    Amazon Relational Database Service
    Amazon Relational Database Service (Amazon RDS) is a web service
    that makes it easier to set up, operate, and scale a relational
    database in the cloud. It provides cost-efficient, resizable
    capacity for an industry-standard relational database and manages
    common database administration tasks, freeing up developers to
    focus on what makes their applications and businesses unique.

Amazon RDS gives you access to the capabilities of a familiar
    MySQL or Oracle database server. This means the code,
    applications, and tools you already use today with your existing
    MySQL or Oracle databases work with Amazon RDS without
    modification. Amazon RDS automatically backs up your database and
    maintains the database software that powers your DB instance.
    Amazon RDS is flexible: you can scale your database instance's
    compute resources and storage capacity to meet your application's
    demand. As with all Amazon Web Services, there are no up-front
    investments, and you pay only for the resources you use.

This is the Amazon RDS API Reference . It contains a comprehensive
    description of all Amazon RDS Query APIs and data types. Note that
    this API is asynchronous and some actions may require polling to
    determine when an action has been applied. See the parameter
    description to determine if a change is applied immediately or on
    the next instance reboot or during the maintenance window. For
    more information on Amazon RDS concepts and usage scenarios, go to
    the `Amazon RDS User Guide`_.

If you choose to migrate your DB instance from using standard storage
            to using Provisioned IOPS, or from using Provisioned IOPS to using
            standard storage, the process can take time. The duration of the
            migration depends on several factors such as database load, storage
            size, storage type (standard or Provisioned IOPS), amount of IOPS
            provisioned (if any), and the number of prior scale storage
            operations. Typical migration times are under 24 hours, but the
            process can take up to several days in some cases. During the
            migration, the DB instance will be available for use, but may
            experience performance degradation. While the migration takes
            place, nightly backups for the instance will be suspended. No other
            Amazon RDS operations can take place for the instance, including
            modifying the instance, rebooting the instance, deleting the
            instance, creating a read replica for the instance, and creating a
            DB snapshot of the instance.

:type db_instance_class: string
        :param db_instance_class: The new compute and memory capacity of the DB
            instance. To determine the instance classes that are available for
            a particular DB engine, use the DescribeOrderableDBInstanceOptions
            action.
        Passing a value for this parameter causes an outage during the change
            and is applied during the next maintenance window, unless the
            `ApplyImmediately` parameter is specified as `True` for this
            request.

Default: Uses existing setting

:type db_security_groups: list
        :param db_security_groups:
        A list of DB security groups to authorize on this DB instance. Changing
            this parameter does not result in an outage and the change is
            asynchronously applied as soon as possible.

Constraints:

+ Must be 1 to 255 alphanumeric characters
        + First character must be a letter
        + Cannot end with a hyphen or contain two consecutive hyphens

:type vpc_security_group_ids: list
        :param vpc_security_group_ids:
        A list of EC2 VPC security groups to authorize on this DB instance.
            This change is asynchronously applied as soon as possible.

Constraints:

+ Must be 1 to 255 alphanumeric characters
        + First character must be a letter
        + Cannot end with a hyphen or contain two consecutive hyphens

:type apply_immediately: boolean
        :param apply_immediately: Specifies whether or not the modifications in
            this request and any pending modifications are asynchronously
            applied as soon as possible, regardless of the
            `PreferredMaintenanceWindow` setting for the DB instance.
        If this parameter is passed as `False`, changes to the DB instance are
            applied on the next call to RebootDBInstance, the next maintenance
            reboot, or the next failure reboot, whichever occurs first. See
            each parameter to determine when a change is applied.

Default: `False`

:type master_user_password: string
        :param master_user_password:
        The new password for the DB instance master user. Can be any printable
            ASCII character except "/", '"', or "@".

Changing this parameter does not result in an outage and the change is
            asynchronously applied as soon as possible. Between the time of the
            request and the completion of the request, the `MasterUserPassword`
            element exists in the `PendingModifiedValues` element of the
            operation response.

Default: Uses existing setting

Constraints: Must be 8 to 41 alphanumeric characters (MySQL), 8 to 30
            alphanumeric characters (Oracle), or 8 to 128 alphanumeric
            characters (SQL Server).

Amazon RDS API actions never return the password, so this action
            provides a way to regain access to a master instance user if the
            password is lost.

:type db_parameter_group_name: string
        :param db_parameter_group_name: The name of the DB parameter group to
            apply to this DB instance. Changing this parameter does not result
            in an outage and the change is applied during the next maintenance
            window unless the `ApplyImmediately` parameter is set to `True` for
            this request.
        Default: Uses existing setting

Constraints: The DB parameter group must be in the same DB parameter
            group family as this DB instance.

:type backup_retention_period: integer
        :param backup_retention_period:
        The number of days to retain automated backups. Setting this parameter
            to a positive number enables backups. Setting this parameter to 0
            disables automated backups.

Changing this parameter can result in an outage if you change from 0 to
            a non-zero value or from a non-zero value to 0. These changes are
            applied during the next maintenance window unless the
            `ApplyImmediately` parameter is set to `True` for this request. If
            you change the parameter from one non-zero value to another non-
            zero value, the change is asynchronously applied as soon as
            possible.

Default: Uses existing setting

Constraints:

+ Must be a value from 0 to 8
        + Cannot be set to 0 if the DB instance is a master instance with read
              replicas or if the DB instance is a read replica

:type preferred_backup_window: string
        :param preferred_backup_window:
        The daily time range during which automated backups are created if
            automated backups are enabled, as determined by the
            `BackupRetentionPeriod`. Changing this parameter does not result in
            an outage and the change is asynchronously applied as soon as
            possible.

Constraints:

+ Must be in the format hh24:mi-hh24:mi
        + Times should be Universal Time Coordinated (UTC)
        + Must not conflict with the preferred maintenance window
        + Must be at least 30 minutes

:type preferred_maintenance_window: string
        :param preferred_maintenance_window: The weekly time range (in UTC)
            during which system maintenance can occur, which may result in an
            outage. Changing this parameter does not result in an outage,
            except in the following situation, and the change is asynchronously
            applied as soon as possible. If there are pending actions that
            cause a reboot, and the maintenance window is changed to include
            the current time, then changing this parameter will cause a reboot
            of the DB instance. If moving this window to the current time,
            there must be at least 30 minutes between the current time and end
            of the window to ensure pending changes are applied.
        Default: Uses existing setting

Format: ddd:hh24:mi-ddd:hh24:mi

Valid Days: Mon | Tue | Wed | Thu | Fri | Sat | Sun

Constraints: Must be at least 30 minutes

:type multi_az: boolean
        :param multi_az: Specifies if the DB instance is a Multi-AZ deployment.
            Changing this parameter does not result in an outage and the change
            is applied during the next maintenance window unless the
            `ApplyImmediately` parameter is set to `True` for this request.
        Constraints: Cannot be specified if the DB instance is a read replica.

:type engine_version: string
        :param engine_version: The version number of the database engine to
            upgrade to. Changing this parameter results in an outage and the
            change is applied during the next maintenance window unless the
            `ApplyImmediately` parameter is set to `True` for this request.
        For major version upgrades, if a non-default DB parameter group is
            currently in use, a new DB parameter group in the DB parameter
            group family for the new engine version must be specified. The new
            DB parameter group can be the default for that DB parameter group
            family.

Example: `5.1.42`

:type allow_major_version_upgrade: boolean
        :param allow_major_version_upgrade: 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.
        Constraints: This parameter must be set to true when specifying a value
            for the EngineVersion parameter that is a different major version
            than the DB instance's current version.

:type auto_minor_version_upgrade: boolean
        :param auto_minor_version_upgrade: Indicates that minor version
            upgrades will be applied automatically to the DB instance during
            the maintenance window. Changing this parameter does not result in
            an outage except in the following case and the change is
            asynchronously applied as soon as possible. An outage will result
            if this parameter is set to `True` during the maintenance window,
            and a newer minor version is available, and RDS has enabled auto
            patching for that engine version.

:type iops: integer
        :param iops: The new Provisioned IOPS (I/O operations per second) value
            for the RDS instance. Changing this parameter does not result in an
            outage and the change is applied during the next maintenance window
            unless the `ApplyImmediately` parameter is set to `True` for this
            request.
        Default: Uses existing setting

Constraints: Value supplied must be at least 10% greater than the
            current value. Values that are not at least 10% greater than the
            existing value are rounded up so that they are 10% greater than the
            current value.

Type: Integer

If you choose to migrate your DB instance from using standard storage
            to using Provisioned IOPS, or from using Provisioned IOPS to using
            standard storage, the process can take time. The duration of the
            migration depends on several factors such as database load, storage
            size, storage type (standard or Provisioned IOPS), amount of IOPS
            provisioned (if any), and the number of prior scale storage
            operations. Typical migration times are under 24 hours, but the
            process can take up to several days in some cases. During the
            migration, the DB instance will be available for use, but may
            experience performance degradation. While the migration takes
            place, nightly backups for the instance will be suspended. No other
            Amazon RDS operations can take place for the instance, including
            modifying the instance, rebooting the instance, deleting the
            instance, creating a read replica for the instance, and creating a
            DB snapshot of the instance.

:type option_group_name: string
        :param option_group_name: Indicates that the DB instance should be
            associated with the specified option group. Changing this parameter
            does not result in an outage except in the following case and the
            change is applied during the next maintenance window unless the
            `ApplyImmediately` parameter is set to `True` for this request. If
            the parameter change results in an option group that enables OEM,
            this change can cause a brief (sub-second) period during which new
            connections are rejected but existing connections are not
            interrupted.
        Permanent options, such as the TDE option for Oracle Advanced Security
            TDE, cannot be removed from an option group, and that option group
            cannot be removed from a DB instance once it is associated with a
            DB instance

:type new_db_instance_identifier: string
        :param new_db_instance_identifier:
        The new DB instance identifier for the DB instance when renaming a DB
            Instance. This value is stored as a lowercase string.

Constraints:

+ Must contain from 1 to 63 alphanumeric characters or hyphens

        Rebooting a DB instance restarts the database engine service.
        A reboot also applies to the DB instance any modifications to
        the associated DB parameter group that were pending. Rebooting
        a DB instance results in a momentary outage of the instance,
        during which the DB instance status is set to rebooting. If
        the RDS instance is configured for MultiAZ, it is possible
        that the reboot will be conducted through a failover. An

        availability of your DB instance deployment or to restore
        operations to the original AZ after a failover occurs.

The time required to reboot is a function of the specific
        database engine's crash recovery process. To improve the

        Restores a DB instance to an arbitrary point-in-time. Users
        can restore to any point in time before the
        latestRestorableTime for up to backupRetentionPeriod days. The
        target database is created from the source database with the
        same configuration as the original database except that the DB
        instance is created with the default DB security group.

:type source_db_instance_identifier: string
        :param source_db_instance_identifier:
        The identifier of the source DB instance from which to restore.

Constraints:

+ Must be the identifier of an existing database instance
        + Must contain from 1 to 63 alphanumeric characters or hyphens
        + First character must be a letter
        + Cannot end with a hyphen or contain two consecutive hyphens

:type target_db_instance_identifier: string
        :param target_db_instance_identifier:
        The name of the new database instance to be created.

Constraints:

+ Must contain from 1 to 63 alphanumeric characters or hyphens
        + First character must be a letter
        + Cannot end with a hyphen or contain two consecutive hyphens

:type restore_time: timestamp
        :param restore_time: The date and time to restore from.
        Valid Values: Value must be a UTC time

Constraints:

+ Must be before the latest restorable time for the DB instance
        + Cannot be specified if UseLatestRestorableTime parameter is true

Example: `2009-09-07T23:45:00Z`

:type use_latest_restorable_time: boolean
        :param use_latest_restorable_time: Specifies whether ( `True`) or not (
            `False`) the DB instance is restored from the latest backup time.
        Default: `False`

Constraints: Cannot be specified if RestoreTime parameter is provided.

Default: The same DBInstanceClass as the original DB instance.

:type port: integer
        :param port: The port number on which the database accepts connections.
        Constraints: Value must be `1150-65535`

Default: The same port as the original DB instance.

:type availability_zone: string
        :param availability_zone: The EC2 Availability Zone that the database
            instance will be created in.
        Default: A random, system-chosen Availability Zone.

Constraint: You cannot specify the AvailabilityZone parameter if the
            MultiAZ parameter is set to true.

Example: `us-east-1a`

:type db_subnet_group_name: string
        :param db_subnet_group_name: The DB subnet group name to use for the
            new instance.

:type multi_az: boolean
        :param multi_az: Specifies if the DB instance is a Multi-AZ deployment.
        Constraint: You cannot specify the AvailabilityZone parameter if the
            MultiAZ parameter is set to `True`.

:type publicly_accessible: boolean
        :param publicly_accessible: Specifies the accessibility options for the
            DB instance. A value of true specifies an Internet-facing instance
            with a publicly resolvable DNS name, which resolves to a public IP
            address. A value of false specifies an internal instance with a DNS
            name that resolves to a private IP address.
        Default: The default behavior varies depending on whether a VPC has
            been requested or not. The following list shows the default
            behavior in each case.

+ **Default VPC:**true
        + **VPC:**false

If no DB subnet group has been specified as part of the request and the
            PubliclyAccessible value has not been set, the DB instance will be
            publicly accessible. If a specific DB subnet group has been
            specified as part of the request and the PubliclyAccessible value
            has not been set, the DB instance will be private.

:type auto_minor_version_upgrade: boolean
        :param auto_minor_version_upgrade: Indicates that minor version
            upgrades will be applied automatically to the DB instance during
            the maintenance window.

:type license_model: string
        :param license_model: License model information for the restored DB
            instance.
        Default: Same as source.

Valid values: `license-included` | `bring-your-own-license` | `general-
            public-license`

        :param db_name:
        The database name for the restored DB instance.

This parameter is not used for the MySQL engine.

:type engine: string
        :param engine: The database engine to use for the new instance.
        Default: The same as source

Constraint: Must be compatible with the engine of the source

Example: `oracle-ee`

:type iops: integer
        :param iops: The amount of Provisioned IOPS (input/output operations
            per second) to be initially allocated for the DB instance.
        Constraints: Must be an integer greater than 1000.

:type option_group_name: string
        :param option_group_name: The name of the option group to be used for
            the restored DB instance.
        Permanent options, such as the TDE option for Oracle Advanced Security
            TDE, cannot be removed from an option group, and that option group
            cannot be removed from a DB instance once it is associated with a
            DB instance

:type tags: list
        :param tags: A list of tags. Tags must be passed as tuples in the form
            [('key1', 'valueForKey1'), ('key2', 'valueForKey2')]
