Exports journal contents within a date and time range from a ledger into a specified Amazon Simple Storage Service (Amazon S3) bucket. A journal export job can write the data objects in either the text or binary representation of Amazon Ion format, or in JSON Lines text format.
In JSON Lines format, each journal block in the exported data object is a valid JSON object that is delimited by a newline. You can use this format to easily integrate JSON exports with analytics tools such as Glue and Amazon Athena because these services can parse newline-delimited JSON automatically. For more information about the format, see JSON Lines .
If the ledger with the given Name
doesn’t exist, then throws ResourceNotFoundException
.
If the ledger with the given Name
is in CREATING
status, then throws ResourcePreconditionNotMetException
.
You can initiate up to two concurrent journal export requests for each ledger. Beyond this limit, journal export requests throw LimitExceededException
.

--name
(string)
The name of the ledger.
--inclusive-start-time
(timestamp)
The inclusive start date and time for the range of journal contents to export.

, Amazon QLDB defaults it to the ledger’sCreationDateTime
.
--exclusive-end-time
(timestamp)
The exclusive end date and time for the range of journal contents to export.
The

must be inISO 8601
date and time format and in Universal Coordinated Time (UTC). For example:2019-06-13T21:36:34Z

--s3-export-configuration
(structure)
The configuration settings of the Amazon S3 bucket destination for your export request.
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) of a symmetric key in Key Management Service (KMS). Amazon S3 does not support asymmetric KMS keys.
You must provide a
KmsKeyArn
if you specifySSE_KMS
as theObjectEncryptionType
.
KmsKeyArn
is not required if you specifySSE_S3
as theObjectEncryptionType
.
Shorthand Syntax:
Bucket=string,Prefix=string,EncryptionConfiguration={ObjectEncryptionType=string,KmsKeyArn=string}
JSON Syntax:
{
"Bucket": "string",
"Prefix": "string",
"EncryptionConfiguration": {
"ObjectEncryptionType": "SSE_KMS"|"SSE_S3"|"NO_ENCRYPTION",
"KmsKeyArn": "string"
}
}
--role-arn
(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 managed key in Key Management Service (KMS) for server-side encryption of your exported data.
To pass a role to QLDB when requesting a journal export, you must have permissions to perform the
iam:PassRole
action on the IAM role resource. This is required for all journal export requests.
--output-format
(string)
The output format of your exported journal data. If this parameter is not specified, the exported data defaults to
ION_TEXT
format.Possible values:
ION_BINARY
ION_TEXT
JSON
--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. 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.
--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
yaml
yaml-stream
--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.
--cli-binary-format
(string)
The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb://
will always be treated as binary and use the file contents directly regardless of the cli-binary-format
setting. When using file://
the file contents will need to properly formatted for the configured cli-binary-format
.
base64
raw-in-base64-out
--no-cli-pager
(boolean)
Disable cli pager for output.
--cli-auto-prompt
(boolean)
Automatically prompt for CLI input parameters.
--no-cli-auto-prompt
(boolean)
Disable automatically prompt for CLI input parameters.
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 export journal blocks to S3
The following export-journal-to-s3
example creates an export job for journal blocks within a specified date and time range from a ledger with the name myExampleLedger
. The export job writes the blocks into a specified Amazon S3 bucket.
aws qldb export-journal-to-s3 \
--name myExampleLedger \
--inclusive-start-time 2019-09-18T00:00:00Z \
--exclusive-end-time 2019-09-18T22:59:59Z \
--role-arn arn:aws:iam::123456789012:role/my-s3-export-role \
--s3-export-configuration file://my-s3-export-config.json
