与此同时，上游原材料如锂、铝、铜以及内存芯片的价格上涨，增加了蔚来在成本端的压力。很快，蔚来在供应链端有了动作，与博世签署了全面战略合作协议，涵盖线控底盘、电池管理、制动控制、转向系统等核心技术领域，覆盖蔚来、乐道、萤火虫三大品牌。绑定全球头部零部件供应商，对蔚来而言有两层意义：一是在联合研发中优化成本、稳定供应，这对于正在努力降本增效的蔚来来说是实质性的帮助；二是为乐道和萤火虫这两个尚在建立影响力的子品牌，提供了技术层面的背书。

Documents of products collection are intentionally designed to be more complex and larger than accounts - I want to see what happens, what is the performance penalty mainly, once individual documents are stored on multiple database pages. In Postgres, page size is 8 KB by default - in practice, the goal is to have at least 4 rows stored on a single page, so every record that is larger than 2 KB is put on two or more disk pages. It obviously reduces performance for both writes & reads - more disk pages to read from and write to. In Mongo it works slightly differently in details, but essentially in the same vein - larger documents are stored on more than one page, degrading performance for all operations. In both cases we are about to see - how much exactly.
