I. OverviewThe master-slave replication policy of Redis is implemented by its persisted RDB file, which is the process of dump the Rdb file, transfer the Rdb file to slave, and then synchronize the operation of the dump to slave in real time. Make the

MySQL supports unidirectional and asynchronous replication. During the replication process, a Linux server acts as the master server, and one or more other servers act as slave servers. The master server writes updates to binary log files. MySQL supports unidirectional and a

parent process. The parent process then writes the cached write command to the temporary file as well; Now the parent process can replace the old aof file with the temporary file and rename it, and the subsequent write commands are appended to the new AoF file. The two persistence modes have their own characteristics, fast photography has little impact on performance, but once the crash, the data loss is large, and the AOF data security is high, but the performance impact is large, thi

Although Redis has excellent performance, we can still master/slave this simple architecture, read and write separation, further mining redis performance, improve system availability. How does Redis perform master-slave replication? Redis
