class Aws::QLDB::Types::CreateLedgerRequest

@note When making an API call, you may pass CreateLedgerRequest

data as a hash:

    {
      name: "LedgerName", # required
      tags: {
        "TagKey" => "TagValue",
      },
      permissions_mode: "ALLOW_ALL", # required, accepts ALLOW_ALL, STANDARD
      deletion_protection: false,
      kms_key: "KmsKey",
    }

@!attribute [rw] name

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][1] in the *Amazon QLDB Developer Guide*.

@return [String]

@!attribute [rw] tags

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.
@return [Hash<String,String>]

@!attribute [rw] permissions_mode

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][1] in the
  *Amazon QLDB Developer Guide*.

<note markdown="1"> We strongly recommend using the `STANDARD` permissions mode to
maximize the security of your ledger data.

@return [String]

@!attribute [rw] deletion_protection

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`.
@return [Boolean]

@!attribute [rw] kms_key

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][1] 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][2] 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)][3] in the *Key
Management Service Developer Guide*.
