Methods

add()

add(embeddingResults): Promise<string[]>

Adds vector record(s) to the table.

Parameters

• embeddingResults: BaseNode <Metadata>[]

The Nodes to be inserted, optionally including metadata tuples.

Returns

Promise<string[]>

Due to limitations in the Pinecone client, does not return the upserted ID list, only a Promise resolve/reject.

Implementation of

VectorStoreNoEmbedModel . add

TODO

Does not create or insert sparse vectors.

clearIndex()

clearIndex(): Promise<void>

Delete all records for the current index. NOTE: This operation is not supported by Pinecone for "Starter" (free) indexes.

Returns

Promise<void>

The result of the delete query.

---

client()

client(): Promise<Pinecone>

Connects to the Pinecone account specified in environment vars. This method also checks and creates the named index if not found.

Returns

Promise<Pinecone>

Pinecone client, or the error encountered while connecting/setting up.

---

delete()

delete(refDocId, deleteKwargs?): Promise<void>

Deletes a single record from the database by id. NOTE: Uses the collection property controlled by setCollection/getCollection.

Parameters

• refDocId: string

Unique identifier for the record to delete.

• deleteKwargs?: any

Required by VectorStore interface. Currently ignored.

Returns

Promise<void>

Promise that resolves if the delete query did not throw an error.
