Methods

client()

client(): Promise<Pinecone>

Defined in: packages/providers/storage/pinecone/src/PineconeVectorStore.ts:86

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.

Overrides

BaseVectorStore.client

index()

index(): Promise<Index<RecordMetadata>>

Defined in: packages/providers/storage/pinecone/src/PineconeVectorStore.ts:90

Returns

Promise<Index<RecordMetadata>>

clearIndex()

clearIndex(): Promise<void>

Defined in: packages/providers/storage/pinecone/src/PineconeVectorStore.ts:100

Returns

Promise<void>

The result of the delete query.

add()

add(embeddingResults): Promise<string[]>

Defined in: packages/providers/storage/pinecone/src/PineconeVectorStore.ts:111

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.

TODO

Does not create or insert sparse vectors.

Overrides

BaseVectorStore.add

Returns

Promise<void>

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

Overrides
