A tool to test Tair GDN sync latency.

Project description

Tair 全球多活 延迟测试工具

本工具用于测试 Tair 全球多活功能的同步延迟。

测试方法:

  1. 在源端 set key value,写入的 value 为写入时间戳。
  2. 在目的端读取 value 计算同步延迟,并生成统计数据和图表。

注意事项:

  1. 测试期间会清空实例数据,请使用测试实例完成本测试。
  2. 请使用标准版(主从版)实例测试。

安装

需要 Python 3.9 或更高版本,通过 pip 安装

pip install tairgdn-latencytest

快速开始

测试流程

请确保以以下顺序执行:

  1. 先在目的端执行
tairgdn-latencytest read [-h host] [-p port] [-u username] [-a password] [-n request_count]
  1. 然后在源端执行
tairgdn-latencytest write [-h host] [-p port] [-u username] [-a password] [-l length] [-n requests] [-P pipeline] [-c connection]
