Pathway Vector Store client.
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/
