You can delete one or more vectors by providing their vector ids, vector id prefix, or metadata filter.

Vectors will be deleted from the default namespace by default. You can use a different namespace by specifying it in the request path.

Request

ids

string[]

Array of vector ids to delete.

prefix

string

Prefix of vector ids to delete.

filter

string

Metadata filter for the vectors to delete.

Deleting vectors with metadata filter is a O(N) operation that performs a full scan. Therefore, it might be slow for large indexes.

namespace

string

default:""

The namespace to use. When no namespace is specified, the default namespace will be used.

deleted

number

The number of the successfully deleted vectors.
