Bases:
CfnResource
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 .

Create a new
AWS::QLDB::Ledger
.- Parameters:
scope (
Construct
) –scope in which this resource is defined.
id (
str
) –scoped id of the resource.
permissions_mode (
str
) – 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 theSendCommand
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 theSendCommand
API permission for the ledger. For information, see Getting started with the standard permissions mode in the Amazon QLDB Developer Guide . .. epigraph:: We strongly recommend using theSTANDARD
permissions mode to maximize the security of your ledger data.deletion_protection (
Union
[bool
,IResolvable
,None
]) – 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 theUpdateLedger
operation to set this parameter tofalse
.kms_key (
Optional
[str
]) – 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 .name (
Optional
[str
]) – The name of the ledger that you want to create. The name must be unique among all of the ledgers in your AWS account in the current Region. Naming constraints for ledger names are defined in Quotas in Amazon QLDB in the Amazon QLDB Developer Guide .tags (
Optional
[Sequence
[Union
[CfnTag
,Dict
[str
,Any
]]]]) – An array of key-value pairs to apply to this resource. For more information, see Tag .
Methods
- add_deletion_override(path)
Syntactic sugar for
addOverride(path, undefined)
.- Parameters:
path (
str
) – The path of the value to delete.- Return type:
None
- add_depends_on(target)
Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.
This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.
- Parameters:
target (
CfnResource
) –- Return type:
None
- add_metadata(key, value)
Add a value to the CloudFormation Resource Metadata.
- Parameters:
key (
str
) –value (
Any
) –
- See:
- Return type:
None
Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.
- add_override(path, value)
Adds an override to the synthesized CloudFormation resource.
To add a property override, either use
addPropertyOverride
or prefixpath
with “Properties.” (i.e.Properties.TopicName
).If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.
To include a literal
.
in the property name, prefix with a\
. In most programming languages you will need to write this as"\\."
because the\
itself will need to be escaped.For example:
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"]) cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")
would add the overrides Example:
"Properties": { "GlobalSecondaryIndexes": [ { "Projection": { "NonKeyAttributes": [ "myattribute" ] ... } ... }, { "ProjectionType": "INCLUDE" ... }, ] ... }
The
value
argument toaddOverride
will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.- Parameters:
path (
str
) –The path of the property, you can use dot notation to override values in complex types. Any intermdediate keys will be created as needed.
value (
Any
) –The value. Could be primitive or complex.
- Return type:
None
- add_property_deletion_override(property_path)
Adds an override that deletes the value of a property from the resource definition.
- Parameters:
property_path (
str
) – The path to the property.- Return type:
None
- add_property_override(property_path, value)
Adds an override to a resource property.
Syntactic sugar for
addOverride("Properties.<...>", value)
.- Parameters:
property_path (
str
) – The path of the property.value (
Any
) – The value.
- Return type:
None
- apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)
Sets the deletion policy of the resource based on the removal policy specified.
The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.
The resource can be deleted (
RemovalPolicy.DESTROY
), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN
).- Parameters:
policy (
Optional
[RemovalPolicy
]) –apply_to_update_replace_policy (
Optional
[bool
]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: truedefault (
Optional
[RemovalPolicy
]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resoure, please consult that specific resource’s documentation.
- Return type:
None
- get_att(attribute_name)
Returns a token for an runtime attribute of this resource.
Ideally, use generated attribute accessors (e.g.
resource.arn
), but this can be used for future compatibility in case there is no generated attribute.- Parameters:
attribute_name (
str
) – The name of the attribute.- Return type:
- get_metadata(key)
Retrieve a value value from the CloudFormation Resource Metadata.
- Parameters:
key (
str
) –- See:
- Return type:
Any
Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.
- inspect(inspector)

- Parameters:
inspector (
TreeInspector
) –tree inspector to collect and process attributes.
- Return type:
None
- override_logical_id(new_logical_id)

new_logical_id (
str
) – The new logical ID to use for this stack element.- Return type:
None

UpdateLedger
operation to set this parameter tofalse
.

{ Ref }
for this element.If, by any chance, the intrinsic reference of a resource is not a string, you could coerce it to an IResolvable through
Lazy.any({ produce: resource.ref })
.
- stack
