Choose infinity if…

  • infinity is primarily C++; nucliadb is Python.
  • License: infinity is Apache-2.0, nucliadb is Other.
  • Pricing: The software is free and open-source under the Apache-2.0 license, but users may incur costs related to hosting and running Docker containers..
  • Requirements: Min 4 GB RAM; Requires Docker; Requires Docker for deployment, with specific setup instructions for Linux, MacOS, and Windows with WSL2..
  • Tags unique to infinity: ai-native, approximate-nearest-neighbor-search, bm25, cpp20.
  • When you need a database that supports fast hybrid search for dense vector, sparse vector, tensor, and full-text data, specifically tailored for LLM applications.

When NOT to use infinity

  • Avoid using Infinity if your project is constrained by the requirement to use a language other than C++ for database operations, as Infinity is primarily developed in C++.
  • Do not use Infinity if your deployment environment does not support Docker or if you are working in a Windows environment without WSL2, as the setup instructions are specific to Docker and Linux/MacOS
