list-vectors

Description

Note

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

List vectors in the specified vector index. 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).

ListVectors operations proceed sequentially; however, for faster performance on a large number of vectors in a vector index, applications can request a parallel ListVectors operation by providing the segmentCount and segmentIndex parameters.

Permissions

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

  • With only s3vectors:ListVectors permission, you can list vector keys when returnData and returnMetadata are both set to false or not specified..
  • If you set returnData or returnMetadata to true, you must have both s3vectors:ListVectors and s3vectors:GetVectors permissions. The request fails with a 403 Forbidden error if you request vector data or metadata without the s3vectors:GetVectors permission.

See also: AWS API Documentation

list-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.

list-vectors is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: vectors

Options

--vector-bucket-name (string)

The name of the vector bucket.

--index-name (string)

The name of the vector index.

--index-arn (string)

The Amazon resource Name (ARN) of the vector index.

--segment-count (integer)

For a parallel ListVectors request, segmentCount represents the total number of vector segments into which the ListVectors operation will be divided. The value of segmentCount corresponds to the number of application workers that will perform the parallel ListVectors operation. For example, if you want to use four application threads to list vectors in a vector index, specify a segmentCount value of 4.

If you specify a segmentCount value of 1, the ListVectors operation will be sequential rather than parallel.

If you specify segmentCount , you must also specify segmentIndex .

--segment-index (integer)

For a parallel ListVectors request, segmentIndex is the index of the segment from which to list vectors in the current request. It identifies an individual segment to be listed by an application worker.

Segment IDs are zero-based, so the first segment is always 0. For example, if you want to use four application threads to list vectors in a vector index, then the first thread specifies a segmentIndex value of 0, the second thread specifies 1, and so on.

The value of segmentIndex must be less than the value provided for segmentCount .

If you provide segmentIndex , you must also provide segmentCount .

--return-data | --no-return-data (boolean)

If true, the vector data of each vector will be included in the response. The default value is false .

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

If true, the metadata associated with each vector will be included 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.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a NextToken is provided in the command’s output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--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

nextToken -> (string)

Pagination token to be used in the subsequent request. The field is empty if no further pagination is required.

vectors -> (list)

Vectors in the current segment.

(structure)

Note

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

The attributes of a vector returned by the ListVectors operation.

key -> (string)

The name of the vector.

data -> (tagged union structure)

The vector data of the vector.

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)

Metadata about the vector.
