When should I avoid vectordb?

Last GitHub push was 224 days ago (slowing maintenance, Nov 29, 2025). Validate activity before betting a new project on vectordb. LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. Data & Retrieval: Skip a heavy ingestion framework when your corpus is small and static; a script plus the embedding API is enough. Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.
