There isn't a limit or performance metric we don't think we can improve by an order of magnitude when prioritized! If you expect to brush up against a limit or are limited by performance by an operation, contact us. Often can be fixed in days.
| turbopuffer excels at | turbopuffer may not currently be the best fit for |
|---|---|
| Large scale (1B+ documents/vectors) with lots of namespaces (tens of millions) | Large namespaces (100M+) |
| Naturally sharded data (e.g. B2B where each tenant's data is isolated in its own namespace) | Low scale, free tier |
| Cost-effectiveness | Aggregation (e.g. group by, sums, explore clusters, ...) |
| Fast cold starts | Single-digit millisecond latency (tpuf is currently low double digits) |
| Reliability | Extensive 1st-stage ranking (we encourage generating a candidate set with hybrid search and refining/re-ranking further in your own 2nd stage) |
| Hybrid search (BM25 + vector search) | Built-in re-ranking (we encourage you to do it in your own application) |
| Support from DB Engineers | Built-in embedding (ditto) |
| Deploy into your VPC (BYOC) | Open Source |
