Overview

An API client for QLDB. To construct a client, you need to configure a :region and :credentials.

client = Aws::QLDB::Client.new(
  region: region_name,
  credentials: credentials,
  # ...
)

For details on configuring region and credentials see the developer guide.

See #initialize for a full list of supported configuration options.

Parameters:

  • options (Hash)

Options Hash (options):

  • :credentials (required, Aws::CredentialProvider) —

    Your AWS credentials. This can be an instance of any one of the following classes:

    • Aws::Credentials - Used for configuring static, non-refreshing credentials.

    • Aws::SharedCredentials - Used for loading static credentials from a shared file, such as ~/.aws/config.

    • Aws::AssumeRoleCredentials - Used when you need to assume a role.

    • Aws::AssumeRoleWebIdentityCredentials - Used when you need to assume a role after providing credentials via the web.

    • Aws::SSOCredentials - Used for loading credentials from AWS SSO using an access token generated from aws login.

    • Aws::ProcessCredentials - Used for loading credentials from a process that outputs to stdout.

    • Aws::InstanceProfileCredentials - Used for loading credentials from an EC2 IMDS on an EC2 instance.

    • Aws::ECSCredentials - Used for loading credentials from instances running in ECS.

    • Aws::CognitoIdentityCredentials - Used for loading credentials from the Cognito Identity service.

    When :credentials are not configured directly, the following locations will be searched for credentials:

    • Aws.config[:credentials]
    • The :access_key_id, :secret_access_key, and :session_token options.
    • ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY']
    • ~/.aws/credentials
    • ~/.aws/config
    • EC2/ECS IMDS instance profile - When used by default, the timeouts are very aggressive. Construct and pass an instance of Aws::InstanceProfileCredentails or Aws::ECSCredentials to enable retries and extended timeouts. Instance profile credential fetching can be disabled by setting ENV['AWS_EC2_METADATA_DISABLED'] to true.
  • :region (required, String) —

#cancel_journal_kinesis_stream(params = {}) ⇒ Types::CancelJournalKinesisStreamResponse

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.

Examples:

resp = client.cancel_journal_kinesis_stream({
  ledger_name: "LedgerName", # required
  stream_id: "UniqueId", # required
})

Response structure


resp.stream_id #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :ledger_name (required, String) —

    The name of the ledger.

  • :stream_id (required, String) —

    The UUID (represented in Base62-encoded text) of the QLDB journal stream to be canceled.

#create_ledger(params = {}) ⇒ Types::CreateLedgerResponse

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

Examples:

Request syntax with placeholder values


resp = client.create_ledger({
  name: "LedgerName", # required
  tags: {
    "TagKey" => "TagValue",
  },
  permissions_mode: "ALLOW_ALL", # required, accepts ALLOW_ALL, STANDARD
  deletion_protection: false,
  kms_key: "KmsKey",
})

Response structure


resp.name #=> String
resp.arn #=> String
resp.state #=> String, one of "CREATING", "ACTIVE", "DELETING", "DELETED"
resp.creation_date_time #=> Time
resp.permissions_mode #=> String, one of "ALLOW_ALL", "STANDARD"
resp.deletion_protection #=> Boolean
resp.kms_key_arn #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :name (required, 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 (Hash<String,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.

  • :permissions_mode (required, 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.

    We strongly recommend using the STANDARD permissions mode to maximize the security of your ledger data.

  • :deletion_protection (Boolean) —

    The flag that prevents a ledger from being deleted by any user. If not provided on 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 the flag to false.

  • :kms_key (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 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.

#export_journal_to_s3(params = {}) ⇒ Types::ExportJournalToS3Response

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.

Examples:

Request syntax with placeholder values


resp = client.export_journal_to_s3({
  name: "LedgerName", # required
  inclusive_start_time: Time.now, # required
  exclusive_end_time: Time.now, # required

#get_block(params = {}) ⇒ Types::GetBlockResponse

Returns a block object at a specified address in a journal. Also returns a proof of the specified block for verification if DigestTipAddress is provided.

For information about the data contents in a block, see Journal contents in the Amazon QLDB Developer Guide.

If the specified ledger doesn't exist or is in DELETING status, then throws ResourceNotFoundException.

If the specified ledger is in CREATING status, then throws ResourcePreconditionNotMetException.

If no block exists with the specified address, then throws InvalidParameterException.

Examples:

resp.encryption_description.encryption_status #=> String, one of "ENABLED", "UPDATING", "KMS_KEY_INACCESSIBLE"
resp.encryption_description.inaccessible_kms_key_date_time #=> Time

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :name (required, String) —

    The name of the ledger.

  • :deletion_protection (Boolean) —

    The flag that prevents a ledger from being deleted by any user. If not provided on 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 the flag to false.

  • :kms_key (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 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.

#update_ledger_permissions_mode(params = {}) ⇒ Types::UpdateLedgerPermissionsModeResponse

Updates the permissions mode of a ledger.

Before you switch to the STANDARD permissions mode, you must first create all required IAM policies and table tags to avoid disruption to your users. To learn more, see Migrating to the standard permissions mode in the Amazon QLDB Developer Guide.

Examples:

Request syntax with placeholder values


resp = client.update_ledger_permissions_mode({
  name: "LedgerName", # required
  permissions_mode: "ALLOW_ALL", # required, accepts ALLOW_ALL, STANDARD
})

Response structure


resp.name #=> String
resp.arn #=> String
resp.permissions_mode #=> String, one of "ALLOW_ALL", "STANDARD"

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :name (required, String) —

    The name of the ledger.

  • :permissions_mode (required, 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.

    We strongly recommend using the STANDARD permissions mode to maximize the security of your ledger data.
