Manage Data

You are viewing docs for Pinecone v1. Switch to docs Pinecone v2.

Overview

In addition to inserting and querying data, you can also fetch an item ((id, vector) pair) by id, update an item’s vector by id, delete an item by id, or get information about the index.

Information

Get information about an index.

# Connect to index first
index = pinecone.Index("pinecone-index")

index.info()

# InfoResult(index_size=10000)

Get information about a specific namespace within an index.

index.info(namespace='namespace-1')

Fetch

Fetch items by their ids.

index.fetch(ids=["id-1", "id-2"])

# [FetchResult(id='id-1', vector=array([0.99999994, 0.99999994], dtype=float32)),
#  FetchResult(id='id-2', vector=array([1.9999999, 1.9999999], dtype=float32))]

Fetch one item at a time.

index.unary_fetch(id="id-3")

# FetchResult(id='id-3', vector=array([3., 3.], dtype=float32))

Update

Updating an item by id is done the same way as inserting items. (Write operations in Pinecone are idempotent.)

Let’s update the value of the item ("id-3", [3., 3.]):

index.unary_upsert(item=("id-3", 3.3 + np.zeros(2)))

Now fetch the item again and we should get ("id-3", [3.3, 3.3]):

index.unary_fetch(id="id-3")

# FetchResult(id='id-3', vector=array([3.3, 3.3], dtype=float32))

Delete Items

Delete items by their ids.

acks = index.delete(ids=["id-1", "id-2"])
print(acks)

# [DeleteResult(id='id-1'), DeleteResult(id='id-2')]

DeleteResult(id='id-1') is an acknowledgement that the item with id='id-1' has been deleted from the index.

Delete one item at a time.

index.unary_delete(id="id-3")

# DeleteResult(id='id-3')
