Examples:

Request syntax with placeholder values


dbparametergroup = db_parameter_group.create({
  db_parameter_group_family: "String", # required
  description: "String", # required
  tags: [
    {
      key: "String",

Parameters:

  • options (Hash) (defaults to: {}) —

    ({})

Options Hash (options):

  • :db_parameter_group_family (required, String) —

    The DB parameter group family name. A DB parameter group can be associated with one and only one DB parameter group family, and can be applied only to a DB instance running a database engine and engine version compatible with that DB parameter group family.

    To list all of the available parameter group families for a DB engine, use the following command:

    aws rds describe-db-engine-versions --query "DBEngineVersions[].DBParameterGroupFamily" --engine <engine>

    For example, to list all of the available parameter group families for the MySQL DB engine, use the following command:

    aws rds describe-db-engine-versions --query "DBEngineVersions[].DBParameterGroupFamily" --engine mysql

    The output contains duplicates.

    The following are the valid DB engine values:

    • aurora-mysql

#modify(options = {}) ⇒ DBParameterGroup

Examples:

Request syntax with placeholder values


dbparametergroup = db_parameter_group.modify({
  parameters: [ # required
    {
      parameter_name: "String",
      parameter_value: "PotentiallySensitiveParameterValue",
      description: "String",
      source: "String",
      apply_type: "String",
      data_type: "String",
      allowed_values: "String",
      is_modifiable: false,
      minimum_engine_version: "String",
      apply_method: "immediate", # accepts immediate, pending-reboot
      supported_engine_modes: ["String"],
    },
  ],
})

Parameters:

  • options (Hash) (defaults to: {}) —

    ({})

Options Hash (options):

  • :parameters (required, Array<Types::Parameter>) —

    An array of parameter names, values, and the application methods for the parameter update. At least one parameter name, value, and application method must be supplied; later arguments are optional. A maximum of 20 parameters can be modified in a single request.

    Valid Values (for the application method): immediate | pending-reboot

    You can use the immediate value with dynamic parameters only. You can use the pending-reboot value for both dynamic and static parameters.

    When the application method is immediate, changes to dynamic parameters are applied immediately to the DB instances associated with the parameter group.

    When the application method is pending-reboot, changes to dynamic and static parameters are applied after a reboot without failover to the DB instances associated with the parameter group.

    You can't use pending-reboot with dynamic parameters on RDS for SQL Server DB instances. Use immediate.

    Default: All parameter types returned

    Valid Values: user | system | engine-default

  • :filters (Array<Types::Filter>) —

    A filter that specifies one or more DB parameters to describe.

    The only supported filter is parameter-name. The results list only includes information about the DB parameters with these names.

#wait_until(options = {}) {|resource| ... } ⇒ Resource

Deprecated.

Use [Aws::RDS::Client] #wait_until instead

Note:

The waiting operation is performed on a copy. The original resource remains unchanged.

Waiter polls an API operation until a resource enters a desired state.

Basic Usage

Waiter will polls until it is successful, it fails by entering a terminal state, or until a maximum number of attempts are made.

# polls in a loop until condition is true
resource.wait_until(options) {|resource| condition}

Example

instance.wait_until(max_attempts:10, delay:5) do |instance|
  instance.state.name == 'running'
end

Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. The waiting condition is set by passing a block to #wait_until:

# poll for ~25 seconds
resource.wait_until(max_attempts:5,delay:5) {|resource|...}

Callbacks

You can be notified before each polling attempt and before each delay. If you throw :success or :failure from these callbacks, it will terminate the waiter.

started_at = Time.now
# poll for 1 hour, instead of a number of attempts
proc = Proc.new do |attempts, response|
  throw :failure if Time.now - started_at > 3600
end

  # disable max attempts
instance.wait_until(before_wait:proc, max_attempts:nil) {...}

Handling Errors

When a waiter is successful, it returns the Resource. When a waiter fails, it raises an error.

begin
  resource.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
  # resource did not enter the desired state in time
end

attempts attempt in seconds invoked before each attempt invoked before each wait

Parameters:

  • options (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (options):

  • :max_attempts (Integer) — default: 10 —

    Maximum number of

  • :delay (Integer) — default: 10 —

    Delay between each

  • :before_attempt (Proc) — default: nil —

    Callback

  • :before_wait (Proc) — default: nil —

    Callback

Yield Parameters:

  • resource (Resource) —

    to be used in the waiting condition.

Returns:

  • (Resource) —

    if the waiter was successful

Raises:

  • (Aws::Waiters::Errors::FailureStateError) —

    Raised when the waiter terminates because the waiter has entered a state that it will not transition out of, preventing success.

    yet successful.

  • (Aws::Waiters::Errors::UnexpectedError) —

    Raised when an error is encountered while polling for a resource that is not expected.

  • (NotImplementedError) —

    Raised when the resource does not
