System Design Concepts

Database Replication

Database Replication

Leader-Based Replication

Single-leader write path, follower catch-up, and failover

Replication Implementations

Statement-based, WAL shipping, row-based, and logical replication

Read Replicas & Replication Lag

Sync vs async replication, replication lag, read-your-writes, monotonic reads, and replica promotion

Replication Lag

Read-your-writes, monotonic reads, and consistent prefix reads

Consistency Models

Strong, eventual, causal, and linearizability
