Request Timeline (5-second intervals)
Aggregated view of requests over time - each bar represents a 5-second period
Rate Limit Remaining
Exponential Backoff: Double the delay each time - Delays grow: 1s → 2s → 4s → 8s → 16s → 30s (max)
Understanding Rate Limiting
What you'll learn
- How rate limiting protects APIs from abuse
- Different backoff strategies and when to use them
- Reading and understanding rate limit headers
- Handling HTTP 429 responses gracefully
- Optimizing request patterns for better throughput
- Real-world API rate limiting examples
Backoff strategies
- Fixed Delay: Simple but can cause thundering herd.
- Linear Backoff: Predictable increase in delay.
- Exponential Backoff: Rapidly reduces load on servers.
- Jittered Exponential: Prevents synchronized retries.
Pro tips
- Always implement exponential backoff with jitter for production systems.
- Monitor rate limit headers to anticipate throttling before it happens.
- Use circuit breakers to prevent cascading failures.
- Consider different rate limits for different user tiers (free vs paid).
