|
||||
- **Failover Time:** <5 minutes
|
||||
|
||||
#### Database Failover
|
||||
- **Mechanism:** PostgreSQL streaming replication
|
||||
- **Configuration:** Primary + 2 standby replicas
|
||||
- **Failover Trigger:** Automated via Patroni
|
||||
- **Failover Time:** <2 minutes
|
||||
|
||||
#### Redis Failover
|
||||
