It provides elastic scaling of compute and storage, making it easier to run document-based applications without manual provisioning. This resource is designed for high availability, security, and integration with other AWS services, while reducing operational overhead. ``` aws.docdbelastic_cluster ``` ## Fields | Title | ID | Type | Data Type | Description | | ---------------------------- | ---- | ------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------- | | _key | core | string | | account_id | core | string | | admin_user_name | core | string | The name of the elastic cluster administrator. | | auth_type | core | string | The authentication type for the elastic cluster. | | backup_retention_period | core | int64 | The number of days for which automatic snapshots are retained. | | cluster_arn | core | string | The ARN identifier of the elastic cluster. | | cluster_endpoint | core | string | The URL used to connect to the elastic cluster. | | cluster_name | core | string | The name of the elastic cluster. | | create_time | core | string | The time when the elastic cluster was created in Universal Coordinated Time (UTC). | | kms_key_id | core | string | The KMS key identifier to use to encrypt the elastic cluster. | | preferred_backup_window | core | string | The daily time range during which automated backups are created if automated backups are enabled, as determined by backupRetentionPeriod. | | preferred_maintenance_window | core | string | The weekly time range during which system maintenance can occur, in Universal Coordinated Time (UTC).
