Description
请问下我们的业务场景最大的表差不多需要10亿这种量级的子表，qps大概是30w/s，数据一分钟上报一次，这种场景下需要的服务器资源大概需要多少啊，要如何估算，特别是cpu和内存这块，按照官方文档，好像是一个vnode可以管理100万个子表，一个vnode差不多核cpu的配比是1：1？那么十亿差不多要一千核，这样看下来要的cpu核数太多了，不知道有没有什么优化手段？

Research direction
Start with the official documentation on vnodes, subtable limits, CPU allocation, and cluster sizing, then relate those figures to the stated billion-subtable, 300k-QPS, once-per-minute workload. Done means providing a scenario-specific CPU and memory estimation and identifying any documented optimization guidance.
