The Pathway Vector Server is a pipeline written in the Pathway framweork which indexes all files in a given folder, embeds them, and builds a vector index. The pipeline reacts to changes in source files, automatically updating appropriate index entries. The PathwayVectorClient implements the LangChain VectorStore interface and queries the PathwayVectorServer to retrieve up-to-date documents. You can use the client with managed instances of Pathway Vector Store, or run your own instance as described at https://pathway.com/developers/user-guide/llm-xpack/vectorstore_pipeline/ N)AnyCallableIterableListOptionalTuple)Document) Embeddings) VectorStorec eZdZ ddeedeedeefdZ ddededeed eefd Z e Z d efd Z ddeed eed e fd Z y)_VectorStoreClientNhostporturlczd}||s|r t|||_y| t||xsd}d|d||_y)av A client you can use to query :py:class:`VectorStoreServer`.
