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。
国信证券从 2020 年 6 月开始接触 TiDB,从技术预研到第一个业务上线大约花了半年时间。第一个上线的业务是金太阳帐单,后面陆续在数据中台、服务观测等系统中应用。从只在东莞主机房的 TiDB 部署到 2021 年 9 月实现 TiDB 多机房的部署,并启动国产海光 x86 服务器的试点工作,国信证券在开源 NewSQL 数据库的探索和应用层面,积累了丰富的实践经验。目前, 国信证券共有 7 个 TiDB 集群,节点数量 109 个,最大表 100 亿,支撑了托管、经纪和自营等业务。

从 CPU 角度理解 Go 中的结构体内存对齐
大家好,我是 Go 学堂的渔夫子。今天跟大家聊聊结构体字段内存对齐相关的知识点。
原文链接: https://mp.weixin.qq.com/s/H3399AYE1MjaDRSllhaPrw
大家在写 Go 时有没有注意过,一个 struct 所占的空间不见得等于各个字段加起来的空间之和,甚至有时候把字段的顺序调整一下,struct 的所占空间又有不同的结果。
本文就从 cpu 读取内存的角度来谈谈内存对齐的原理。
01 结构体字段对齐示例
我们先从一个示例开始。T1 结构体,共有 3 个字段,类型分别为 int8,int64,int32。所以变量 t1 所属的类型占用的空间应该是 1+8+4=13 字节。但运行程序后,实际上是 24 字节。和我们计算的 13 字节不一样啊。如果我们把该结构体的字段调整成 T2 那样,结果是 16 字节。但和 13 字节还是不一样。这是为什么呢?

f1 int8 // 1 byte
f2 int64 // ... ⌘ [Read more](https://gocn.vip/topics/20967)```

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.
My goal here is to write noise to a .pbm file.
A .pbm file is the lowest common denominator among image file formats.

只有天空才是你的极限,我们热爱探索的过程并沉浸其中
Hackathon 本身带给我们的是一次全新的探索,并不只是一队人有一个明确的目标,花几天时间写代码,那其实是很无聊的。探索的本身让我们发现,越探索越能找到更新、更好、更优雅的解决办法,我们热爱这个探索的过程并沉浸其中…… —— TiMatch 赛队
战队成员之一柏佳辰是一个爱画画、爱摩托车、喜欢读《理想国》,建筑学出身的程序员。
在 TiDB Hackathon 2020 赛事中,TiGraph 项目在 TiDB 中实现了一套新的 Key-Value 编码来引入图模式,处理传统关系型数据库难以覆盖的图数据分析场景,实现了 TiDB 在四度人脉的计算性能大幅提升,夺得了二等奖。
