Instance Method Details

#attribute_valuesArray<String>

The value or values for the manual DB snapshot attribute.

If the AttributeName field is set to restore, then this element returns a list of IDs of the Amazon Web Services accounts that are authorized to copy or restore the manual DB snapshot. If a value of all is in the list, then the manual DB snapshot is public and available for any Amazon Web Services account to copy or restore.

Returns:

  • (Array<String>)

#data_loaded?Boolean

Returns true if this resource is loaded. Accessing attributes or #data on an unloaded resource will trigger a call to #load.

Returns:

  • (Boolean)

    Returns true if this resource is loaded. Accessing attributes or #data on an unloaded resource will trigger a call to #load.

#modify(options = {}) ⇒ Types::ModifyDBSnapshotAttributeResult

Examples:

Request syntax with placeholder values


db_snapshot_attribute.modify({
  values_to_add: ["String"],
  values_to_remove: ["String"],
})

Parameters:

  • options (Hash) (defaults to: {})

    ({})

Options Hash (options):

  • :values_to_add (Array<String>)

    A list of DB snapshot attributes to add to the attribute specified by AttributeName.

    To authorize other Amazon Web Services accounts to copy or restore a manual snapshot, set this list to include one or more Amazon Web Services account IDs, or all to make the manual DB snapshot restorable by any Amazon Web Services account. Do not add the all value for any manual DB snapshots that contain private information that you don't want available to all Amazon Web Services accounts.

  • :values_to_remove (Array<String>)

    A list of DB snapshot attributes to remove from the attribute specified by AttributeName.

    To remove authorization for other Amazon Web Services accounts to copy or restore a manual snapshot, set this list to include one or more Amazon Web Services account identifiers, or all to remove authorization for any Amazon Web Services account to copy or restore the DB snapshot. If you specify all, an Amazon Web Services account whose account ID is explicitly added to the restore attribute can still copy or restore the manual DB snapshot.

Returns:

#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
