First, IntroductionPt-table-checksum is one of the Percona-toolkit series tools that can be used to detect the consistency of the data in the master and from the database. The principle is to run on the Main library, checksum the synchronized tables and record them. It then compares the checksum of the main table to determine whether the data is consistent . The detection process in blocks, for large tables can be differentiated into multiple blocks, so as to avoid the lock table (according to a

(formerly Blue Stack staging) is destroyed when the new blue stack runs stablyThe entire process is as shown.This solution still has the following problems1. Although there is no longer a risk of polluting real-world data, the transaction data for the corresponding time period will still be lost when the release is rolled back2. Once a rollback occurs, the business cannot meet the needs of 0 downtimeSummarizing the processes and known issues of the three blue-green deployments above, you can co

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. Percona-toolkit installation and introduction Perco

Background Sync is Google's new web API that can delay sending user behavior until the user's network connection is stable. This helps to ensure that the data that the user wants to send is the actual data sent.The problems that exist todayNetwork is the most time to kill users, time wasted on the network waiting for page loading, Web page rendering and other loading data aspects.

Write Cache command--syncAfter starting the UNIX system with the reboot command, the system prompts for an error message and some applications do not work correctly. After careful examination of the system files, and compared with the initial correct backup, found that some files are really destroyed, and can not find the cause of the file corruption, and finally think of the write Cache command--sync, before reboot run

Write Cache command--sync After starting the UNIX system with the reboot command, the system prompts for an error message and some applications do not work properly. After careful examination of system files, and the initial correct backup to compare, found that some files are indeed corrupted, toss and turn to find the cause of the file is destroyed, and finally thought of the write Cache command--sync,

written data volume and the status of the I/O data buffer. although the time interval for non-synchronization is very short, if the power is down or the system crashes during this period, the written data cannot be written to the disk and will be lost. Note: The kernel "writes" the data in the buffer zone to the standard input disk file. Here "write" is not to move the data in the buffer zone to the disk file, but to the disk file, in this case, a backup of the buffer content is retained in the

The 'Log file sync' wait event in the RAC database is more complex than the 'Log file sync' wait event in the Standalone Database, mainly because the RAC database needs to synchronize the SCN to all instances. The 'Log file sync' wait event in the standalone database. When the user session is committed (commit), the user session will notify the LGWR process to wr

Often find good web sites on the Internet, the common practice is that we use favorites to save their own computer. Because the data for your favorites is stored locally, you cannot use Web site addresses that are stored in favorites on your local computer when you are on a business trip or when browsing a Web site using a browser on someone else's computer. In order to solve this problem, people will choose to use the network favorites, network favorites use more trouble. If you use Firefox to

Sync framework 2.1 introduces new features that allow you to synchronize SQL Server or SQL Server compact databases on your computer with SQL azure databases. This release also introduces parameter-based filtering and the ability to delete synchronization scopes and templates from databases, and enhances performance to accelerate and simplify the synchronization process.SQL azure Synchronization With sync f

Database Synchronization Overview 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

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
