Create a CassandraGraphVectorStore from a document list.
Cassandra key space. If not provided, it is resolved from cassio.
Cassandra table (required).
Optional list of IDs associated with the documents.
Optional time-to-live for the added documents.
Optional options used to create the body index. Eg. body_index_options = [cassio.table.cql.STANDARD_ANALYZER]
Optional list of metadata keys to not index.
i.e. to fine-tune which of the metadata fields are indexed.
Note: if you plan to have massive unique text metadata entries,
consider not indexing them for performance
(and to overcome max-length limitations).
Note: the metadata_indexing parameter from
langchain_community.utilities.cassandra.Cassandra is not
exposed since CassandraGraphVectorStore only supports the
deny_list option.
