#modify(options = {}) ⇒ Object

Note:

You do not need to set :db_instance_identifier.

Modifies the database instance.

Parameters:

  • options (Hash) (defaults to: {}) —
    • :db_instance_identifier - required - (String) The DB Instance identifier. This value is stored as a lowercase string.
    • :allocated_storage - (Integer) The new storage capacity of the RDS instance. This change does not result in an outage and is applied during the next maintenance window unless the ApplyImmediately parameter is specified as true for this request.
    • :db_instance_class - (String) The new compute and memory capacity of the DB Instance. 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.
    • :db_security_groups - (Array) A list of DB Security Groups to authorize on this DB Instance. This change is asynchronously applied as soon as possible.
    • :vpc_security_group_ids - (Array) 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
    • :apply_immediately - (Boolean) 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.
    • :master_user_password - (String) The new password for the DB Instance master user. This 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.
    • :db_parameter_group_name - (String) The name of the DB Parameter Group to apply to this DB Instance. This change is asynchronously applied as soon as possible for parameters when the ApplyImmediately parameter is specified as true for this request.
    • :backup_retention_period - (Integer) 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.
    • :preferred_backup_window - (String) The daily time range during which automated backups are created if automated backups are enabled, as determined by the BackupRetentionPeriod.
    • :preferred_maintenance_window - (String) The weekly time range (in UTC) during which system maintenance can occur, which may result in an outage. This change is made immediately. If moving this window to the current time, there must be at least 120 minutes between the current time and end of the window to ensure pending changes are applied.
    • :multi_az - (Boolean) Specifies if the DB Instance is a Multi-AZ deployment. Constraints: Cannot be specified if the DB Instance is a read replica.
    • :engine_version - (String) The version number of the database engine to upgrade to. For major version upgrades, if a nondefault 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
    • :allow_major_version_upgrade - (Boolean) Indicates that major version upgrades are allowed. 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.
    • :auto_minor_version_upgrade - (Boolean) Indicates that minor version upgrades will be applied automatically to the DB Instance during the maintenance window.
    • :iops - (Integer) The new provisioned I/O operations per second of the RDS instance. This change does not result in an outage and is applied during the next maintenance window unless the ApplyImmediately parameter is specified as 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
    • :option_group_name - (String) Indicates that the DB Instance should be associated with the specified option group.
    • :new_db_instance_identifier - (String) 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 First character must be a letter Cannot end with a hyphen or contain two consecutive hyphens
