.Net Core3.0 WebApi 项目框架搭建 十七:使用NewLife.Redis替换掉原来的Redis

 

 .Net Core3.0 WebApi 项目框架搭建:目录

 

介绍

  • NewLife.Redis主要作者及经验介绍来源:大石头
  • 源码: https://github.com/NewLifeX/NewLife.Redis
  • Nuget:NewLife.Redis
  • NewLife.Redis是一个Redis客户端组件,以高性能处理大数据实时计算为目标。
  • Redis协议基础实现Redis/RedisClient位于X组件,包含基础字符串操作。完整实现由独立开源项目NewLife.Redis提供。NewLife.Redis为扩展实现,主要增加列表结构、哈希结构、队列等高级功能。
  • 采取连接池加同步阻塞架构,具有超低延迟(200~600us)以及超高吞吐量的特点。在物流行业大数据实时计算中广泛应有,经过日均100亿次调用量验证。

特性

  • 在ZTO大数据实时计算广泛应用,200多个Redis实例稳定工作一年多,每天处理近1亿包裹数据,日均调用量80亿次

  • 低延迟,Get/Set操作平均耗时200~600us(含往返网络通信)

  • 大吞吐,自带连接池,最大支持1000并发
