The Supabase Vector Store node is a component used for storing and retrieving vector embeddings using Supabase’s pgvector extension. It allows for upsert operations, similarity search, and MMR (Maximal Marginal Relevance) search on embedded data.
The node includes additional functionality for handling record management, batch upserts, and error handling for null ID values. It’s designed to work seamlessly with Supabase’s vector storage capabilities and integrates well with other LangChain components.
