Linux file real-time synchronization solution sersync and lsyncd

Introduction Real-time file synchronization is a very common requirement for operation and maintenance. For example, if a clustered machine needs to upload a file, the previous step is to upload it separately for each server. After synchronizing files, only upload one, and other machines will automatically synchronize. Currently, the mainstream solutions for achieving real-time synchronization […]

Use canal to achieve real-time data synchronization

canal canal [k?’n?l], translated as waterway/pipeline/ditch, its main purpose is to provide incremental data subscription and consumption based on MySQL database incremental log analysis In the early days of Alibaba, due to the deployment of dual computer rooms in Hangzhou and the United States, there was a business need for cross-computer room synchronization. The implementation […]

[Linux] Thread synchronization

Thread synchronization Threads are only mutually exclusive, which can ensure thread safety. However, this is unreasonable! If a thread competes for a lock, it can still compete for a lock after it is released. Because the CPU is executing the current thread at this time, the thread can continue to compete for the lock. This […]
