3Frameworks

Framework

How should the write path (URL creation) work?

Key generation strategy?

Base62 encoding: 7 chars = 3.5T unique keys

Pre-generated key pool avoids collision checks

Storage layer design?

100M URLs x 1KB avg = ~100GB — fits in single-node DB

Range-based sharding on short key for horizontal scale

How should the read path (redirect) work?

Caching strategy for hot URLs?

Redis/Memcached: 80/20 rule — 20% of URLs get 80% of traffic

Cache hit ratio target: 95%+

Redirect mechanism?

301 (permanent) vs 302 (temporary) — tradeoff: cacheability vs analytics

Non-functional requirements and tradeoffs?

Availability vs consistency?

AP system: eventual consistency acceptable for reads

99.99% uptime SLA = ~52min downtime/year

Rate limiting and abuse prevention?

Token bucket per API key: 100 creates/min default
