Also known as: database replication, data sync

Last updated August 8, 2026

Definition

Replication copies data from one database system to another so reads can scale, failovers are possible, or geographic copies stay roughly in sync.

Real-World Example

A popular app may replicate its database to a secondary region so users still read data if the primary region has an outage.
