https://github.com/ray-project/langchain-ray这个仓库展示了3个ray和langchain结合的示例，包括源代码、视频讲解、博客文档，对快速认知这两个工具及如何结合使用，非常有帮助。（但不知道出于什么原因，仅不到一年，这个仓库的状态已经是Public archive了。）

让我很有印象的是RAG应用示例。

首先是特征向量化过程(Embedding/Vector Store)。Ray Data提供了并行处理数据能力，将原始PDF文件向量化后存储/索引到FAISS。这个过程如果单纯使用langchain实现，这个过程是小时级的；而引入ray data后这个过程是分钟级的。

#!/usr/bin/env bash
executingPath=$(pwd)
scriptPath=$(cd $(dirname $0);pwd)
scriptParentPath=$(cd $(dirname $0);cd ..; pwd)
scriptName=$(basename $0)

line=$(printf "%-60s")
echo "${line// /#}"
echo "Executing path : $executingPath"
