What you'll learn

High availability needs proactive replication planning; reacting after failure is too late to protect data and continuity.
Physical replication slots ensure reliable streaming by preventing WAL loss and maintaining data flow during outages.
Monitoring replication lag is vital; keeping it under 5 seconds enables near real-time access on read replicas.
Database replication is not just backup strategy but a core architecture decision that enables both disaster recovery & read scaling capabilities.
