Delete vectors from a legacy vector index

New projects should use the Documents API. To move an existing index, see Move to the Documents API.

This page shows you how to delete records from a namespace in a legacy vector index with the legacy Vectors API. For a document index, see Delete data.

Delete records by ID

Since Pinecone records can always be efficiently accessed using their ID, deleting by ID is the most efficient way to remove specific records from a namespace.

To remove records from the default namespace, specify "__default__" as the namespace in your request.

# pip install pinecone
from pinecone.grpc import PineconeGRPC as Pinecone

pc = Pinecone(api_key="YOUR_API_KEY")

# To get the unique host for an index, 
# see https://docs.pinecone.io/guides/indexes/target-an-index
index = pc.index(host="INDEX_HOST", grpc=True)

index.delete(ids=["id-1", "id-2"], namespace='example-namespace')

import { Pinecone } from '@pinecone-database/pinecone'

const pc = new Pinecone({ apiKey: "YOUR_API_KEY" })

// To get the unique host for an index, 
// see https://docs.pinecone.io/guides/indexes/target-an-index
const index = pc.index("INDEX_NAME", "INDEX_HOST")

const ns = index.namespace('example-namespace')
// Delete one record by ID.
await ns.deleteOne('id-1');
// Delete more than one record by ID.
await ns.deleteMany(['id-2', 'id-3']);

import io.pinecone.clients.Index;

public class DeleteExample {
    public static void main(String[] args) {
        PineconeConfig config = new PineconeConfig("YOUR_API_KEY");
        // To get the unique host for an index, 
        // see https://docs.pinecone.io/guides/indexes/target-an-index
        config.setHost("INDEX_HOST");
        PineconeConnection connection = new PineconeConnection(config);
        Index index = new Index(config, connection, "INDEX_NAME");
        List<String> ids = Arrays.asList("id-1", "id-2");
        index.deleteByIds(ids, "example-namespace");
    }
}

Delete records by metadata

To delete records from a namespace based on their metadata values, pass a metadata filter expression to the delete operation. This deletes all records in the namespace that match the filter expression. For example, the following code deletes all records with a genre field set to documentary from namespace example-namespace:

# pip install pinecone
from pinecone.grpc import PineconeGRPC as Pinecone

pc = Pinecone(api_key="YOUR_API_KEY")

# To get the unique host for an index, 
# see https://docs.pinecone.io/guides/indexes/target-an-index
index = pc.index(host="INDEX_HOST", grpc=True)

index.delete(
    filter={
        "genre": {"$eq": "documentary"}
    },
    namespace="example-namespace" 
)

import { Pinecone } from '@pinecone-database/pinecone'

const pc = new Pinecone({ apiKey: "YOUR_API_KEY" })

// To get the unique host for an index, 
// see https://docs.pinecone.io/guides/indexes/target-an-index
const index = pc.index("INDEX_NAME", "INDEX_HOST")

const ns = index.namespace('example-namespace')

await ns.deleteMany({
  genre: { $eq: "documentary" },
});

Delete all records in a namespace

To delete all of the records in a namespace but not the namespace itself, provide a namespace parameter and specify the appropriate deleteAll parameter for your SDK. To target the default namespace, set namespace to "__default__".

# pip install pinecone
from pinecone.grpc import PineconeGRPC as Pinecone

pc = Pinecone(api_key="YOUR_API_KEY")

# To get the unique host for an index, 
# see https://docs.pinecone.io/guides/indexes/target-an-index
index = pc.index(host="INDEX_HOST", grpc=True)

index.delete(delete_all=True, namespace='example-namespace')

import { Pinecone } from '@pinecone-database/pinecone'

const pc = new Pinecone({ apiKey: "YOUR_API_KEY" })

// To get the unique host for an index, 
// see https://docs.pinecone.io/guides/indexes/target-an-index
const index = pc.index("INDEX_NAME", "INDEX_HOST")

await index.namespace('example-namespace').deleteAll();

Data freshness

Pinecone is eventually consistent, so there can be a slight delay before new or changed records are visible to queries. You can view index stats to check data freshness.
