How to Choose a Vector Databases Tool
Key criteria to evaluate when comparing Vector Databases solutions:
About LanceDB
LanceDB is an embedded, serverless vector database that runs inside your application process with zero infrastructure. Built on the Lance columnar format, it supports multimodal data (text, images, video), automatic versioning, and scales from local development to cloud deployments.
About Pinecone
Pinecone is the most widely used managed vector database, purpose-built for similarity search and retrieval-augmented generation (RAG). It offers serverless and pod-based architectures, supporting billions of vectors with single-digit millisecond query latency. Pinecone provides metadata filtering, namespaces, and hybrid search combining dense and sparse vectors. Its managed service eliminates infrastructure complexity, making it the go-to choice for teams building semantic search, recommendation engines, and RAG-powered AI applications.
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.
