Main.Qldb.cancel_journal_kinesis_streamMethod
cancel_journal_kinesis_stream(name, stream_id)
cancel_journal_kinesis_stream(name, stream_id, params::Dict{String,<:Any})

Ends a given Amazon QLDB journal stream. Before a stream can be canceled, its current status must be ACTIVE. You can't restart a stream after you cancel it. Canceled QLDB stream resources are subject to a 7-day retention period, so they are automatically deleted after this limit expires.

Arguments

  • name: The name of the ledger.
  • stream_id: The UUID (represented in Base62-encoded text) of the QLDB journal stream to be canceled.
source
Main.Qldb.create_ledgerMethod
create_ledger(name, permissions_mode)
create_ledger(name, permissions_mode, params::Dict{String,<:Any})

Creates a new ledger in your Amazon Web Services account in the current Region.

Arguments

  • name: 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.
  • permissions_mode: The permissions mode to assign to the ledger that you want to create. This parameter can have one of the following values: ALLOWALL: 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, ALLOWALL) 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. We strongly recommend using the STANDARD permissions mode to maximize the security of your ledger data.

Optional Parameters

Optional parameters can be passed as a params::Dict{String,<:Any}. Valid keys are:

  • "DeletionProtection": 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": 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: AWSOWNEDKMS_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.
  • "Tags": 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.

Main.Qldb.export_journal_to_s3Method
export_journal_to_s3(exclusive_end_time, inclusive_start_time, role_arn, s3_export_configuration, name)
export_journal_to_s3(exclusive_end_time, inclusive_start_time, role_arn, s3_export_configuration, name, params::Dict{String,<:Any})

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. 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.

Arguments

  • exclusive_end_time: The exclusive end date and time for the range of journal contents to export. The ExclusiveEndTime must be in ISO 8601 date and time format and in Universal Coordinated Time (UTC). For example: 2019-06-13T21:36:34Z. The ExclusiveEndTime must be less than or equal to the current UTC date and time.
  • inclusive_start_time: The inclusive start date and time for the range of journal contents to export. The InclusiveStartTime must be in ISO 8601 date and time format and in Universal Coordinated Time (UTC). For example: 2019-06-13T21:36:34Z. The InclusiveStartTime must be before ExclusiveEndTime. If you provide an InclusiveStartTime that is before the ledger's CreationDateTime, Amazon QLDB defaults it to the ledger's CreationDateTime.
  • role_arn: 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 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.
  • s3_export_configuration: The configuration settings of the Amazon S3 bucket destination for your export request.
  • name: The name of the ledger.

Optional Parameters

Optional parameters can be passed as a params::Dict{String,<:Any}. Valid keys are:
