var params = {
  Name: 'STRING_VALUE', /* required */
  PermissionsMode: ALLOW_ALL | STANDARD, /* required */
  DeletionProtection: true || false,
  KmsKey: 'STRING_VALUE',
  Tags: {
    '<TagKey>': 'STRING_VALUE',

qldb.createLedger(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

• params (Object) (defaults to: {}) —
  • Name — (String)

    The name of the ledger that you want to create. The name must be unique among all of the ledgers in your Amazon Web Services account in the current Region.

    Naming constraints for ledger names are defined in Quotas in Amazon QLDB in the Amazon QLDB Developer Guide.

  • Tags — (map<String>)

    The key-value pairs to add as tags to the ledger that you want to create. Tag keys are case sensitive. Tag values are case sensitive and can be null.

  • PermissionsMode — (String)

    The permissions mode to assign to the ledger that you want to create. This parameter can have one of the following values:

    • ALLOW_ALL: A legacy permissions mode that enables access control with API-level granularity for ledgers.

      This mode allows users who have the SendCommand API permission for this ledger to run all PartiQL commands (hence, ALLOW_ALL) on any tables in the specified ledger. This mode disregards any table-level or command-level IAM permissions policies that you create for the ledger.

    • STANDARD: (Recommended) A permissions mode that enables access control with finer granularity for ledgers, tables, and PartiQL commands.

      By default, this mode denies all user requests to run any PartiQL commands on any tables in this ledger. To allow PartiQL commands to run, you must create IAM permissions policies for specific table resources and PartiQL actions, in addition to the SendCommand API permission for the ledger. For information, see Getting started with the standard permissions mode in the Amazon QLDB Developer Guide.

    Note: We strongly recommend using the STANDARD permissions mode to maximize the security of your ledger data.
    Possible values include:
    • "ALLOW_ALL"
    • "STANDARD"
  • DeletionProtection — (Boolean)

    Specifies whether the ledger is protected from being deleted by any user. If not defined during ledger creation, this feature is enabled (true) by default.

    If deletion protection is enabled, you must first disable it before you can delete the ledger. You can disable it by calling the UpdateLedger operation to set this parameter to false.

  • KmsKey — (String)

    The key in Key Management Service (KMS) to use for encryption of data at rest in the ledger. For more information, see Encryption at rest in the Amazon QLDB Developer Guide.

    Use one of the following options to specify this parameter:

    • AWS_OWNED_KMS_KEY: Use an KMS key that is owned and managed by Amazon Web Services on your behalf.

    • Undefined: By default, use an Amazon Web Services owned KMS key.

    • A valid symmetric customer managed KMS key: Use the specified symmetric encryption KMS key in your account that you create, own, and manage.

      Amazon QLDB does not support asymmetric keys. For more information, see Using symmetric and asymmetric keys in the Key Management Service Developer Guide.

    To specify a customer managed KMS key, you can use its key ID, Amazon Resource Name (ARN), alias name, or alias ARN. When using an alias name, prefix it with "alias/". To specify a key in a different Amazon Web Services account, you must use the key ARN or alias ARN.

    For example:

    • Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab

    • Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab

    • Alias name: alias/ExampleAlias

    • Alias ARN: arn:aws:kms:us-east-2:111122223333:alias/ExampleAlias

    For more information, see Key identifiers (KeyId) in the Key Management Service Developer Guide.

  Context (this):

  • (AWS.Response) —

    the response object containing error, data properties, and the original request object.

  Parameters:

  • err (Error) —

    the error object returned from the request. Set to null if the request is successful.

  • data (Object) —

    • PermissionsMode — (String)

      The permissions mode of the ledger.

      Possible values include:
      • "ALLOW_ALL"
      • "STANDARD"
    • DeletionProtection — (Boolean)

      Specifies whether the ledger is protected from being deleted by any user. If not defined during ledger creation, this feature is enabled (true) by default.

      If deletion protection is enabled, you must first disable it before you can delete the ledger. You can disable it by calling the UpdateLedger operation to set this parameter to false.

    • EncryptionDescription — (map)

      Information about the encryption of data at rest in the ledger. This includes the current status, the KMS key, and when the key became inaccessible (in the case of an error). If this parameter is undefined, the ledger uses an Amazon Web Services owned KMS key for encryption.

      • KmsKeyArn — required — (String)

        The Amazon Resource Name (ARN) of the customer managed KMS key that the ledger uses for encryption at rest. If this parameter is undefined, the ledger uses an Amazon Web Services owned KMS key for encryption. It will display AWS_OWNED_KMS_KEY when updating the ledger's encryption configuration to the Amazon Web Services owned KMS key.

      • EncryptionStatus — required — (String)

        The current state of encryption at rest for the ledger. This can be one of the following values:

        • ENABLED: Encryption is fully enabled using the specified key.

        • UPDATING: The ledger is actively processing the specified key change.

          Key changes in QLDB are asynchronous. The ledger is fully accessible without any performance impact while the key change is being processed. The amount of time it takes to update a key varies depending on the ledger size.

        • KMS_KEY_INACCESSIBLE: The specified customer managed KMS key is not accessible, and the ledger is impaired. Either the key was disabled or deleted, or the grants on the key were revoked. When a ledger is impaired, it is not accessible and does not accept any read or write requests.

          An impaired ledger automatically returns to an active state after you restore the grants on the key, or re-enable the key that was disabled. However, deleting a customer managed KMS key is irreversible. After a key is deleted, you can no longer access the ledgers that are protected with that key, and the data becomes unrecoverable permanently.

        Possible values include:
        • "ENABLED"
        • "UPDATING"
        • "KMS_KEY_INACCESSIBLE"
      • InaccessibleKmsKeyDateTime — (Date)

        The date and time, in epoch time format, when the KMS key first became inaccessible, in the case of an error. (Epoch time format is the number of seconds that have elapsed since 12:00:00 AM January 1, 1970 UTC.)

        This parameter is undefined if the KMS key is accessible.

Returns:

• (AWS.Request) —

  a handle to the operation request for subsequent event callback registration.

• params (Object) (defaults to: {}) —
  • LedgerName — (String)

    The name of the ledger.

  • RoleArn — (String)

    The Amazon Resource Name (ARN) of the IAM role that grants QLDB permissions for a journal stream to write data records to a Kinesis Data Streams resource.

    To pass a role to QLDB when requesting a journal stream, you must have permissions to perform the iam:PassRole action on the IAM role resource. This is required for all journal stream requests.

  • Tags — (map<String>)

    The key-value pairs to add as tags to the stream that you want to create. Tag keys are case sensitive. Tag values are case sensitive and can be null.

  • InclusiveStartTime — (Date)

    The inclusive start date and time from which to start streaming journal data. This parameter must be in ISO 8601 date and time format and in Universal Coordinated Time (UTC). For example: 2019-06-13T21:36:34Z.

    The InclusiveStartTime cannot be in the future and must be before ExclusiveEndTime.

    If you provide an InclusiveStartTime that is before the ledger's CreationDateTime, QLDB effectively defaults it to the ledger's CreationDateTime.

  • ExclusiveEndTime — (Date)

    The exclusive date and time that specifies when the stream ends. If you don't define this parameter, the stream runs indefinitely until you cancel it.

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

  • KinesisConfiguration — (map)

    The configuration settings of the Kinesis Data Streams destination for your stream request.

    • StreamArn — required — (String)

      The Amazon Resource Name (ARN) of the Kinesis Data Streams resource.

    • AggregationEnabled — (Boolean)

      Enables QLDB to publish multiple data records in a single Kinesis Data Streams record, increasing the number of records sent per API call.

      Default: True

      Record aggregation has important implications for processing records and requires de-aggregation in your stream consumer. To learn more, see KPL Key Concepts and Consumer De-aggregation in the Amazon Kinesis Data Streams Developer Guide.

  • StreamName — (String)

    The name that you want to assign to the QLDB journal stream. User-defined names can help identify and indicate the purpose of a stream.

    Your stream name must be unique among other active streams for a given ledger. Stream names have the same naming constraints as ledger names, as defined in Quotas in Amazon QLDB in the Amazon QLDB Developer Guide.

Callback (callback):

• function(err, data) { ... }

  Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

  Context (this):

  • (AWS.Response) —

    the response object containing error, data properties, and the original request object.

  Parameters:

  • err (Error) —

    the error object returned from the request. Set to null if the request is successful.

  • data (Object) —

    the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

    • StreamId — (String)

      The UUID (represented in Base62-encoded text) that QLDB assigns to each QLDB journal stream.

Returns:

• (AWS.Request) —

  a handle to the operation request for subsequent event callback registration.

var params = {
  ResourceArn: 'STRING_VALUE', /* required */
  Tags: { /* required */
    '<TagKey>': 'STRING_VALUE',
    /* '<TagKey>': ... */

var params = {
  Name: 'STRING_VALUE', /* required */
  DeletionProtection: true || false,
  KmsKey: 'STRING_VALUE'
};
qldb.updateLedger(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

• params (Object) (defaults to: {}) —
  • Name — (String)

    The name of the ledger.

  • DeletionProtection — (Boolean)

    Specifies whether the ledger is protected from being deleted by any user. If not defined during ledger creation, this feature is enabled (true) by default.

    If deletion protection is enabled, you must first disable it before you can delete the ledger. You can disable it by calling the UpdateLedger operation to set this parameter to false.

  • KmsKey — (String)

    The key in Key Management Service (KMS) to use for encryption of data at rest in the ledger. For more information, see Encryption at rest in the Amazon QLDB Developer Guide.

    Use one of the following options to specify this parameter:

    • AWS_OWNED_KMS_KEY: Use an KMS key that is owned and managed by Amazon Web Services on your behalf.

    • Undefined: Make no changes to the KMS key of the ledger.

    • A valid symmetric customer managed KMS key: Use the specified symmetric encryption KMS key in your account that you create, own, and manage.

      Amazon QLDB does not support asymmetric keys. For more information, see Using symmetric and asymmetric keys in the Key Management Service Developer Guide.

    To specify a customer managed KMS key, you can use its key ID, Amazon Resource Name (ARN), alias name, or alias ARN. When using an alias name, prefix it with "alias/". To specify a key in a different Amazon Web Services account, you must use the key ARN or alias ARN.

    For example:

    • Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab

    • Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab

    • Alias name: alias/ExampleAlias

    • Alias ARN: arn:aws:kms:us-east-2:111122223333:alias/ExampleAlias

    For more information, see Key identifiers (KeyId) in the Key Management Service Developer Guide.

Callback (callback):

• function(err, data) { ... }

  Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

  Context (this):

  • (AWS.Response) —

    the response object containing error, data properties, and the original request object.

  Parameters:

  • err (Error) —

    the error object returned from the request. Set to null if the request is successful.

  • data (Object) —

    the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

    • Name — (String)

      The name of the ledger.

    • Arn — (String)

      The Amazon Resource Name (ARN) for the ledger.

    • State — (String)

      The current status of the ledger.

      Possible values include:
      • "CREATING"
      • "ACTIVE"
      • "DELETING"
      • "DELETED"
    • CreationDateTime — (Date)

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

    • DeletionProtection — (Boolean)

      Specifies whether the ledger is protected from being deleted by any user. If not defined during ledger creation, this feature is enabled (true) by default.

      If deletion protection is enabled, you must first disable it before you can delete the ledger. You can disable it by calling the UpdateLedger operation to set this parameter to false.

    • EncryptionDescription — (map)

      Information about the encryption of data at rest in the ledger. This includes the current status, the KMS key, and when the key became inaccessible (in the case of an error).

      • KmsKeyArn — required — (String)

        The Amazon Resource Name (ARN) of the customer managed KMS key that the ledger uses for encryption at rest. If this parameter is undefined, the ledger uses an Amazon Web Services owned KMS key for encryption. It will display AWS_OWNED_KMS_KEY when updating the ledger's encryption configuration to the Amazon Web Services owned KMS key.

      • EncryptionStatus — required — (String)

        The current state of encryption at rest for the ledger. This can be one of the following values:

        • ENABLED: Encryption is fully enabled using the specified key.

        • UPDATING: The ledger is actively processing the specified key change.

          Key changes in QLDB are asynchronous. The ledger is fully accessible without any performance impact while the key change is being processed. The amount of time it takes to update a key varies depending on the ledger size.

        • KMS_KEY_INACCESSIBLE: The specified customer managed KMS key is not accessible, and the ledger is impaired. Either the key was disabled or deleted, or the grants on the key were revoked. When a ledger is impaired, it is not accessible and does not accept any read or write requests.

          An impaired ledger automatically returns to an active state after you restore the grants on the key, or re-enable the key that was disabled. However, deleting a customer managed KMS key is irreversible. After a key is deleted, you can no longer access the ledgers that are protected with that key, and the data becomes unrecoverable permanently.

        Possible values include:
        • "ENABLED"
        • "UPDATING"
        • "KMS_KEY_INACCESSIBLE"
      • InaccessibleKmsKeyDateTime — (Date)

        The date and time, in epoch time format, when the KMS key first became inaccessible, in the case of an error. (Epoch time format is the number of seconds that have elapsed since 12:00:00 AM January 1, 1970 UTC.)

        This parameter is undefined if the KMS key is accessible.

Returns:

• (AWS.Request) —

  a handle to the operation request for subsequent event callback registration.

var params = {
  Name: 'STRING_VALUE', /* required */
  PermissionsMode: ALLOW_ALL | STANDARD /* required */
};
qldb.updateLedgerPermissionsMode(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

• params (Object) (defaults to: {}) —
  • Name — (String)

    The name of the ledger.

  • PermissionsMode — (String)

    The permissions mode to assign to the ledger. This parameter can have one of the following values:

    • ALLOW_ALL: A legacy permissions mode that enables access control with API-level granularity for ledgers.

      This mode allows users who have the SendCommand API permission for this ledger to run all PartiQL commands (hence, ALLOW_ALL) on any tables in the specified ledger. This mode disregards any table-level or command-level IAM permissions policies that you create for the ledger.

    • STANDARD: (Recommended) A permissions mode that enables access control with finer granularity for ledgers, tables, and PartiQL commands.

      By default, this mode denies all user requests to run any PartiQL commands on any tables in this ledger. To allow PartiQL commands to run, you must create IAM permissions policies for specific table resources and PartiQL actions, in addition to the SendCommand API permission for the ledger. For information, see Getting started with the standard permissions mode in the Amazon QLDB Developer Guide.

    Note: We strongly recommend using the STANDARD permissions mode to maximize the security of your ledger data.
    Possible values include:
    • "ALLOW_ALL"
    • "STANDARD"

Callback (callback):

• function(err, data) { ... }

  Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

  Context (this):

  • (AWS.Response) —

    the response object containing error, data properties, and the original request object.

  Parameters:

  • err (Error) —

    the error object returned from the request. Set to null if the request is successful.

  • data (Object) —

    the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

    • Name — (String)

      The name of the ledger.

    • Arn — (String)

      The Amazon Resource Name (ARN) for the ledger.

    • PermissionsMode — (String)

      The current permissions mode of the ledger.

      Possible values include:
      • "ALLOW_ALL"
      • "STANDARD"

Returns:

• (AWS.Request) —

  a handle to the operation request for subsequent event callback registration.
