query-vectors

Description

Note

Amazon S3 Vectors is in preview release for Amazon S3 and is subject to change.

Performs an approximate nearest neighbor search query in a vector index using a query vector. By default, it returns the keys of approximate nearest neighbors. You can optionally include the computed distance (between the query vector and each vector in the response), the vector data, and metadata of each vector in the response.

To specify the vector index, you can either use both the vector bucket name and the vector index name, or use the vector index Amazon Resource Name (ARN).

Permissions

You must have the s3vectors:QueryVectors permission to use this operation. Additional permissions are required based on the request parameters you specify:

  • With only s3vectors:QueryVectors permission, you can retrieve vector keys of approximate nearest neighbors and computed distances between these vectors. This permission is sufficient only when you don’t set any metadata filters and don’t request vector data or metadata (by keeping the returnMetadata parameter set to false or not specified).
  • If you specify a metadata filter or set returnMetadata to true, you must have both s3vectors:QueryVectors and s3vectors:GetVectors permissions. The request fails with a 403 Forbidden error if you request metadata filtering, vector data, or metadata without the s3vectors:GetVectors permission.

See also: AWS API Documentation

query-vectors uses document type values. Document types follow the JSON data model where valid values are: strings, numbers, booleans, null, arrays, and objects. For command input, options and nested parameters that are labeled with the type document must be provided as JSON. Shorthand syntax does not support document types.

Options

--vector-bucket-name (string)

The name of the vector bucket that contains the vector index.

--index-name (string)

The name of the vector index that you want to query.

--index-arn (string)

The ARN of the vector index that you want to query.

--top-k (integer)

The number of results to return for each query.

--query-vector (tagged union structure)

The query vector. Ensure that the query vector has the same dimension as the dimension of the vector index that’s being queried. For example, if your vector index contains vectors with 384 dimensions, your query vector must also have 384 dimensions.

Note

This is a Tagged Union structure. Only one of the following top level keys can be set: float32.

float32 -> (list)

The vector data as 32-bit floating point numbers. The number of elements in this array must exactly match the dimension of the vector index where the operation is being performed.

(float)

Shorthand Syntax:

float32=float,float

JSON Syntax:

{
  "float32": [float, ...]
}

--filter (document)

Metadata filter to apply during the query. For more information about metadata keys, see Metadata filtering in the Amazon S3 User Guide .

JSON Syntax:

{...}

--return-metadata | --no-return-metadata (boolean)

Indicates whether to include metadata in the response. The default value is false .

--return-distance | --no-return-distance (boolean)

Indicates whether to include the computed distance in the response. The default value is false .

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Output

vectors -> (list)

The vectors in the approximate nearest neighbor search.

(structure)

Note

Amazon S3 Vectors is in preview release for Amazon S3 and is subject to change.

The attributes of a vector in the approximate nearest neighbor search.

key -> (string)

The key of the vector in the approximate nearest neighbor search.

data -> (tagged union structure)

The vector data associated with the vector, if requested.

Note

This is a Tagged Union structure. Only one of the following top level keys can be set: float32.

float32 -> (list)

The vector data as 32-bit floating point numbers. The number of elements in this array must exactly match the dimension of the vector index where the operation is being performed.

(float)

metadata -> (document)

The metadata associated with the vector, if requested.

distance -> (float)

The measure of similarity between the vector in the response and the query vector.
