Differences between Master-Slave Replication and Master-Master Replication
Below are the differences between Master-Slave Replication and Master-Master Replication:
Aspect | Master-Slave Replication | Master-Master Replication |
---|---|---|
Data Flow | One-way: from master to slave | Bi-directional: between masters |
Write Operations | Only master allows writes; slaves are read-only | Both masters allow writes |
Read Operations | Slaves can handle read operations | Both masters can handle read operations |
Data Consistency | Asynchronous, potential delay in consistency | Can be synchronous, immediate consistency possible |
Conflict Resolution | Simpler, conflicts less likely due to one-way flow | More complex, conflicts may occur and need resolution |
Types of Database Replication
Database replication is like making copies of your important documents so you have backups in case something happens to the original. There are different ways to make these copies, like having one main copy (master) that gets updated and then making copies (slaves) of that updated version. Another way is to have multiple main copies (masters) that can all be updated and share those updates. In this article, we will see different types of database replication.
