The first step, we open the Assistant, and then click on the interface in the upper-right corner of "Three horizontal" select "Address Book collation" details as shown in the following figure.
The second step, and then in the open Address Book, we find inside the "empty Address Book", click "Empty the entire computer contact", click "completely delete" on it.
The third step, OK now we are in the QQ assistant these people deleted.
Haha, QQ
As a result of work learning needs, many friends often use more than just a computer, if a computer collection of bookmark pages one by one to add to other computers, will be a very troublesome thing, Firefox Firefox bookmark synchronization function can conveniently help us to sync bookmarks data offsite, Here's how to use Firefox Firefox bookmark sync (take the latest Firefox4 as an example):
entire process is as shown.
This solution still has the following problems
1. 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 back
2. Once a rollback occurs, the business cannot meet the needs of 0 downtime
Summarizing the processes and known issues of the three blue-green deployments above, you can conclude that the key requirements for a blue-green deployment are:

Mysql5.5 semi-sync replication installation and maintenance
MySQL's replication protocol is asynchronous. Although asynchronous efficiency and performance are good, it cannot guarantee master-slave data consistency (if the master crash, transactions that have been committed will not be transferred to any slave.) from mysql5.5, MySQL introduces the semi-sync function to ensure d
The Sync Framework is a full-featured synchronization platform that enables collaboration and offline access to applications, services, and devices. The Sync Framework provides some technologies and tools to support roaming, sharing, and fetching data while offline. By using the sync Framework, developers can build synchronous ecosystems that integrate arbitrary

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
