Overview
The Sync package provides basic synchronization primitives, such as mutex locks. In addition to the once and waitgroup types, most are suitable for low-level program threads, with high levels of synchronization using channel communication better.
The value of the type of this package should not be copied.

The main function of cond is to acquire a lock, and the Wait () method waits for a notification to proceed with the next lock release, which controls the appropriate release of the lock, the release frequency, and the wait and notification for goroutine in the concurrency environment.

Microsoft sync framework is a fully functional synchronization platform that enables collaboration and offline access between applications, services, and devices.
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

If you are a maintenance engineer, you are likely to face dozens of, hundreds of or even thousands of servers, in addition to bulk operations, environmental synchronization, data synchronization is also essential skills.
When it comes to "sync," the weapon that has to be mentioned is rsync, and today is the art of sync I see in this tool.

We often use rsync in this way:

Traditional UNIX has 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.

First, let's take a simple example: if a large production enterprise contains two subsystems:
-There is a product production system deployed inside the Enterprise. Employees (production employees) working inside the enterprise can access the system through the Intranet. The background database is SQL Server 2008 R2 in the LAN.
-Another product inventory system is run on the Windows azure platform. Employees outside the company, such as sales personnel, can quickly access the company through

Explanation:
Rpl_semi_sync_master_enabled is used to control whether the Master node enables semi-synchronization. If it is enabled or not, it is set to ON or OFF (1or0 ).
Rpl_semi_sync_master_timeout is to control how long the Master waits to be notified that Slave has received the time-out.
Rpl_semi_sync_slave_enabled controls whether or not Slave enables semi-synchronization. If it is enabled or not, it is set to ON or OFF (1or0 ).
Monitor status variables of semi-synchronous
