AWS CLI Command Reference

[ aws . qldb ]

list-journal-s3-exports-for-ledger

Description

Returns an array of journal export job descriptions for a specified ledger.

This action returns a maximum of MaxResults items, and is paginated so that you can retrieve all the items by calling ListJournalS3ExportsForLedger multiple times.

This action does not return any expired export jobs. For more information, see Export Job Expiration in the Amazon QLDB Developer Guide .

See ‘aws help’ for descriptions of global parameters.

Synopsis

  list-journal-s3-exports-for-ledger
--name <value>
[--max-results <value>]
[--next-token <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]

Options

--name (string)

The name of the ledger.

--max-results (integer)

The maximum number of results to return in a single ListJournalS3ExportsForLedger request. (The actual number of results returned might be fewer.)

--next-token (string)

A pagination token, indicating that you want to retrieve the next page of results. If you received a value for NextToken in the response from a previous ListJournalS3ExportsForLedger call, then you should use that value as input here.

--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.

--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.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

Examples

To list journal export jobs for a ledger

The following list-journal-s3-exports-for-ledger example lists journal export jobs for the specified ledger.

aws qldb list-journal-s3-exports-for-ledger \
    --name myExampleLedger

Output:

{
    "JournalS3Exports": [
        {
            "LedgerName": "myExampleLedger",
            "ExclusiveEndTime": 1568847599.0,

Output

JournalS3Exports -> (list)

The array of journal export job descriptions that are associated with the specified ledger.

(structure)

The information about a journal export job, including the ledger name, export ID, when it was created, current status, and its start and end time export parameters.

LedgerName -> (string)

The name of the ledger.

ExportId -> (string)

The unique ID of the journal export job.

ExportCreationTime -> (timestamp)

The date and time, in epoch time format, when the export job was created. (Epoch time format is the number of seconds elapsed since 12:00:00 AM January 1, 1970 UTC.)

Status -> (string)

The current state of the journal export job.

InclusiveStartTime -> (timestamp)

The inclusive start date and time for the range of journal contents that are specified in the original export request.

ExclusiveEndTime -> (timestamp)

The exclusive end date and time for the range of journal contents that are specified in the original export request.

S3ExportConfiguration -> (structure)

The Amazon Simple Storage Service (Amazon S3) bucket location in which a journal export job writes the journal contents.

Bucket -> (string)

The Amazon S3 bucket name in which a journal export job writes the journal contents.

The bucket name must comply with the Amazon S3 bucket naming conventions. For more information, see Bucket Restrictions and Limitations in the Amazon S3 Developer Guide .

Prefix -> (string)

The prefix for the Amazon S3 bucket in which a journal export job writes the journal contents.

The prefix must comply with Amazon S3 key naming rules and restrictions. For more information, see Object Key and Metadata in the Amazon S3 Developer Guide .

The following are examples of valid Prefix values:

  • JournalExports-ForMyLedger/Testing/

  • JournalExports

  • My:Tests/

EncryptionConfiguration -> (structure)

The encryption settings that are used by a journal export job to write data in an Amazon S3 bucket.

ObjectEncryptionType -> (string)

The Amazon S3 object encryption type.

To learn more about server-side encryption options in Amazon S3, see Protecting Data Using Server-Side Encryption in the Amazon S3 Developer Guide .

KmsKeyArn -> (string)

The Amazon Resource Name (ARN) for a symmetric customer master key (CMK) in AWS Key Management Service (AWS KMS). Amazon QLDB does not support asymmetric CMKs.

You must provide a KmsKeyArn if you specify SSE_KMS as the ObjectEncryptionType .

KmsKeyArn is not required if you specify SSE_S3 as the ObjectEncryptionType .

RoleArn -> (string)

The Amazon Resource Name (ARN) of the IAM role that grants QLDB permissions for a journal export job to do the following:

  • Write objects into your Amazon Simple Storage Service (Amazon S3) bucket.

  • (Optional) Use your customer master key (CMK) in AWS Key Management Service (AWS KMS) for server-side encryption of your exported data.

NextToken -> (string)

  • If NextToken is empty, then the last page of results has been processed and there are no more results to be retrieved.

  • If NextToken is not empty, then there are more results available. To retrieve the next page of results, use the value of NextToken in a subsequent ListJournalS3ExportsForLedger call.
