Can Cachee replace Memcached?

Yes. Cachee supports the Memcached protocol alongside full RESP (Redis protocol) with 133+ commands. You get everything Memcached offers — simple key-value caching — plus AI-powered pre-warming, multi-tier storage (L1/L2/L3), persistence, and richer data structures. Migration takes minutes.

How much faster is Cachee than Memcached?

Cachee L1 cache hits resolve in 1.5 microseconds — roughly 500,000x faster than a typical Memcached network roundtrip of ~1ms. Cachee also delivers 32M+ ops/sec on a single node compared to Memcached's ~100K ops/sec, and achieves a 99%+ hit rate through AI predictive pre-warming.

Does Memcached have CDC auto-invalidation?

No. Memcached has no built-in mechanism to watch database changes and invalidate keys automatically. You must manually delete or expire keys in application code when underlying data changes. Cachee's CDC auto-invalidation watches your database WAL and invalidates affected cache keys in under 1ms with zero application code.

Does Memcached support cache contracts?

No. Memcached provides no per-key SLAs, audit trails, or compliance guarantees. It is a simple volatile key-value store with no observability into individual key behavior. Cachee's cache contracts let you set per-key SLAs that are SOC 2, FINRA, and HIPAA auditable.

Does Memcached have a causal dependency graph?

No. Memcached treats every key as independent — there is no way to express that key A depends on key B. When key B changes, you must manually find and invalidate all dependent keys. Cachee's causal dependency graph uses DEPENDS_ON declarations for automatic transitive invalidation across the entire key graph.

Key insight: Cachee isn't competing with Memcached — it replaces the need for it. Deploy Cachee on top of your existing backend and get AI-powered caching with richer data structures, persistence, and sub-microsecond hits.

Where Cachee Wins

Use Case	Why Cachee Wins
Session Caching	Sub-microsecond session lookups with persistence. Sessions survive restarts — no more lost carts or re-logins.
API Response Caching	AI pre-warms popular endpoints before traffic spikes. 99%+ hit rate vs Memcached's TTL-based ~85-90%.
ML Feature Stores	Rich data structures (hashes, sorted sets) for feature vectors. Memcached's flat key-value can't express complex feature schemas.

Use Case

Why Cachee Wins

Session Caching

Sub-microsecond session lookups with persistence. Sessions survive restarts — no more lost carts or re-logins.

API Response Caching

AI pre-warms popular endpoints before traffic spikes. 99%+ hit rate vs Memcached's TTL-based ~85-90%.

ML Feature Stores

Rich data structures (hashes, sorted sets) for feature vectors. Memcached's flat key-value can't express complex feature schemas.

Where Memcached still works: Memcached is simple, proven, and well-understood. For basic volatile key-value caching at smaller scale with no need for persistence or advanced data structures, Memcached remains a solid choice. But once you need AI warming, multi-tier storage, or richer commands — Cachee is the upgrade.
