API Retry Policy Design
Retry without causing storms
Designing retries means retrying only retryable errors, using exponential backoff with jitter, capping attempts, coordinating with idempotency keys, and surfacing Retry-After guidance to clients.

Classify
Retry transient errors/timeouts; avoid retrying 4xx logic errors.
Backoff
Use exponential backoff with jitter and caps on attempts/time.
Coordinate
Use idempotency keys; honor Retry-After; prevent thundering herd.

API Basics
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.
What it is
Blockchain
A blockchain is a distributed ledger secured by cryptography and consensus nodes.
