+
+If I had not sprained my ankle on Labor Day in 2021, I might not have walked the path
+from lakehouse cloud-native to vector multimodal AI native.
+Yes, 2025 marks my fifth year of grinding in the database industry.
+It is year-end reflection time again.
+I recently did a hard retcon of my own history, but the ritual still matters.
+This time I want to talk more about myself.
+
+## Just Talking About Work
+
+I still work at a database company.
+Yes, "still" means I switched again.
+At the end of December, I joined OceanBase to work on open-source projects around
+databases and the AI ecosystem.
+This is the third database company in my career.
+
+For most of 2025 I worked on GraphRAG at NebulaGraph.
+Even though the track is crowded and no longer hot, my team and I still delivered a solid answer
+over the past year — 95% accuracy in domain-specific evaluations, and overall cost reduced to a
+level comparable to vector plus full-text hybrid indexes.
+It almost paved the road for wider adoption of graph-based document RAG.
+
+Work-driven outputs also created some positive impact.
+In March, when I researched MCP integration, I designed and implemented the first MCP
+integration in the LlamaIndex ecosystem, and contributed it upstream as llama-index-tools-mcp.
+After the community refined it further, it became a top 2% download package in the Python ecosystem.
+
+I am not a workaholic or a researcher.
+If we talk about code taste, among the colleagues I have worked with, I am probably just average.
+Even so, I can still shine.
+In the NebulaGraph community awards at the end of 2025, I was recognized by my peers.
+Thanks to everyone for the support and help.
+Though our paths are far apart, we will meet again.
+
+## May Open Source Bless Us
+
+Because the GenAI platform I work on is a commercial product, my open-source participation
+has changed.
+More often now, I do things from the angle of requirement research and delivery.
+The llama-index-tools-mcp mentioned above is one such result.
+
+I also explored coding agents.
+Following ampcode's article, I made a simple Python implementation.
+Later explorations became the foundation of my PyCon China 2025 talk,
+"Building a Multi-Agent Collaborative CLI Coding Assistant from Scratch."
+
+As a snippet from that talk, I introduced a Python SDK I wrote for the agent client protocol.
+I never expected that a few months later it would be integrated by kimi-cli, openhands, and others,
+and eventually become part of the official SDK.
+Monthly downloads passed one million, and I gained a new role as a maintainer.
+
+I also put work into Apache projects.
+I split several OpenDAL subprojects out of the repo, and recently spent some late nights
+on the Rust implementation of DataSketches.
+
+Open source might not be better or worse with me in it, but I do draw nourishment and momentum
+from it.
+The good things I once had seem to have come alongside open source.
+Even so, I still have too many promises left behind and failed to deliver.
+
+## Toward a Better Life
+
+The most important change this year is that, because I moved to Hangzhou for work at the end
+of the year, I finally ended a four-year long-distance relationship, now in its eighth year.
+I also unlocked more memories with my girlfriend, like practicing "goldfish mouth" at G.E.M.'s
+concert, and getting fan-made materials from wmls at a Mayday concert.
+
+I tried to pick up new skills through learning.
+I can still only play "Lan Hua Cao" by following the sheet, but at least I can recognize
+my guitar chords again.
+I practiced house dance for a while.
+Keeping up with other people's rhythm is already a big challenge for me, but moving with the beat
+always helps me relax.
+
+I have two not-so-cute cats.
+For a while they would scratch the door open at midnight and jump onto me to rave.
+Honestly, I have not taken good enough care of them.
+But Goji still shows me his little belly, and Aloe has been willing to come over for a tiny bite
+of cat treat after we moved to Hangzhou.
+
+Life, oh life.
+Days and nights, but when I pick up the pen I do not know what to write.
+Things are okay, no big storms.
+In a recent checkup, I did not see fatty liver on the report anymore.
+
+## A Few Lines for AI
+
+Aside from some changes in efficiency, process, and rhythm, my work and life have not been
+stirred much by AI.
+Value does not shift dramatically just because one or two tools are added.
+
+I do not plan to count how much code I generated with AI, or how many tokens or dollars I spent
+in the past year.
+But, rarely, this is a piece of writing typed 100% by me.
+
+The world is going through profound change.
+I am honored to be part of it, one wave among countless, breaking against a rock.

+
+如果 21 年的五一没有崴到脚，我可能也不会一路从湖仓一体云原生走到向量多模 AI Native。
+是的，2025 年是我在数据库行业摸爬滚打的第五个年头。
+又到写年终总结的时候了，虽然前段时间狠狠地搞了一下「岁月史书」，但是该有的仪式感还是要的。
+
+这次多谈谈自己。
+
+## 只是谈谈工作
+
+我还是在一家数据库公司工作。
+是的，「还是」意味着我又一次切换了工作。
+12 月底的时候，我加入 OceanBase 从事数据库和 AI 生态相关的开源工作，
+这已经是我职业生涯中的第三家数据库公司。
+
+当然，在 NebulaGraph 做 GraphRAG 占据了 2025 的绝大多数时间。
+尽管这个赛道已经过度拥挤并且不再火热，但我和团队里的其他同学在过去一年里还是交出了一份不错的答卷——
+在特定领域的客户评测中能够达到 95% 的准确率，
+总体开销也降低至可以对标向量全文混合索引，
+几乎为基于图的文档类 RAG 的广泛应用铺平了道路。
+
+至于工作派生出的产出也产生了一些积极的影响。
+比如在 3 月份我调研集成 MCP 的时候，
+设计和实现了 LlamaIndex 生态中的第一个 MCP 集成方案，
+并且以 llama-index-tools-mcp 的形式贡献给上游。
+在由社区进一步开发完善后，它成为了整个 Python 生态中下载量排在前 2% 的包。
+
+我算不上一个醉心工作和研究的人。
+若论代码品味，在过往共事过的同事中似乎也只算一般。
+即便这样的我，也可以发光发热。
+在 2025 年底的 NebulaGraph 社区评选中，也获得同事的肯定。
+非常感谢大家的提携和帮忙，尽管江湖路远，终究还是会有机会再见面。
+
+## 愿开源庇佑你我
+
+由于工作从事的 GenAI 平台是一个商业化产品，我参与开源的模式也发生了改变，
+更多时候会从需求调研和落地的角度做一些事情，
+前述的 llama-index-tools-mcp 就是这样的一个产物。
+
+当然，我围绕 coding agent 做过一些探索。
+参照 ampcode 的文章做了一个简单的 Python 实现，
+它的后续演进的一些探索成为了在 PyCon China 2025 上的分享
+《从 0 开始构建多 Agent 协作的命令行编程助手》的基石。
+
+作为演讲中的一个片段，我介绍了自己为 agent client protocol 做的 Python SDK。
+没有想过几个月后它会被 kimi-cli、openhands 等集成，
+并且最终成为官方 SDK 的一员，单月下载量过百万，我也多刷新出一个新的维护者的身份。
+
+我在 Apache 项目上也有一些投入。
+将 OpenDAL 的几个子项目从 Repo 中拆了出来，
+最近又在 DataSketches 的 Rust 实现上投入了一些无处安放的夜晚。
+
+开源是否有我并不见得会更好或更糟糕，但我确确实实会从中汲取养分和动力。
+哪些我曾经拥有过的美好一切，似乎就是在和开源伴生而来。
+尽管我还有太多承诺过的事情被抛在脑后，没有办法及时兑现。
+
+## 奔向更美好的生活
+
+今年最重要的改变是：由于年底换到杭州工作，我总算结束了长达 4 年的异地恋爱，在第 8 个年头。
+也解锁了更多和女朋友的美好的回忆，
+比如在邓紫棋的演唱会上练习金鱼嘴，在五月天的演唱会被 wmls 投喂物料。
+
+尝试通过学习来收获一些新技能。
+虽然现在也还只是停留看着谱子弹《兰花草》的水平，
+但至少又再一次能认得吉他和弦了。
+练习了一段时间 house 舞种，
+尽管跟上其他人的节奏对我已经是一个非常大的挑战，
+但跟着节奏摇摆总是能让心情得到放松。
+
+我有两只不那么可爱的猫咪。
+有段时间一到凌晨就会扒拉开门跑到我的身上蹦迪。
+坦白说，我没有把它们照顾很好。
+但是枸杞还是一如既往地向我展露它的小肚皮，
+芦荟在搬家到杭州以后也愿意偶尔凑过来吃一点点猫条。
+
+生活啊，生活呵。
+日日夜夜，但是提笔就不知道要写些什么了。
+过得还算安好，也无甚风雨。
+不久前的体检里似乎也没有再看到脂肪肝的影子。
+
+## 留一些笔墨给 AI
+
+除了一些效率、流程和节奏上的变化，我的工作和生活并没有因为 AI 而产生更多的波澜，
+毕竟价值并不会因为多了一两个工具的介入就发生显著的偏移。
+
+我没有打算统计我有多少代码是使用 AI 生成，过去一年到底花费了多少 token 或者费用。
+但是，难得地，这是一篇 100% 我手打的文字。
+
+世界在发生着深刻的变革，很荣幸能够参与其中，作为无数浪花中拍在石头上的一朵。
