Instance
Provides an RDS instance resource. A DB instance is an isolated database environment in the cloud. A DB instance can contain multiple user-created databases. Changes to a DB instance can occur when you manually change a parameter, such as allocated_storage, and are reflected in the next maintenance window. Because of this, this provider may report a difference in its planning phase because a modification has not yet taken place. You can use the apply_immediately flag to instruct the service to apply the change immediately (see documentation below). When upgrading the major version of an engine, allow_major_version_upgrade must be set to true.
Note: using
apply_immediatelycan result in a brief downtime as the server reboots. See the AWS Docs on instance-maintenance for more information. Note: All arguments including the username and password will be stored in the raw state as plain-text. Read more about sensitive data instate.
RDS Instance Class Types
Amazon RDS supports three types of instance classes: Standard, Memory Optimized, and Burstable Performance. For more information please read the AWS RDS documentation about DB Instance Class Types
Low-Downtime Updates
By default, RDS applies updates to DB Instances in-place, which can lead to service interruptions. Low-downtime updates minimize service interruptions by performing the updates with an blue-green and switching over the instances when complete. Low-downtime updates are only available for DB Instances using MySQL and MariaDB, as other engines are not supported by RDS Blue/Green deployments. Backups must be enabled to use low-downtime updates. Enable low-downtime updates by setting blue_green_update.enabled to true.

Indicates that major version upgrades are allowed. Changing this parameter does not result in an outage and the change is asynchronously applied as soon as possible.
Specifies whether any database modifications are applied immediately, or during the next maintenance window. Default is false. See [Amazon RDS Documentation for more
Indicates that minor engine upgrades will be applied automatically to the DB instance during the maintenance window. Defaults to true.
The AZ for the RDS instance.
The days to retain backups for. Must be between 0 and 35. Default is 0. Must be greater than 0 if the database is used as a source for a instance-replication, uses low-downtime updates, or will use blue-green.

The engine version to use. If auto_minor_version_upgrade is enabled, you can provide a prefix of the version such as 5.7 (for 5.7.10). The actual engine version used is returned in the attribute engine_version_actual, see Attributes Reference below. For supported values, see the EngineVersion parameter in API action CreateDBInstance. Note that for Amazon Aurora instances the engine version must match the DB cluster's engine version'.
The name of your final DB snapshot when this DB instance is deleted. Must be provided if skip_final_snapshot is set to false. The value must begin with a letter, only contain alphanumeric characters and hyphens, and not end with a hyphen or contain two consecutive hyphens. Must not be provided when deleting a read replica.
Specifies whether mappings of AWS Identity and Access Management (IAM) accounts to database accounts is enabled.
The name of the RDS instance, if omitted, this provider will assign a random, unique identifier. Required if restore_to_point_in_time is specified.
Creates a unique identifier beginning with the specified prefix. Conflicts with identifier.
The instance type of the RDS instance.
The amount of provisioned IOPS. Setting this implies a storage_type of "io1". Can only be set when storage_type is "io1" or "gp3". Cannot be specified for gp3 storage if the allocated_storage value is below a per-engine threshold. See the RDS User Guide for details.
(Optional, but required for some DB engines, i.e., Oracle SE1) License model information for this DB instance.

When configured, the upper limit to which Amazon RDS can automatically scale the storage of the DB instance. Configuring this will automatically ignore differences to allocated_storage. Must be greater than or equal to allocated_storage or 0 to disable Storage Autoscaling.
The interval, in seconds, between points when Enhanced Monitoring metrics are collected for the DB instance. To disable collecting Enhanced Monitoring metrics, specify 0. The default is 0. Valid Values: 0, 1, 5, 10, 15, 30, 60.
The ARN for the IAM role that permits RDS to send enhanced monitoring metrics to CloudWatch Logs. You can find more information on the [AWS
The name of the database to create when the DB instance is created. If this parameter is not specified, no database is created in the DB instance. Note that this does not apply for Oracle or SQL Server engines. See the AWS documentation for more details on what applies for those engines.
