AnalyticDBVectorStore

The embeddings generated for the input texts.

Returns a string representing the type of vector store, which subclasses must implement to identify their specific vector storage type.

Adds an array of documents to the collection. The documents are first converted to vectors using the embedDocuments method of the embeddings instance.

Adds an array of vectors and corresponding documents to the collection. The vectors and documents are batch inserted into the database.

Creates a VectorStoreRetriever instance with flexible configuration options.

Creates a new collection in the database. If preDeleteCollection is true, any existing collection with the same name is deleted before the new collection is created.

Creates a new table in the database if it does not already exist. The table is created with columns for id, embedding, document, and metadata. An index is also created on the embedding column if it does not already exist.

Deletes rows from the Cassandra table that match the specified WHERE clause conditions.

Deletes the collection from the database if it exists.

Terminates the connection pool.

Return documents selected using the maximal marginal relevance. Maximal marginal relevance optimizes for similarity to the query AND diversity among selected documents.

Searches for documents similar to a text query by embedding the query and performing a similarity search on the resulting vector.

Performs a similarity search on the vectors in the collection. The search is performed using the given query vector and returns the top k most similar vectors along with their corresponding documents and similarity scores.

Searches for documents similar to a text query by embedding the query, and returns results with similarity scores.

Creates an instance of AnalyticDBVectorStore from an existing index in the database. A new collection is created in the database.

Creates an instance of AnalyticDBVectorStore from an array of texts and corresponding metadata. The texts are first converted to Document instances before being added to the collection.

The name of the serializable. Override to provide an alias or to preserve the serialized module name in minified environments.

Implemented as a static method to support loading logic.
