What it is

Vespa is an open source big data serving engine. Combines vector search, lexical search, ML model evaluation, and ranking in one engine. Built for serving billions of items with millisecond latency.

Why we recommend it

If you need search + recommendations + ML serving in one engine (and at scale), Vespa is the answer. It is what Yahoo uses for its search and ads serving.

When to use it

  • Large-scale search (billions of items)
  • Recommendation systems
  • ML model serving with low latency
  • When you need search + ranking + ML in one
