Manage data
In addition to inserting and querying data, there are other ways you can interact with vector data in a Pinecone index. This section walks through the various vector operations available.
Create a client instance
If you're using a Pinecone client library to access an index, you'll need to create a client instance:
import pinecone
pinecone.init(api_key="YOUR_API_KEY", environment="YOUR_ENVIRONMENT")
index = pinecone.Index("pinecone-index")
import { Pinecone } from '@pinecone-database/pinecone'
const pinecone = new Pinecone({
apiKey: "YOUR_API_KEY",
environment: "YOUR_ENVIRONMENT"
})
const index = pinecone.index("pinecone-index")
# Not applicable
Specify an index endpoint
Pinecone indexes each have their own DNS endpoint. For cURL and other direct
API calls to a Pinecone index, you'll need to know the dedicated endpoint for
your index.
Index endpoints take the following form:
https://$INDEX_NAME-$PINECONE_PROJECT_ID.svc.$PINECONE_ENVIRONMENT.pinecone.io
$INDEX_NAME
is the name you gave your index when you created it.$PINECONE_PROJECT_ID
is the Pinecone project id that your API key is associated
with. This can be retrieved using thewhoami
operation below.$PINECONE_ENVIRONMENT
is the cloud region for your Pinecone project..
Call whoami
to retrieve your project id.
whoami
to retrieve your project id.The following command retrieves your Pinecone project id.
pinecone.whoami()
PINECONE_ENVIRONMENT='your-environment'
PINECONE_API_KEY='your-api-key'
curl "https://controller.$PINECONE_ENVIRONMENT.pinecone.io/actions/whoami" \
-H "Api-Key: $PINECONE_API_KEY"
Describe index statistics
Get statistics about an index, such as record count per namespace:
index.describe_index_stats()
const indexStats = await index.describeIndexStats();
PINECONE_ENVIRONMENT='your-environment'
PINECONE_API_KEY='your-api-key'
INDEX_NAME='index-name'
PINECONE_PROJECT_ID=$(
curl "https://controller.$PINECONE_ENVIRONMENT.pinecone.io/actions/whoami" \
-H "Api-Key: $PINECONE_API_KEY" | jq -r '.project_name'
)
curl "https://$INDEX_NAME-$PINECONE_PROJECT_ID.svc.$PINECONE_ENVIRONMENT.pinecone.io/describe_index_stats" \
-H "Api-Key: $PINECONE_API_KEY"
Fetching records
The Fetch
operation looks up and returns records, by id, from an index. The returned records include the vector values and/or metadata. Typical fetch latency is under 5ms.
Fetch records by their ids:
index.fetch(["id-1", "id-2"])
# Returns:
# {'namespace': '',
# 'vectors': {'id-1': {'id': 'id-1',
# 'values': [0.568879, 0.632687092, 0.856837332, ...]},
# 'id-2': {'id': 'id-2',
# 'values': [0.00891787093, 0.581895, 0.315718859, ...]}}}
const fetchResult = await index.fetch(['id-1', 'id-2']);
// Returns:
// {'namespace': '',
// 'records': {'id-1': {'id': 'id-1',
// 'values': [0.568879, 0.632687092, 0.856837332, ...]},
// 'id-2': {'id': 'id-2',
// 'values': [0.00891787093, 0.581895, 0.315718859, ...]}}}
PINECONE_ENVIRONMENT='your-environment'
PINECONE_API_KEY='your-api-key'
INDEX_NAME='index-name'
PINECONE_PROJECT_ID=$(
curl "https://controller.$PINECONE_ENVIRONMENT.pinecone.io/actions/whoami" \
-H "Api-Key: $PINECONE_API_KEY" | jq -r '.project_name'
)
curl "https://$INDEX_NAME-$PINECONE_PROJECT_ID.svc.$PINECONE_ENVIRONMENT.pinecone.io/vectors/fetch?ids=id-1&ids=id-2" \
-H "Api-Key: $PINECONE_API_KEY"
# Output:
# {
# "vectors": {
# "id-1": {
# "id": "id-1",
# "values": [0.568879, 0.632687092, 0.856837332, ...]
# },
# "id-2": {
# "id": "id-2",
# "values": [0.00891787093, 0.581895, 0.315718859, ...]
# }
# },
# "namespace": ""
# }
Updating records
There are two methods for updating records and metadata, using full or partial updates.
Full update
Full updates modify the entire record, including vector values and metadata. Updating a record by id is done the same way as inserting records. (Write operations in Pinecone are idempotent.)
The Upsert
operation writes records into an index.
Note
If a new value is upserted for an existing vector id, it will overwrite the
previous value.
- Update the value of the record
("id-3", [3.3, 3.3])
:
index.upsert([("id-3", [3.3, 3.3])])
await index.upsert([
{ id: '3', values: [3.3, 3.3] }
]);
INDEX_NAME='index-name'
PINECONE_ENVIRONMENT='your-environment'
PINECONE_API_KEY='your-api-key'
PINECONE_PROJECT_ID=$(
curl "https://controller.$PINECONE_ENVIRONMENT.pinecone.io/actions/whoami" \
-H "Api-Key: $PINECONE_API_KEY" | jq -r '.project_name'
)
curl -X POST "https://$INDEX_NAME-$PINECONE_PROJECT_ID.svc.$PINECONE_ENVIRONMENT.pinecone.io/vectors/upsert" \
-H "Api-Key: $PINECONE_API_KEY" \
-d '{
"vectors": [
{
"id": "id-3",
"values": [0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8]
}
]
}'
- Fetch the record again. We should get
("id-3", [3.3, 3.3])
:
index.fetch(["id-3"])
await index.fetch(['id-3']);
INDEX_NAME='index-name'
PINECONE_ENVIRONMENT='your-environment'
PINECONE_API_KEY='your-api-key'
PINECONE_PROJECT_ID=$(
curl "https://controller.$PINECONE_ENVIRONMENT.pinecone.io/actions/whoami" \
-H "Api-Key: $PINECONE_API_KEY" | jq -r '.project_name'
)
curl "https://$INDEX_NAME-$PINECONE_PROJECT_ID.svc.$PINECONE_ENVIRONMENT.pinecone.io/vectors/fetch?ids=id-3" \
-H "Api-Key: $PINECONE_API_KEY"
Partial update
The Update
operation performs partial updates that allow changes to part of a record. Given an ID, we can update the vector value with the values
argument or update metadata with the set_metadata
argument.
Warning
The
Update
operation does not validate the existence of ids within an
index. If a non-existent id is given then no changes are made and a200 OK
will be returned.
To update the vector values of record ("id-3", [3.0, 3.0], {"type": "doc", "genre": "drama"})
:
index.update(id="id-3", values=[4.0, 2.0])
await index.update({
id: 'id-3',
values: [4.0, 2.0]
});
INDEX_NAME='index-name'
PINECONE_ENVIRONMENT='your-environment'
PINECONE_API_KEY='your-api-key'
PINECONE_PROJECT_ID=$(
curl "https://controller.$PINECONE_ENVIRONMENT.pinecone.io/actions/whoami" \
-H "Api-Key: $PINECONE_API_KEY" | jq -r '.project_name'
)
curl -X POST "https://$INDEX_NAME-$PINECONE_PROJECT_ID.svc.$PINECONE_ENVIRONMENT.pinecone.io/vectors/update" \
-H "Api-Key: $PINECONE_API_KEY" \
-H 'Content-Type: application/json' \
-d '{
"id": "id-3",
"values": [
4.0,
2.0
]
}'
The updated record would now be ("id-3", [4.0, 2.0], {"type": "doc", "genre": "drama"})
. Values have been updated but the metadata is unchanged.
When updating metadata only specified fields will be modified. If a specified field does not exist, it is added.
Note
Metadata updates apply only to fields passed to the
set_metadata
argument. Any other fields will remain unchanged.
To update the metadata of record ("id-3", [4.0, 2.0], {"type": "doc", "genre": "drama"})
, use code like the following:
index.update(id="id-3", set_metadata={"type": "web", "new": True})
# Update the metadata
await index.update({
id: 'id-3',
metadata: {
type: "web",
new: true,
},
});
# View the updated results
const fetchResults = await index.fetch(['id-3'])
console.log(fetchResults.records['id-3'])
INDEX_NAME='index-name'
PINECONE_ENVIRONMENT='your-environment'
PINECONE_API_KEY='your-api-key'
PINECONE_PROJECT_ID=$(
curl "https://controller.$PINECONE_ENVIRONMENT.pinecone.io/actions/whoami" \
-H "Api-Key: $PINECONE_API_KEY" | jq -r '.project_name'
)
# Update the metadata
curl -X POST "https://$INDEX_NAME-$PINECONE_PROJECT_ID.svc.$PINECONE_ENVIRONMENT.pinecone.io/vectors/update" \
-H "Api-Key: $PINECONE_API_KEY" \
-H 'Content-Type: application/json' \
-d '{
"id": "id-3",
"setMetadata": {
"type": "web",
"new": true
}
}'
# Fetch the record to view the results of the update
curl "https://$INDEX_NAME-$PINECONE_PROJECT_ID.svc.$PINECONE_ENVIRONMENT.pinecone.io/vectors/fetch?ids=id-3" \
-H "Api-Key: $PINECONE_API_KEY"
The updated record would now be ("id-3", [4.0, 2.0], {"type": "web", "genre": "drama", "new": true})
. The type
metadata field has been updated to web
, the new
property has been added with value true
, and the genre
property has been unchanged.
Both vector and metadata can be updated at once by including both values
and metadata arguments. To update both these parts of the "id-3"
record we write:
index.update(id="id-3", values=[1.0, 2.0], set_metadata={"type": "webdoc"})
await index.update({
id: 'id-3',
values: [1.0, 2.0],
metadata: {
type: "webdoc",
},
});
INDEX_NAME='index-name'
PINECONE_ENVIRONMENT='your-environment'
PINECONE_API_KEY='your-api-key'
PINECONE_PROJECT_ID=$(
curl "https://controller.$PINECONE_ENVIRONMENT.pinecone.io/actions/whoami" \
-H "Api-Key: $PINECONE_API_KEY" | jq -r '.project_name'
)
# Update both values and metadata
curl -X POST "https://$INDEX_NAME-$PINECONE_PROJECT_ID.svc.$PINECONE_ENVIRONMENT.pinecone.io/vectors/update" \
-H "Api-Key: $PINECONE_API_KEY" \
-H 'Content-Type: application/json' \
-d '{
"id": "id-3",
"values": [1.0, 2.0],
"setMetadata": {"type": "webdoc"}
}'
# Fetch the record to view the results of the update
curl "https://$INDEX_NAME-$PINECONE_PROJECT_ID.svc.$PINECONE_ENVIRONMENT.pinecone.io/vectors/fetch?ids=id-3" \
-H "Api-Key: $PINECONE_API_KEY"
The updated record would now be ("id-3", [1.0, 2.0], {"type": "webdoc", "genre": "drama", "new": true})
.
Deleting records
The Delete
operation deletes records from an index.
Alternatively, it can also delete all records from an index or namespace.
When deleting large numbers of records, limit the scope of delete operations to hundreds of records per operation.
Instead of deleting all records in an index, delete the index and recreate it.
Delete records by ID
Example
index.delete(ids=["id-1", "id-2"], namespace='example-namespace')
const ns = index.namespace('example-namespace')
// Delete one record by ID.
await ns.deleteOne('id-1');
// Delete more than one record by ID.
await ns.deleteMany(['id-2', 'id-3']);
INDEX_NAME='index-name'
PINECONE_ENVIRONMENT='your-environment'
PINECONE_API_KEY='your-api-key'
PINECONE_PROJECT_ID=$(
curl "https://controller.$PINECONE_ENVIRONMENT.pinecone.io/actions/whoami" \
-H "Api-Key: $PINECONE_API_KEY" | jq -r '.project_name'
)
curl -X POST "https://$INDEX_NAME-$PINECONE_PROJECT_ID.svc.$PINECONE_ENVIRONMENT.pinecone.io/vectors/delete?ids=id-1&ids=id-2&namespace=example-namespace" \
-H "Api-Key: $PINECONE_API_KEY"
Delete records by namespace
To delete all records from a namespace, specify the appropriate parameter for your client and provide a
namespace
parameter.
Note
If you delete all records from a single namespace, it will also delete the
namespace.
Projects on the gcp-starter
environment do not support deleting records by namespace.
Example:
index.delete(delete_all=True, namespace='example-namespace')
await index.namespace('example-namespace').deleteAll();
INDEX_NAME='index-name'
PINECONE_ENVIRONMENT='your-environment'
PINECONE_API_KEY='your-api-key'
PINECONE_PROJECT_ID=$(
curl "https://controller.$PINECONE_ENVIRONMENT.pinecone.io/actions/whoami" \
-H "Api-Key: $PINECONE_API_KEY" | jq -r '.project_name'
)
curl -X POST "https://$INDEX_NAME-$PINECONE_PROJECT_ID.svc.$PINECONE_ENVIRONMENT.pinecone.io/vectors/delete?deleteAll=true&namespace=example-namespace" \
-H "Api-Key: $PINECONE_API_KEY"
Delete records by metadata
To delete records by metadata, pass a metadata filter expression to the delete operation.
