What Is Replication in Databases?

Learn about database replication, a process of copying data across multiple nodes to enhance availability, distribute load, and reduce latency. Discover different replication types including full, transactional, snapshot, merge, and key-based incremental replication. Understand replication challenges and how replication logs like WAL shipping and logical replication maintain data consistency. This lesson equips you with knowledge of replication strategies and their impact on distributed database systems.
