| _key | core | string | |
| account_id | core | string | |
| allocated_storage | core | int64 | The amount of storage (in gigabytes) that is allocated for the replication instance. |
| auto_minor_version_upgrade | core | bool | Boolean value indicating if minor version upgrades will be automatically applied to the instance. |
| availability_zone | core | string | The Availability Zone for the instance. |
| dns_name_servers | core | string | The DNS name servers supported for the replication instance to access your on-premise source or target database. |
| engine_version | core | string | The engine version number of the replication instance. If an engine version number is not specified when a replication instance is created, the default is the latest engine version available. When modifying a major engine version of an instance, also set AllowMajorVersionUpgrade to true. |
| free_until | core | timestamp | The expiration date of the free replication instance that is part of the Free DMS program. |
| instance_create_time | core | timestamp | The time the replication instance was created. |
| kms_key_id | core | string | An KMS key identifier that is used to encrypt the data on the replication instance. If you don't specify a value for the KmsKeyId parameter, then DMS uses your default encryption key. KMS creates the default encryption key for your Amazon Web Services account. Your Amazon Web Services account has a different default encryption key for each Amazon Web Services Region. |
| multi_az | core | bool | Specifies whether the replication instance is a Multi-AZ deployment. You can't set the AvailabilityZone parameter if the Multi-AZ parameter is set to true. |
| network_type | core | string | The type of IP address protocol used by a replication instance, such as IPv4 only or Dual-stack that supports both IPv4 and IPv6 addressing. IPv6 only is not yet supported. |
| pending_modified_values | core | json | The pending modification values. |
| preferred_maintenance_window | core | string | The maintenance window times for the replication instance. Any pending upgrades to the replication instance are performed during this time. |
| publicly_accessible | core | bool | Specifies the accessibility options for the replication instance. A value of true represents an instance with a public IP address. A value of false represents an instance with a private IP address. The default value is true. |
| replication_instance_arn | core | string | The Amazon Resource Name (ARN) of the replication instance. |
| replication_instance_class | core | string | The compute and memory capacity of the replication instance as defined for the specified replication instance class. It is a required parameter, although a default value is pre-selected in the DMS console. For more information on the settings and capacities for the available replication instance classes, see Selecting the right DMS replication instance for your migration. |
| replication_instance_identifier | core | string | The replication instance identifier is a required parameter. This parameter is stored as a lowercase string. Constraints: Must contain 1-63 alphanumeric characters or hyphens. First character must be a letter. Cannot end with a hyphen or contain two consecutive hyphens. Example: myrepinstance |
| replication_instance_ipv6_addresses | core | array<string> | One or more IPv6 addresses for the replication instance. |
| replication_instance_private_ip_address | core | string | The private IP address of the replication instance. |
| replication_instance_private_ip_addresses | core | array<string> | One or more private IP addresses for the replication instance. |
| replication_instance_public_ip_address | core | string | The public IP address of the replication instance. |
| replication_instance_public_ip_addresses | core | array<string> | One or more public IP addresses for the replication instance. |
| replication_instance_status | core | string | The status of the replication instance. The possible return values include: "available" "creating" "deleted" "deleting" "failed" "modifying" "upgrading" "rebooting" "resetting-master-credentials" "storage-full" "incompatible-credentials" "incompatible-network" "maintenance" |
| replication_subnet_group | core | json | The subnet group for the replication instance. |
| secondary_availability_zone | core | string | The Availability Zone of the standby replication instance in a Multi-AZ deployment. |
| tags | core | hstore | |
| vpc_security_groups | core | json | The VPC security group for the instance. |
