When to pick Weaviate
The most feature-rich open-source vector DB: hybrid BM25+HNSW, multi-tenancy, generative modules. Operationally heavier than kynetra.
- You need HNSW at scale past ~100k vectors — kynetradb uses brute-force today.
- Your team is already invested in Weaviate's SDK and ecosystem.
When to pick kynetradb
- You want a comparison-led conversation about BM25 full-text, vector evaluation, and data-plane trade-offs.
- You need a product-specific implementation scope rather than a generic migration claim.
- You want to assess 19 hosting target profiles, including 5 Indian providers.
- You want a scoped preview conversation about the data, deployment, and operating boundary.
- You want a single binary with no runtime dependencies — no container fleet to operate.
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.
