public class CfnLedger
extends CfnResource
implements IInspectable

A CloudFormation `AWS::QLDB::Ledger`.

The AWS::QLDB::Ledger resource specifies a new Amazon Quantum Ledger Database (Amazon QLDB) ledger in your AWS account . Amazon QLDB is a fully managed ledger database that provides a transparent, immutable, and cryptographically verifiable transaction log owned by a central trusted authority. You can use QLDB to track all application data changes, and maintain a complete and verifiable history of changes over time.

For more information, see CreateLedger in the Amazon QLDB API Reference .

Example:

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.qldb.*;
 CfnLedger cfnLedger = CfnLedger.Builder.create(this, "MyCfnLedger")
         .permissionsMode("permissionsMode")
         // the properties below are optional

Field Detail

CFN_RESOURCE_TYPE_NAME

public static final java.lang.String CFN_RESOURCE_TYPE_NAME

The CloudFormation resource type name for this resource class.

Constructor Detail

CfnLedger

protected CfnLedger(software.amazon.jsii.JsiiObjectRef objRef)

CfnLedger

protected CfnLedger(software.amazon.jsii.JsiiObject.InitializationMode initializationMode)

CfnLedger

public CfnLedger(Construct scope,
                 java.lang.String id,
                 CfnLedgerProps props)

Create a new `AWS::QLDB::Ledger`.

Parameters:

scope - - scope in which this resource is defined. This parameter is required.

id - - scoped id of the resource. This parameter is required.

props - - resource properties. This parameter is required.

Method Detail

inspect

public void inspect(TreeInspector inspector)

Examines the CloudFormation resource and discloses attributes.

Specified by:

inspect in interface IInspectable

Parameters:

inspector - - tree inspector to collect and process attributes. This parameter is required.

renderProperties

protected java.util.Map<java.lang.String,java.lang.Object> renderProperties(java.util.Map<java.lang.String,java.lang.Object> props)

Overrides:

renderProperties in class CfnResource

Parameters:

props - This parameter is required.

getCfnProperties

protected java.util.Map<java.lang.String,java.lang.Object> getCfnProperties()

Overrides:

getCfnProperties in class CfnResource

getTags

public TagManager getTags()

An array of key-value pairs to apply to this resource.

For more information, see Tag .

getPermissionsMode

public java.lang.String getPermissionsMode()

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.

setPermissionsMode

public void setPermissionsMode(java.lang.String value)

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.

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.

getDeletionProtection

public java.lang.Object getDeletionProtection()

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 the parameter to false .

setDeletionProtection

public void setDeletionProtection(java.lang.Boolean value)

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 the parameter to false .

setDeletionProtection

public void setDeletionProtection(IResolvable value)

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 the parameter to false .

getKmsKey

public java.lang.String getKmsKey()

The key in AWS Key Management Service ( AWS 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 AWS KMS key that is owned and managed by AWS on your behalf.
• Undefined : By default, use an AWS 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 AWS 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 AWS 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 AWS Key Management Service Developer Guide .

setKmsKey

public void setKmsKey(java.lang.String value)

The key in AWS Key Management Service ( AWS 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 AWS KMS key that is owned and managed by AWS on your behalf.
• Undefined : By default, use an AWS owned KMS key.
