAFLOW是一个统一分布式运行时，将智能体工作流建模为基于Apache Arrow和Cylon的算子抽象，通过零拷贝数据平面直接连接预处理、嵌入和检索环节，并采用资源确定性调度与异步批处理降低协调成本。该方案实现了高达4.64倍的流水线加速，嵌入与更新阶段性能提升2.8倍，且所有收益均源于数据流优化，并未涉及大语言模型推理加速。
// Scalable Patterns for Agentic AI Workflows //
Besides context engineering， we should be putting a lot more system engineering efforts around agents.
This paper shows an example of why it matters.

Let's start with an important question： Where does your agentic RAG pipeline actually lose time？
It's almost never the LLM call. It's usually the data plane underneath. Serialization between preprocessing， embedding， and vector retrieval， plus coordination overhead between distributed services.
New work introduces AAFLOW， a unified distributed runtime that models agentic workflows as an operator abstraction over Apache Arrow and Cylon. A zero-copy data plane connects preprocessing， embedding， and retrieval directly. Resource-deterministic scheduling and async batching cut coordination cost.
