kynetradb
One Rust binary: BM25 search + vector + KV + document + auth + files + realtime + agentic admin.
vs
Redis
In-memory KV store with optional modules: RediSearch (BM25) and Redis Vector (HNSW).
Feature comparison
| Dimension | kynetradb | Redis |
|---|---|---|
| Full-text search | BM25 (parallel, 1.07 ms @ 100k) | BM25 |
| Vector search | Brute-force cosine (2.21 ms @ 100k, no HNSW yet) Redis uses HNSW which scales better past ~100k vectors | HNSW |
| Auth | Built-in (bcrypt + JWT, 3 roles) | Built-in |
| File storage | Built-in (local + S3-compatible, SigV4) | None |
| Realtime | SSE (topic + kind filters) | polling |
| KV lookups | Yes (point lookup by ID) | Yes |
| Document filter | Yes (JSON predicates) | Yes |
| LLM runtime | Yes (Anthropic + OpenAI + Ollama) | No |
| Outbound DB sync | Yes (12 sinks: Postgres, DynamoDB, BQ, Firestore, CF, Mongo, Redis, Pinecone) | No |
| Self-host | Yes (single binary) | Yes |
| Single binary | Yes | Yes |
| License | Apache-2.0 | RSAL |
| Deploy targets | 18 (1-click) | 0 (1-click) |
| Free tier | Yes — Apache-2.0, self-host free | yes — Redis Cloud 30 MB |
When to pick Redis
Sub-millisecond KV at scale is Redis's home turf. For pure speed-of-read caching, nothing beats it. The license changed from BSD to RSAL in 2024.
- You need unlimited horizontal scale for a single access pattern.
- Your team is already invested in Redis's SDK and ecosystem.
When to pick kynetradb
- You need BM25 full-text + vector similarity + auth + files + realtime in one process — no external services.
- You want to deploy to 18 targets (including 5 Indian providers) from one Dockerfile.
- You need outbound sync to 12 databases (Postgres, DynamoDB, BigQuery, Firestore, Cloudflare, MongoDB, Redis, Pinecone) with zero extra code.
- You want an agentic admin with 10 typed LLM-driven actions and a persisted audit trail.
- You want Apache-2.0 with a self-host path that doesn't require an ops team.
Vector upsert + query — both APIs side by side
Upsert an embedding and query nearest neighbours. These are documentation-accurate shapes, not runnable end-to-end examples.
