+## Related Issue
+Closes #22557
+
+## Summary
+This PR adds Clickzetta Lakehouse as a vector database option in Dify, enabling customers to use Clickzetta as their unified data platform for both vector and structured data storage.
+
+## Key Features
+- ✅ Full BaseVector interface implementation
+- ✅ HNSW vector indexing with automatic management
+- ✅ Concurrent write operations with queue mechanism
+- ✅ Chinese text analysis and full-text search
+- ✅ Comprehensive error handling and retry mechanisms
+
+## Testing Status
+- 🧪 **Standalone Tests**: 3/3 passed (100%)
+- 🧪 **Integration Tests**: 8/8 passed (100%)
+- 🧪 **Performance**: Vector search ~170ms, Insert rate ~5.3 docs/sec
+- 🧪 **Real Environment**: Validated with actual Clickzetta Lakehouse instance
+
+## Business Impact
+Real commercial customers are actively waiting for this Dify + Clickzetta integration solution for trial validation. This integration eliminates the need for separate vector database infrastructure while maintaining enterprise-grade performance and reliability.

+
+## 第2步：回复维护者
+
+在PR #22551 中回复 @crazywoola：
+
+```markdown
+@crazywoola Thank you for the feedback! I've created issue #22557 to document this feature request as requested.
+
+The issue provides comprehensive context including:
+- **Business justification** based on direct customer demand
+- **Technical specifications** and implementation details
+- **Testing evidence** with 100% pass rate across all test suites
+- **Performance benchmarks** validated in real Clickzetta environments
+
+## Key Testing Results:
+- 🧪 Standalone Tests: 3/3 passed (100%)
+- 🧪 Integration Tests: 8/8 passed (100%)
+- 🧪 Performance: Vector search ~170ms, Insert rate ~5.3 docs/sec
+- 🧪 Real Environment: Validated with actual Clickzetta Lakehouse instance
+
+The implementation is complete, thoroughly tested, and ready for integration. It follows Dify's existing vector database patterns and maintains full backward compatibility.
+
+Please let me know if you need any additional information or modifications to move this forward.
+```
+
+## 第3步：准备后续跟进
+
+如果维护者需要更多信息，准备以下资源：
+
+### 可能的问题和回答：
+
+**Q: 为什么选择Clickzetta？**
+A: 客户已经在使用Clickzetta作为统一数据平台，希望避免部署和维护额外的向量数据库基础设施。
+
+**Q: 性能如何？**
+A: 测试显示向量搜索平均170ms，插入速度5.3 docs/sec，支持HNSW索引优化。
+
+**Q: 维护成本？**
+A: 实现遵循Dify现有模式，维护成本最小化。包含完整的错误处理和重试机制。
+
+**Q: 向后兼容性？**
+A: 完全向后兼容，不影响现有配置。只有在显式配置VECTOR_STORE=clickzetta时才激活。
+
+## 第4步：监控反馈
+
+定期检查以下内容：
+- PR评论和反馈
+- Issue讨论和标签变化
+- 是否有其他维护者参与讨论
+
+## 第5步：准备演示（如果需要）
+
+如果维护者需要演示，准备以下材料：
+- 配置演示视频
+- 性能测试结果展示
+- 与现有向量数据库的对比
+
+---
+
+**时间线预期：**
+- 立即：更新PR描述和回复维护者
+- 1-3天：等待维护者初步反馈
+- 1周内：完成技术讨论和可能的修改
+- 2周内：目标合并或明确后续步骤
