From 9bda0b39a0f589937ae9f665dd7b01fdf1e6b5e3 Mon Sep 17 00:00:00 2001 From: Bo Xiao <69349626+boxiaobj@users.noreply.github.com> Date: Thu, 3 Sep 2020 08:53:16 +0800 Subject: [PATCH] Modify wallevel description in section 2 of Master/Slave vnode writing process MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 修改了Master/Slave vnode 的第二段关于wallevel和日志文件WAL的描述:如果系统配置参数walLevel大于0,vnode将把该请求的原始数据包写入数据库日志文件WAL。如果walLevel设置为2,而且fsync设置为0,TDengine还将WAL数据立即落盘,以保证即使宕机,也能从数据库日志文件中恢复数据,避免数据的丢失; --- documentation20/webdocs/markdowndocs/architecture-ch.md | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/documentation20/webdocs/markdowndocs/architecture-ch.md b/documentation20/webdocs/markdowndocs/architecture-ch.md index 7ab4b5d096..a279875649 100644 --- a/documentation20/webdocs/markdowndocs/architecture-ch.md +++ b/documentation20/webdocs/markdowndocs/architecture-ch.md @@ -162,7 +162,7 @@ Master Vnode遵循下面的写入流程:
