Database Connection Failover Basics
Handle DB failover smoothly
Preparing for DB failover means using connection pools with health checks, retry/backoff on transient errors, DNS/endpoint strategies for new primaries, and testing failover to avoid long outages.

Detect
Use health checks/driver signals to detect role changes.
Retry
Implement backoff retries on transient errors; avoid hot loops.
Reconnect
Use DNS/cluster endpoints; test failover and pool refresh.

APIs let software request data or actions from other systems through defined endpoints and responses.
Comparison
RAM vs Storage
RAM handles what your device is actively working on, while storage keeps apps, files, and system data available over time.
How it works
Global Positioning System
GPS uses timing signals from satellites to calculate a receiver's position on Earth.
