Frequently Asked Questions
Should I start with ChromaDB or Pinecone?
Start with ChromaDB for prototyping — it's free and the fastest to set up. Migrate to Pinecone when you need production scale, SLA, and enterprise features.
Can ChromaDB handle production workloads?
ChromaDB works for small-to-medium production workloads (up to ~10M vectors). For larger scale or enterprise requirements, use Pinecone, Weaviate, or Milvus.
How hard is it to migrate from ChromaDB to Pinecone?
Migration is straightforward — both use similar APIs (add vectors, query by similarity). The main change is switching the vector store client and generating embeddings externally for Pinecone.
