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.

#initialize(options) ⇒ Client

Returns a new instance of Client.

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

Instance Method Details

#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:

Request syntax with placeholder values


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 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 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 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.

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 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

#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.
