Is Cachee a Valkey replacement?

No — Cachee enhances Valkey. Cachee deploys as an AI-powered L1 caching layer on top of Valkey. Your Valkey instance stays as your open-source L2 data store, while Cachee adds 31ns in-process reads, predictive pre-warming, and 99%+ hit rates. Together they form the fastest open-source caching stack available.

How much faster is Cachee than Valkey?

Cachee serves cached data in 31ns from in-process L1 memory. Valkey, like Redis, requires a network roundtrip at ~1ms for typical deployments. Cachee is approximately 500,000x faster for cached reads. Combined as L1+L2, you get sub-microsecond hits with Valkey's full Redis compatibility as the storage backend.

Does Valkey have AI-powered cache warming?

No. Valkey is a data store, not an intelligent caching layer. It stores and retrieves data but doesn't predict access patterns, pre-warm keys, or optimize eviction using machine learning. Cachee's AI engine analyzes request patterns in real-time and pre-fetches data before it's needed, achieving 100% cache hit rates versus Valkey's typical 85-92%.

How much does Valkey cost compared to Cachee?

Valkey is free and open-source (BSD-3 license). However, production deployment requires infrastructure: EC2 or equivalent ($150-300/month), monitoring, HA configuration, backups, and operations time — totaling $250+/month. Cachee's Scale plan at $149/month is fully managed with AI optimization included. Many teams use both: free Valkey as L2, Cachee as managed L1.

Can I use Cachee with Valkey?

Yes — Cachee + Valkey is the recommended open-source stack. Point Cachee's upstream at your Valkey cluster. Cachee serves L1 reads at 31ns with AI pre-warming. Cache misses fall through to Valkey over the RESP protocol. No vendor lock-in on either layer — Valkey is BSD-3, Cachee supports any Redis-compatible backend.

Does Valkey support CDC auto-invalidation?

No. Valkey, as a Redis fork, requires manual invalidation — your application must DEL or EXPIRE keys when the database changes. Valkey inherits Redis's client-side tracking notifications, but these only notify connected clients of key changes within Valkey itself — they don't watch your source database. Cachee's CDC auto-invalidation monitors your database WAL (Postgres, MySQL, MongoDB) and invalidates affected cache keys in under 1ms with zero application code.

Does Valkey have in-process vector search?

No. Valkey is focused on being a stable, open-source Redis-compatible data store. It has no vector search capability. Cachee provides in-process HNSW vector search at 0.0015ms — running entirely within your application's memory. Even if Valkey adds vector modules in the future, the network roundtrip (~1ms) would make it 660x slower than Cachee's in-process approach.

Does Valkey support cache contracts with SLA guarantees?

No. Valkey uses the same TTL-based expiration as Redis — keys expire after a fixed time with no per-key freshness SLAs or compliance audit trails. Cachee cache contracts let you define enforceable freshness guarantees per key pattern with audit logs suitable for SOC 2, FINRA, and HIPAA compliance. Valkey's open-source governance is excellent for avoiding vendor lock-in, but it offers no compliance tooling for regulated industries.

Can Valkey detect cache poisoning?

No. Valkey stores and serves whatever is written to it, with no data integrity validation layer. Cachee's self-healing consistency system continuously validates cached data against source-of-truth checksums, detects drift or poisoning, auto-repairs affected keys, and exposes a real-time consistency score. For Valkey deployments in production, Cachee adds the data integrity guarantees that an open-source KV store inherently lacks.

Does Valkey have a causal dependency graph?

No. Valkey treats every key as independent — there's no built-in way to express that invalidating one key should cascade to others. Cachee's causal dependency graph supports DEPENDS_ON declarations with transitive invalidation. When a parent key is invalidated, all downstream dependents are automatically cleaned. This is a feature that no Redis fork, including Valkey, has implemented because it requires an intelligent caching layer, not just a data store.

Great foundation, smarter layer: Valkey is a great foundation — truly open-source, Linux Foundation governance, full Redis compatibility. But it's still a network-hop data store with static TTL eviction. Cachee layers AI intelligence on top: predicting access patterns, pre-warming hot keys, and serving reads 500,000x faster from L1 memory.
