Request Syntax


PATCH /ledgers/name HTTP/1.1
Content-type: application/json

{
   "DeletionProtection": boolean,
   "KmsKey": "string"
}

URI Request Parameters

The request uses the following URI parameters.

name

The name of the ledger.

Length Constraints: Minimum length of 1. Maximum length of 32.

Pattern: (?!^.*--)(?!^[0-9]+$)(?!^-)(?!.*-$)^[A-Za-z0-9-]+$

Required: Yes

Request Body

The request accepts the following data in JSON format.

DeletionProtection

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.

Type: Boolean

Required: No

KmsKey

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: 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 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.

Type: String

Length Constraints: Maximum length of 1600.

Required: No
