list-datastores

Description

Retrieves a list of data stores.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

list-datastores 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: datastoreSummaries

Synopsis

  list-datastores
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those 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. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To retrieve a list of data stores

The following list-datastores example displays summary information about the available data stores.

aws iotanalytics list-datastores

Output:

{
    "datastoreSummaries": [
        {
            "status": "ACTIVE",
            "datastoreName": "mydatastore",
            "creationTime": 1557858971.02,
            "lastUpdateTime": 1557858971.02
        }
    ]
}

For more information, see ListDatastores in the AWS IoT Analytics API Reference.

Output

datastoreSummaries -> (list)

A list of DatastoreSummary objects.

(structure)

A summary of information about a data store.

datastoreName -> (string)

The name of the data store.

datastoreStorage -> (structure)

Where data in a data store is stored.

serviceManagedS3 -> (structure)

Used to store data in an Amazon S3 bucket managed by IoT Analytics.

customerManagedS3 -> (structure)

Used to store data in an Amazon S3 bucket managed by IoT Analytics.

bucket -> (string)

The name of the Amazon S3 bucket where your data is stored.

keyPrefix -> (string)

(Optional) The prefix used to create the keys of the data store data objects. Each object in an Amazon S3 bucket has a key that is its unique identifier in the bucket. Each object in a bucket has exactly one key. The prefix must end with a forward slash (/).

roleArn -> (string)

The ARN of the role that grants IoT Analytics permission to interact with your Amazon S3 resources.

iotSiteWiseMultiLayerStorage -> (structure)

Used to store data used by IoT SiteWise in an Amazon S3 bucket that you manage.

customerManagedS3Storage -> (structure)

Used to store data used by IoT SiteWise in an Amazon S3 bucket that you manage.

bucket -> (string)

The name of the Amazon S3 bucket where your data is stored.

keyPrefix -> (string)

(Optional) The prefix used to create the keys of the data store data objects. Each object in an Amazon S3 bucket has a key that is its unique identifier in the bucket. Each object in a bucket has exactly one key. The prefix must end with a forward slash (/).

status -> (string)

The status of the data store.

creationTime -> (timestamp)

When the data store was created.

lastUpdateTime -> (timestamp)

The last time the data store was updated.

lastMessageArrivalTime -> (timestamp)

The last time when a new message arrived in the data store.

IoT Analytics updates this value at most once per minute for Amazon Simple Storage Service one data store. Hence, the lastMessageArrivalTime value is an approximation.

This feature only applies to messages that arrived in the data store after October 23, 2020.

fileFormatType -> (string)

The file format of the data in the data store.

datastorePartitions -> (structure)

Contains information about the partition dimensions in a data store.

partitions -> (list)

A list of partition dimensions in a data store.

(structure)

A single dimension to partition a data store. The dimension must be an AttributePartition or a TimestampPartition .

attributePartition -> (structure)

A partition dimension defined by an attributeName .

attributeName -> (string)

The name of the attribute that defines a partition dimension.

timestampPartition -> (structure)

A partition dimension defined by a timestamp attribute.

attributeName -> (string)

The attribute name of the partition defined by a timestamp.

timestampFormat -> (string)

The timestamp format of a partition defined by a timestamp. The default format is seconds since epoch (January 1, 1970 at midnight UTC time).

nextToken -> (string)

The token to retrieve the next set of results, or null if there are no more results.
