…r + LLM + Vector database + Langchain integration. Since the repository is the Dozer core codebase, the appropriate solution is to create a new sample directory under the repository (e.g., `samples/llm-chatbot`) containing all necessary configuration files, SQL seeds, a Python Langchain application, and documentation. The sample will configure Dozer to source from multiple datasets (customer profiles, transactions, credit card products), expose REST/gRPC APIs, and integrate with Langchain to build a hyper-personalized credit card recommendation chatbot. The implementation includes a Docker Compose setup for easy running, a Dozer YAML config, seed SQL data, a Python script that uses Langchain to query Dozer APIs and generate personalized responses, and a README with instructions. This approach aligns with the issue's request and the repository's structure (which already contains sample configs and tests).

🎯 解决的问题
Fixes #1690
该 Issue 要求基于我们发布的 LLM Chatbot 博客文章 构建一个完整的可运行示例,演示 Dozer 如何与 LLM、向量数据库和 Langchain 集成,以实现超个性化推荐。
本文通过一个银行信用卡产品推荐的场景,展示了如何利用 Dozer 将多个数据源(客户档案、交易记录等)整合为统一的实时客户画像,并将其作为上下文传递给 LLM,从而构建一个超个性化的聊天机器人。
💡 实现方案
在仓库中新增
samples/llm-chatbot示例目录,包含以下内容:dozer-config.yamlcustomers、transactions、credit_cards)读取数据,并通过 REST/gRPC API 暴露统一的客户完整画像seed.sqllangchain_app.pydocker-compose.yamlrequirements.txtREADME.md架构概览
✅ 测试验证
手动测试步骤
启动环境
cd samples/llm-chatbot docker-compose up验证 Dozer 服务正常运行
运行 Langchain 应用
export OPENAI_API_KEY=your_api_key python langchain_app.py测试聊天机器人
预期输出
运行结果截图
在验证时,可将运行结果截图附在 PR 评论中。
📋 检查清单
