Use pt-table-sync to restore inconsistent data
In the previous article, pt-table-checksum was used to verify data consistency. This section describes how to verify master-slave data consistency. when determining whether master-slave data is inconsistent, you must consider how to fix it. We recommend another important tool of percona-toolkit: pt-table-sync.

The Linux Sync command is used for data synchronization, and the Sync command is used when shutting down the Linux system.The Linux system to write to the hard disk data sometimes will be more efficient, will write to filesystem buffer, this buffer is a memory space, if you want to write to the hard disk data in this buffer, and the system suddenly power down, then the data will be lost, The
The Svnsync can easily synchronize another source SVN version to the specified repository, providing convenience for multi-version library applications.Example: (The repository is stored under directory/svn/)Source Version library: svn://196.168.0.1/testa Sync User:sync_source Password:123456Target repository: svn://196.168.0.2/testb Sync User:sync Password:123456The source repository is used to develop app
In Java, the Synchronized keyword is used to control thread synchronization, that is, in a multithreaded environment, control synchronized code snippets are not executed concurrently by multiple threads. Synchronized can either be added to a piece of code or added to a method.The point is, don't think it's all right to add synchronized to a method or snippet, and look at the following code:Class Sync {public synchronized void Test () {System.out.print

Database Synchronization Overview

Sync Framework supports synchronization between databases. It provides an intuitive and flexible API that allows you to generate applications for offline and collaborative solutions. With this API, you can use all or part of the provided components to complete synchronization based on the application architecture and requirements. Sync Framework supports client-ser

One of the benefits of signing in to your PC with a Microsoft account is that you can sync information between any computers that you use and that are also running Windows 8.1 or Windows RT 8.1. When you sign in with a Microsoft account, your PC connects online to a Microsoft server or to the cloud. This means that your personal settings and preferences will be stored in SkyDrive and will be synced to any computer you sign in to. For exampl
Microsoft sync framework is a fully functional synchronization platform that implements applications.Program, Service and device collaboration and offline access. It provides some technologies and tools that support roaming, sharing, and obtaining data offline. By using the sync framework, developers can build a synchronization ecosystem to integrate any application with any data in any storage using any pr
After the Sync command starts the unix system with the reboot command, the system prompts an error message. Some applications cannot work normally. After carefully checking the system files and comparing them with the initial correct backup, we found that some files were indeed damaged and we could not find the cause of the file being damaged, finally, I thought of writing the cache command-sync.

In the previous section, we said that knowledge is the metadata (metadata) in Microsoft sync framework. This metadata is used to describe all changes applied to replica. These changes are either direct, or through synchronization.
MSF uses knowledge to enumerate changes and conflict detection.
Change enumeration and Conflict Detection generally compare the versions of the same item in two copies. A typical practice is that destination sends the ve

Traditional UNIX implementations have a buffer cache or page cache in the kernel, and most disk I/O is buffered. When writing data to a file, the kernel usually copies the data into one of the buffers, and if the buffer is not yet full, it is not queued to the output queue, but waits for it to be full, or when the kernel needs to reuse the buffer to hold other disk block data, then the buffer is queued to the output queue, and then when it arrives at the first To perform the actual I/O operation
