SDK for PHP 3.x

Client: Aws\QLDB\QLDBClient
Service ID: qldb
Version: 2019-01-02

This page describes the parameters and results for the operations of the Amazon QLDB (2019-01-02), and shows how to use the Aws\QLDB\QLDBClient object to call the described operations. This documentation is specific to the 2019-01-02 API version of the service.

Operation Summary

Each of the following operations can be created from a client using $client->getCommand('CommandName'), where "CommandName" is the name of one of the following operations. Note: a command is a value that encapsulates an operation and the parameters used to create an HTTP request.

You can also create and send a command immediately using the magic methods available on a client object: $client->commandName(/* parameters */). You can send the command asynchronously (returning a promise) by appending the word "Async" to the operation name: $client->commandNameAsync(/* parameters */).

Operations

CancelJournalKinesisStream

$result = $client->cancelJournalKinesisStream([/* ... */]);
$promise = $client->cancelJournalKinesisStreamAsync([/* ... */]);

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.

Parameter Syntax

$result = $client->cancelJournalKinesisStream([
    'LedgerName' => '<string>', // REQUIRED
    'StreamId' => '<string>', // REQUIRED
]);

Parameter Details

Members
LedgerName
Required: Yes
Type: string

The name of the ledger.

StreamId
Required: Yes
Type: string

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

Result Syntax

[
    'StreamId' => '<string>',
]

Result Details

Members
StreamId
Type: string

ResourcePreconditionNotMetException:

The operation failed because a condition wasn't satisfied in advance.

CreateLedger

$result = $client->createLedger([/* ... */]);
$promise = $client->createLedgerAsync([/* ... */]);

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

Parameter Syntax

$result = $client->createLedger([
    'DeletionProtection' => true || false,
    'KmsKey' => '<string>',
    'Name' => '<string>', // REQUIRED
    'PermissionsMode' => 'ALLOW_ALL|STANDARD', // REQUIRED
    'Tags' => ['<string>', ...],
]);

Parameter Details

Members
DeletionProtection
Type: 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
Type: 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.

Name
Required: Yes
Type: 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.

PermissionsMode
Required: Yes
Type: 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.

Tags
Type: Associative array of custom strings keys (TagKey) to strings

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.

DeletionProtection
Type: 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.

KmsKeyArn

  • 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:

Parameter Syntax

$result = $client->updateLedgerPermissionsMode([
    'Name' => '<string>', // REQUIRED
    'PermissionsMode' => 'ALLOW_ALL|STANDARD', // REQUIRED
]);

Parameter Details

Members
Name
Required: Yes
Type: string

The name of the ledger.

PermissionsMode
Required: Yes
Type: 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.

LedgerEncryptionDescription

Description

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

For more information, see Encryption at rest in the Amazon QLDB Developer Guide.

Members
EncryptionStatus
Required: Yes
Type: 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.

InaccessibleKmsKeyDateTime
Type: timestamp (string|DateTime or anything parsable by strtotime)

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.

KmsKeyArn
