Is Cachee an ElastiCache replacement?

Cachee deploys on top of ElastiCache as an AI-powered L1 caching tier. It doesn't replace ElastiCache — it enhances it with 500,000x faster cache hits, AI pre-warming, and multi-tier optimization. Your ElastiCache cluster stays as-is.

How much cheaper is Cachee than ElastiCache?

Cachee's AI-driven cache optimization typically reduces total infrastructure costs by 40-70%. Higher hit rates mean fewer cache misses falling through to your database, reducing both ElastiCache node count and database load.

Does ElastiCache support CDC auto-invalidation?

No. ElastiCache is a managed Redis/Memcached service, but it has no database change-data-capture integration. You must build invalidation logic in your application or set conservative TTLs and accept stale data. Cachee's CDC auto-invalidation connects to your database WAL (including RDS PostgreSQL and Aurora) and invalidates affected cache keys in under 1ms — no Lambda functions, no EventBridge rules, no application code. This fills a gap that AWS has never addressed in ElastiCache.

Does ElastiCache have in-process vector search?

No. ElastiCache offers managed Redis, which recently added Vector Sets in Redis 8, but ElastiCache version availability lags behind open-source releases. Even when available, all queries require a network roundtrip (~200µs same-AZ). Cachee runs HNSW vector search in-process at 0.0015ms — 660x faster. For AI/ML workloads on AWS, Cachee eliminates the ElastiCache network hop entirely.

Does ElastiCache support cache contracts with SLA guarantees?

No. ElastiCache provides TTL-based expiration and CloudWatch metrics, but no per-key freshness SLAs, compliance audit trails, or contract enforcement. AWS shared responsibility means you're accountable for cache correctness. Cachee cache contracts let you define enforceable freshness guarantees per key pattern with audit logs suitable for SOC 2, FINRA, and HIPAA — filling the compliance gap that ElastiCache leaves to your application layer.

Can ElastiCache detect cache poisoning?

No. ElastiCache stores and serves whatever your application writes. AWS offers no built-in mechanism to detect corrupted or stale cache entries — you'd need to build custom validation with Lambda and CloudWatch, adding latency and cost. Cachee's self-healing consistency system validates cached data against source-of-truth checksums, detects drift or poisoning, auto-repairs affected keys, and provides a real-time consistency score — all without additional AWS services.

Does ElastiCache have a causal dependency graph?

No. ElastiCache treats every key independently — there's no way to express that invalidating one key should cascade to related keys. Building dependency tracking on ElastiCache requires custom application logic, often involving DynamoDB or another service to store relationships. Cachee's causal dependency graph supports native DEPENDS_ON declarations with transitive invalidation. When a parent key changes, all downstream dependents are automatically cleaned — no extra AWS services required.

Migration: Keep ElastiCache Running

Zero-risk migration: Cachee deploys as an L1 tier in front of ElastiCache. Your ElastiCache cluster stays exactly where it is. Cachee intercepts reads at 1.5µs and falls through to ElastiCache on cache miss. You can scale down ElastiCache nodes as Cachee absorbs the load — or keep them as a safety net. Either way, you're faster from minute one.
