What are the best database replication strategies?

There are several effective database replication strategies, including master-slave replication, multi-master replication, and peer-to-peer replication. Each has its own advantages and use cases.

Can you explain master-slave replication?

Sure! In master-slave replication, one database server (the master) handles all write operations, while one or more slave servers replicate the data from the master and handle read operations. This helps in load balancing and data redundancy.

What are the drawbacks of using master-slave replication?

Some drawbacks include potential bottlenecks at the master server, increased complexity in failover scenarios, and possible data lag between the master and slaves.

How does multi-master replication work?

In multi-master replication, multiple database servers can accept write operations, and changes are synchronized across all nodes. This improves availability but can lead to conflicts that need resolution.

Which strategy is best for high availability?

For high availability, multi-master replication is often preferred, as it allows for continuous operation even if one node fails.
