Is Cachee a KeyDB replacement?

Cachee isn't a KeyDB replacement — it's an intelligence layer. Cachee deploys as an AI-powered L1 cache on top of KeyDB. Your KeyDB instance handles writes and serves as L2 storage with its multi-threaded architecture, while Cachee delivers reads at 31ns with predictive pre-warming and 99%+ hit rates.

How much faster is Cachee than KeyDB?

Cachee L1 cache hits resolve in 31ns from in-process memory. KeyDB, despite its multi-threaded improvements over Redis, still requires a network roundtrip at ~150µs. Cachee is ~100× faster for cached reads. Combined, Cachee L1 + KeyDB L2 gives you the best of both worlds.

Does KeyDB support AI cache warming or predictive caching?

No. KeyDB is a multi-threaded data store focused on throughput, not intelligence. It doesn't analyze access patterns, predict future requests, or pre-warm keys. Cachee's AI engine monitors access patterns in real-time and pre-fetches data before your application needs it, pushing hit rates from ~85% to 100%.

How much does KeyDB cost compared to Cachee?

KeyDB is open-source but requires self-hosting. A production KeyDB deployment on AWS (c5.xlarge, EBS, monitoring, backups) runs $280+/month plus engineering time for operations, patching, and on-call. Cachee's Scale plan is $149/month — fully managed, AI-optimized, with built-in monitoring and zero ops.

Can I use Cachee with KeyDB?

Yes — this is the optimal architecture. Cachee sits as an L1 layer in front of KeyDB. Reads hit Cachee at 31ns with AI pre-warming. Cache misses fall through to KeyDB's multi-threaded backend. You get sub-microsecond reads plus KeyDB's write throughput, with zero application code changes.

Does KeyDB have CDC auto-invalidation?

No. KeyDB is a Redis fork focused on multi-threading, not database-aware invalidation. It has no mechanism to watch database WAL streams and invalidate cache keys when underlying data changes. Cachee's CDC auto-invalidation watches your database and invalidates affected cache keys in under 1ms with zero application code.

Does KeyDB support cache contracts?

No. KeyDB, like Redis, provides no per-key SLAs or compliance audit trails. It offers basic monitoring metrics but no contractual guarantees on individual key freshness or correctness. Cachee's cache contracts let you define per-key SLAs that are SOC 2, FINRA, and HIPAA auditable.

Does KeyDB have a causal dependency graph?

No. KeyDB treats all keys independently with no dependency tracking. Invalidating a parent key does not cascade to derived keys. Cachee's causal dependency graph uses DEPENDS_ON declarations so that when a source key changes, all transitively dependent keys are automatically invalidated.

Threading isn't the bottleneck: KeyDB's multi-threading improves Redis throughput by 5x. But throughput isn't latency. Every KeyDB read still crosses the network at ~150µs. Cachee's in-process L1 serves at 1.5µs — 100x faster — then falls through to KeyDB on miss.

Migration: Layer Cachee on Top of KeyDB

Zero-change deployment: Deploy Cachee as an L1 layer on top of KeyDB: Point Cachee's upstream at your KeyDB instance. Reads hit Cachee's L1 at 1.5µs. Misses fall through to KeyDB. KeyDB's multi-threaded throughput handles writes and L2 reads. Zero changes to your application code.
