Which replication model has the strongest resiliency power?
Master-Slave Replication model has the strongest resiliency power:
- With the master-slave distribution, you replicate data across multiple nodes. One node designates master, the other as slave.
- This master might be an authoritative source for data and responsible for processing any updates to that data.
- The main advantage of master-slave replication is read resilience: if the master fails, the slaves can still handle read requests.
- The failure of a master does eliminate the ability to handle writes until either the master is restored or a new master is appointed.
