query-objects

Description

Queries the specified pipeline for the names of objects that match the specified set of conditions.

See also: AWS API Documentation

query-objects 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: ids

Options

--pipeline-id (string)

The ID of the pipeline.

--sphere (string)

Indicates whether the query applies to components or instances. The possible values are: COMPONENT , INSTANCE , and ATTEMPT .

--objects-query (structure)

The query that defines the objects to be returned. The Query object can contain a maximum of ten selectors. The conditions in the query are limited to top-level String fields in the object. These filters can be applied to components, instances, and attempts.

selectors -> (list)

List of selectors that define the query. An object must satisfy all of the selectors to match the query.

(structure)

A comparision that is used to determine whether a query should return this object.

fieldName -> (string)

The name of the field that the operator will be applied to. The field name is the "key" portion of the field definition in the pipeline definition syntax that is used by the AWS Data Pipeline API. If the field is not set on the object, the condition fails.

operator -> (structure)

Contains a logical operation for comparing the value of a field with a specified value.

type -> (string)

The logical operation to be performed: equal (EQ ), equal reference (REF_EQ ), less than or equal (LE ), greater than or equal (GE ), or between (BETWEEN ). Equal reference (REF_EQ ) can be used only with reference fields. The other comparison types can be used only with String fields. The comparison types you can use apply only to certain object fields, as detailed below.

The comparison operators EQ and REF_EQ act on the following fields:

  • name
  • @sphere
  • parent
  • @componentParent
  • @instanceParent
  • @status
  • @scheduledStartTime
  • @scheduledEndTime
  • @actualStartTime
  • @actualEndTime

The comparison operators GE , LE , and BETWEEN act on the following fields:

  • @scheduledStartTime
  • @scheduledEndTime
  • @actualStartTime
  • @actualEndTime

Note that fields beginning with the at sign (@) are read-only and set by the web service. When you name fields, you should choose names containing only alpha-numeric values, as symbols may be reserved by AWS Data Pipeline. User-defined fields that you add to a pipeline should prefix their name with the string "my".

values -> (list)

The value that the actual field value will be compared with.

(string)

JSON Syntax:

{
  "selectors": [
    {
      "fieldName": "string",
      "operator": {
        "type": "EQ"|"REF_EQ"|"LE"|"GE"|"BETWEEN",
        "values": ["string", ...]
      }
    }
    ...
  ]
}

--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.

--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

ids -> (list)

The identifiers that match the query selectors.

(string)

marker -> (string)

The starting point for the next page of results. To view the next page of results, call QueryObjects again with this marker value. If the value is null, there are no more results.

hasMoreResults -> (boolean)

Indicates whether there are more results that can be obtained by a subsequent call.
