TiDB 在国信证券海量数据高并发场景中的实践
作者介绍

陈培新，参与国信证券基础平台研发工作（DevOps、微服务治理、Serverless）

国信证券是一家全国性大型综合类证券公司，在 118 个城市和地区共设有 57 家分公司、185 家营业部，根据中证协发布的数据，近年来国信证券的总资产、净资产、净资本、营业收入、净利润等核心指标排名行业前列。

** A quick and dirty intro to the .pbm file format **
I’ve been fiddling with writing programs that draw pictures. I started with PostScript for this, but have since moved to writing programs that output in the .pbm format.
