How to Choose a Vector Databases Tool
Key criteria to evaluate when comparing Vector Databases solutions:
About ArangoDB
ArangoDB is a multi-model database supporting graph, document, and search in a single engine.
About MongoDB Atlas Vector Search
MongoDB Atlas Vector Search adds vector similarity search directly into MongoDB, allowing developers to combine vector embeddings with traditional document queries, full-text search, and geospatial queries in a single database. It eliminates the need for a separate vector database for teams already using MongoDB.
What is Vector Databases?
Purpose-built databases for storing, indexing, and querying high-dimensional vector embeddings used in semantic search, RAG, and recommendation systems.

What is a vector database?▾
A vector database stores high-dimensional numerical representations (embeddings) of data like text, images, or audio, and enables fast similarity search across millions or billions of vectors using approximate nearest neighbor algorithms.
Do I need a dedicated vector database or can I use pgvector?▾
For small to medium datasets (under 10 million vectors), pgvector in PostgreSQL works well and avoids adding another service. For larger datasets or when you need advanced features like hybrid search and real-time indexing, a dedicated vector database is recommended.
How do I choose the right embedding model for my vector database?▾
Match the embedding model to your use case. For general text search, models like OpenAI text-embedding-3 or Cohere embed-v3 work well. For domain-specific applications, consider fine-tuned models. Always benchmark with your actual data.
