To use, you should have the `rockset` python package installed. Note that to use this, the collection being used must already exist in your Rockset instance. You must also ensure you use a Rockset ingest transformation to apply `VECTOR_ENFORCE` on the column being used to store `embedding_key` in the collection. See: https://rockset.com/blog/introducing-vector-search-on-rockset/ for more details Everything below assumes `commons` Rockset workspace. Example: .. code-block:: python from langchain_community.vectorstores import Rockset from langchain_community.embeddings.openai import OpenAIEmbeddings import rockset # Make sure you use the right host (region) for your Rockset instance # and APIKEY has both read-write access to your collection. rs = rockset.RocksetClient(host=rockset.Regions.use1a1, api_key="***") collection_name = "langchain_demo" embeddings = OpenAIEmbeddings() vectorstore = Rockset(rs, collection_name, embeddings, "description", "description_embedding") commonsclientr embeddingsr collection_namestrtext_key embedding_key workspacecZ ddlm}n#t$rtdwxYwt||st dt |||_||_||_||_ ||_ ||_ |j ddS#t$rYdSwxYw)aNInitialize with Rockset client.
